text: We propose an efficient method to model paper tearing in the context of interactive
modeling. The method uses geometrical information to automatically detect potential
starting points of tears. We further introduce a new hybrid geometrical and physical-based
method to compute the trajectory of tears while procedurally synthesizing high
resolution details of the tearing path using a texture based approach. The results
obtained are compared with real paper and with previous studies on the expected
geometric paths of paper that tears.

text: One of the major challenges in physically based modelling is making simulations
efficient. Adaptive models provide an essential solution to these efficiency goals.
These models are able to self-adapt in space and time, attempting to provide the
best possible compromise between accuracy and speed. This survey reviews the adaptive
solutions proposed so far in computer graphics. Models are classified according
to the strategy they use for adaptation, from time-stepping and freezing techniques
to geometric adaptivity in the form of structured grids, meshes and particles.
Applications range from fluids, through deformable bodies, to articulated solids.

text: We propose a new memetic strategy that can solve the multi-physics, complex
inverse problems, formulated as the multi-objective optimization ones, in which
objectives are misfits between the measured and simulated states of various governing
processes. The multi-deme structure of the strategy allows for both, intensive,
relatively cheap exploration with a moderate accuracy and more accurate search
many regions of Pareto set in parallel. The special type of selection operator
prefers the coherent alternative solutions, eliminating artifacts appearing in
the particular processes. The additional accuracy increment is obtained by the
parallel convex searches applied to the local scalarizations of the misfit vector.
The strategy is dedicated for solving ill-conditioned problems, for which inverting
the single physical process can lead to the ambiguous results. The skill of the
selection in artifact elimination is shown on the benchmark problem, while the
whole strategy was applied for identification of oil deposits, where the misfits
are related to various frequencies of the magnetic and electric waves of the magnetotelluric
measurements. 2016 Elsevier B.V.

text: 'A major open problem on the road to artificial intelligence is the development
of incrementally learning systems that learn about more and more concepts over
time from a stream of data. In this work, we introduce a new training strategy,
iCaRL, that allows learning in such a class-incremental way: only the training
data for a small number of classes has to be present at the same time and new
classes can be added progressively. iCaRL learns strong classifiers and a data
representation simultaneously. This distinguishes it from earlier works that were
fundamentally limited to fixed data representations and therefore incompatible
with deep learning architectures. We show by experiments on CIFAR-100 and ImageNet
ILSVRC 2012 data that iCaRL can learn many classes incrementally over a long period
of time where other strategies quickly fail. '

text: 'This thesis describes a brittle fracture simulation method for visual effects
applications. Building upon a symmetric Galerkin boundary element method, we first
compute stress intensity factors following the theory of linear elastic fracture
mechanics. We then use these stress intensities to simulate the motion of a propagating
crack front at a significantly higher resolution than the overall deformation
of the breaking object. Allowing for spatial variations of the material''s toughness
during crack propagation produces visually realistic, highly-detailed fracture
surfaces. Furthermore, we introduce approximations for stress intensities and
crack opening displacements, resulting in both practical speed-up and theoretically
superior runtime complexity compared to previous methods. While we choose a quasi-static
approach to fracture mechanics, ignoring dynamic deformations, we also couple
our fracture simulation framework to a standard rigid-body dynamics solver, enabling
visual effects artists to simulate both large scale motion, as well as fracturing
due to collision forces in a combined system. As fractures inside of an object
grow, their geometry must be represented both in the coarse boundary element mesh,
as well as at the desired fine output resolution. Using a boundary element method,
we avoid complicated volumetric meshing operations. Instead we describe a simple
set of surface meshing operations that allow us to progressively add cracks to
the mesh of an object and still re-use all previously computed entries of the
linear boundary element system matrix. On the high resolution level, we opt for
an implicit surface representation. We then describe how to capture fracture surfaces
during crack propagation, as well as separate the individual fragments resulting
from the fracture process, based on this implicit representation. We show results
obtained with our method, either solving the full boundary element system in every
time step, or alternatively using our fast approximations. These results demonstrate
that both of these methods perform well in basic test cases and produce realistic
fracture surfaces. Furthermore we show that our fast approximations substantially
out-perform the standard approach in more demanding scenarios. Finally, these
two methods naturally combine, using the full solution while the problem size
is manageably small and switching to the fast approximations later on. The resulting
hybrid method gives the user a direct way to choose between speed and accuracy
of the simulation. '

text: We propose an interactive sculpting system for seamlessly editing pre-computed
animations of liquid, without the need for any resimulation. The input is a sequence
of meshes without correspondences representing the liquid surface over time. Our
method enables the efficient selection of consistent space-time parts of this
animation, such as moving waves or droplets, which we call space-time features.
Once selected, a feature can be copied, edited, or duplicated and then pasted
back anywhere in space and time in the same or in another liquid animation sequence.
Our method circumvents tedious user interactions by automatically computing the
spatial and temporal ranges of the selected feature. We also provide space-time
shape editing tools for non-uniform scaling, rotation, trajectory changes, and
temporal editing to locally speed up or slow down motion. Using our tools, the
user can edit and progressively refine any input simulation result, possibly using
a library of precomputed space-time features extracted from other animations.
In contrast to the trial-and-error loop usually required to edit animation results
through the tuning of indirect simulation parameters, our method gives the user
full control over the edited space-time behaviors. © 2016 Copyright held by the

text: In this paper we introduce the Multiobjective Optimization Hierarchic Genetic
Strategy with maturing (MO-mHGS), a meta-algorithm that performs evolutionary
optimization in a hierarchy of populations. The maturing mechanism improves growth
and reduces redundancy. The performance of MO-mHGS with selected state-of-the-art
multiobjective evolutionary algorithms as internal algorithms is analysed on benchmark
problems and their modifications for which single fitness evaluation time depends
on the solution accuracy. We compare the proposed algorithm with the Island Model
Genetic Algorithm as well as with single-deme methods, and discuss the impact
of internal algorithms on the MO-mHGS meta-algorithm. © 2016 Elsevier B.V.

text: When aiming to seamlessly integrate a fluid simulation into a larger scenario
(like an open ocean), careful attention must be paid to boundary conditions. In
particular, one must implement special "non-reflecting" boundary conditions,
which dissipate out-going waves as they exit the simulation. Unfortunately, the
state of the art in non-reflecting boundary conditions (perfectly-matched layers,
or PMLs) only permits trivially simple inflow/outflow conditions, so there is
no reliable way to integrate a fluid simulation into a more complicated environment
like a stormy ocean or a turbulent river. This paper introduces the first method
for combining nonreflecting boundary conditions based on PMLs with inflow/outflow
boundary conditions that vary arbitrarily throughout space and time. Our algorithm
is a generalization of stateof- the-art mean-flow boundary conditions in the computational
fluid dynamics literature, and it allows for seamless integration of a fluid simulation
into much more complicated environments. Our method also opens the door for previously-unseen
postprocess effects like retroactively changing the location of solid obstacles,
and locally increasing the visual detail of a pre-existing simulation.

text: We propose a novel surface-only technique for simulating incompressible, inviscid
and uniform-density liquids with surface tension in three dimensions. The liquid
surface is captured by a triangle mesh on which a Lagrangian velocity field is
stored. Because advection of the velocity field may violate the incompressibility
condition, we devise an orthogonal projection technique to remove the divergence
while requiring the evaluation of only two boundary integrals. The forces of surface
tension, gravity, and solid contact are all treated by a boundary element solve,
allowing us to perform detailed simulations of a wide range of liquid phenomena,
including waterbells, droplet and jet collisions, fluid chains, and crown splashes.

text: Combining high-resolution level set surface tracking with lower resolution
physics is an inexpensive method for achieving highly detailed liquid animations.
Unfortunately, the inherent resolution mismatch introduces several types of disturbing
visual artifacts. We identify the primary sources of these artifacts and present
simple, efficient, and practical solutions to address them. First, we propose
an unconditionally stable filtering method that selectively removes sub-grid surface
artifacts not seen by the fluid physics, while preserving fine detail in dynamic
splashing regions. It provides comparable results to recent error-correction techniques
at lower cost, without substepping, and with better scaling behavior. Second,
we show how a modified narrow-band scheme can ensure accurate free surface boundary
conditions in the presence of large resolution mismatches. Our scheme preserves
the efficiency of the narrow-band methodology, while eliminating objectionable
stairstep artifacts observed in prior work. Third, we demonstrate that the use
of linear interpolation of velocity during advection of the high-resolution level
set surface is responsible for visible grid-aligned kinks; we therefore advocate
higher-order velocity interpolation, and show that it dramatically reduces this
artifact. While these three contributions are orthogonal, our results demonstrate
that taken together they efficiently address the dominant sources of visual artifacts
arising with high-resolution embedded liquid surfaces; the proposed approach offers
improved visual quality, a straightforward implementation, and substantially greater
scalability than competing methods.

text: This paper generalizes the well-known Diffusion Curves Images (DCI), which
are composed of a set of Bezier curves with colors specified on either side. These
colors are diffused as Laplace functions over the image domain, which results
in smooth color gradients interrupted by the Bezier curves. Our new formulation
allows for more color control away from the boundary, providing a similar expressive
power as recent Bilaplace image models without introducing associated issues and
computational costs. The new model is based on a special Laplace function blending
and a new edge blur formulation. We demonstrate that given some user-defined boundary
curves over an input raster image, fitting colors and edge blur from the image
to the new model and subsequent editing and animation is equally convenient as
with DCIs. Numerous examples and comparisons to DCIs are presented.

text: The Fluid Implicit Particle method (FLIP) for liquid simulations uses particles
to reduce numerical dissipation and provide important visual cues for events like
complex splashes and small-scale features near the liquid surface. Unfortunately,
FLIP simulations can be computationally expensive, because they require a dense
sampling of particles to fill the entire liquid volume. Furthermore, the vast
majority of these FLIP particles contribute nothing to the fluid's visual appearance,
especially for larger volumes of liquid. We present a method that only uses FLIP
particles within a narrow band of the liquid surface, while efficiently representing
the remaining inner volume on a regular grid. We show that a naïve realization
of this idea introduces unstable and uncontrollable energy fluctuations, and we
propose a novel coupling scheme between FLIP particles and regular grid which
overcomes this problem. Our method drastically reduces the particle count and
simulation times while yielding results that are nearly indistinguishable from
regular FLIP simulations. Our approach is easy to integrate into any existing
FLIP implementation.

text: We present a boundary element based method for fast simulation of brittle
fracture. By introducing simplifying assumptions that allow us to quickly estimate
stress intensities and opening displacements during crack propagation, we build
a fracture algorithm where the cost of each time step scales linearly with the
length of the crackfront. The transition from a full boundary element method to
our faster variant is possible at the beginning of any time step. This allows
us to build a hybrid method, which uses the expensive but more accurate BEM while
the number of degrees of freedom is low, and uses the fast method once that number
exceeds a given threshold as the crack geometry becomes more complicated. Furthermore,
we integrate this fracture simulation with a standard rigid-body solver. Our rigid-body
coupling solves a Neumann boundary value problem by carefully separating translational,
rotational and deformational components of the collision forces and then applying
a Tikhonov regularizer to the resulting linear system. We show that our method
produces physically reasonable results in standard test cases and is capable of
dealing with complex scenes faster than previous finite- or boundary element approaches.

text: "Computer graphics is an extremely exciting field for two reasons. On the
one hand,\r\nthere is a healthy injection of pragmatism coming from the visual
effects industry\r\nthat want robust algorithms that work so they can produce
results at an increasingly\r\nfrantic pace. On the other hand, they must always
try to push the envelope and\r\nachieve the impossible to wow their audiences
in the next blockbuster, which means\r\nthat the industry has not succumb to conservatism,
and there is plenty of room to\r\ntry out new and crazy ideas if there is a chance
that it will pan into something\r\nuseful.\r\nWater simulation has been in visual
effects for decades, however it still remains\r\nextremely challenging because
of its high computational cost and difficult artdirectability.\r\nThe work in
this thesis tries to address some of these difficulties.\r\nSpecifically, we make
the following three novel contributions to the state-of-the-art\r\nin water simulation
for visual effects.\r\nFirst, we develop the first algorithm that can convert
any sequence of closed\r\nsurfaces in time into a moving triangle mesh. State-of-the-art
methods at the time\r\ncould only handle surfaces with fixed connectivity, but
we are the first to be able to\r\nhandle surfaces that merge and split apart.
This is important for water simulation\r\npractitioners, because it allows them
to convert splashy water surfaces extracted\r\nfrom particles or simulated using
grid-based level sets into triangle meshes that can\r\nbe either textured and
enhanced with extra surface dynamics as a post-process.\r\nWe also apply our algorithm
to other phenomena that merge and split apart, such\r\nas morphs and noisy reconstructions
of human performances.\r\nSecond, we formulate a surface-based energy that measures
the deviation of a\r\nwater surface froma physically valid state. Such discrepancies
arise when there is a\r\nmismatch in the degrees of freedom between the water
surface and the underlying\r\nphysics solver. This commonly happens when practitioners
use a moving triangle\r\nmesh with a grid-based physics solver, or when high-resolution
grid-based surfaces\r\nare combined with low-resolution physics. Following the
direction of steepest\r\ndescent on our surface-based energy, we can either smooth
these artifacts or turn\r\nthem into high-resolution waves by interpreting the
energy as a physical potential.\r\nThird, we extend state-of-the-art techniques
in non-reflecting boundaries to handle spatially and time-varying background flows.
This allows a novel new\r\nworkflow where practitioners can re-simulate part of
an existing simulation, such\r\nas removing a solid obstacle, adding a new splash
or locally changing the resolution.\r\nSuch changes can easily lead to new waves
in the re-simulated region that would\r\nreflect off of the new simulation boundary,
effectively ruining the illusion of a\r\nseamless simulation boundary between
the existing and new simulations. Our\r\nnon-reflecting boundaries makes sure
that such waves are absorbed."
acknowledgement: "First and foremost I would like to thank Chris. I have been incredibly
lucky to have\r\nyou as my advisor. Your integrity and aspiration to do the right
thing in all walks of\r\nlife is something I admire and aspire to. I also really
appreciate the fact that when\r\nworking with you it felt like we were equals. I
think we had a very synergetic work\r\nrelationship: I learned immensely from you,
but I dare say that you learned a few\r\nthings from me as well. ;)\r\nNext, I would
like to thank my amazing committee. Hao, it was a fantastic\r\nexperience working
with you. You showed me how to persevere and keep morale\r\nhigh when things were
looking the most bleak before the deadline. You are an\r\nincredible motivator and
super fun to be around! Vladimir, thanks for the shared\r\nlunches and the poker
games. Sorry for not bringing them back when I got busy.\r\nAlso, sorry for embarrassing
you by asking about your guitar playing that one\r\ntime. You really are quite awesome!
Nils, one of the friendliest and most humble\r\npeople you will meet and a top notch
researcher to boot! Thank you for joining\r\nmy committee late!\r\nI would also
like to acknowledge the Visual Computing group at IST Austria\r\nfrom whom I have
learned so much. The excellent discussions we had in reading\r\ngroups and research
meetings really helped me become a better researcher!\r\nNext, I would like to thank
all the amazing people that I met during my PhD\r\nstudies, both at IST Austria,
in Vienna and elsewhere. "

text: Simulating the delightful dynamics of soap films, bubbles, and foams has traditionally
required the use of a fully three-dimensional many-phase Navier-Stokes solver,
even though their visual appearance is completely dominated by the thin liquid
surface. We depart from earlier work on soap bubbles and foams by noting that
their dynamics are naturally described by a Lagrangian vortex sheet model in which
circulation is the primary variable. This leads us to derive a novel circulation-preserving
surface-only discretization of foam dynamics driven by surface tension on a non-manifold
triangle mesh. We represent the surface using a mesh-based multimaterial surface
tracker which supports complex bubble topology changes, and evolve the surface
according to the ambient air flow induced by a scalar circulation field stored
on the mesh. Surface tension forces give rise to a simple update rule for circulation,
even at non-manifold Plateau borders, based on a discrete measure of signed scalar
mean curvature. We further incorporate vertex constraints to enable the interaction
of soap films with wires. The result is a method that is at once simple, robust,
and efficient, yet able to capture an array of soap films behaviors including
foam rearrangement, catenoid collapse, blowing bubbles, and double bubbles being
pulled apart.

text: "This paper presents a liquid simulation technique that enforces the incompressibility
condition using a stream function solve instead of a pressure projection. Previous
methods have used stream function techniques for the simulation of detailed single-phase
flows, but a formulation for liquid simulation has proved elusive in part due
to the free surface boundary conditions. In this paper, we introduce a stream
function approach to liquid simulations with novel boundary conditions for free
surfaces, solid obstacles, and solid-fluid coupling.\r\n\r\nAlthough our approach
increases the dimension of the linear system necessary to enforce incompressibility,
it provides interesting and surprising benefits. First, the resulting flow is
guaranteed to be divergence-free regardless of the accuracy of the solve. Second,
our free-surface boundary conditions guarantee divergence-free motion even in
the un-simulated air phase, which enables two-phase flow simulation by only computing
a single phase. We implemented this method using a variant of FLIP simulation
which only samples particles within a narrow band of the liquid surface, and we
illustrate the effectiveness of our method for detailed two-phase flow simulations
with complex boundaries, detailed bubble interactions, and two-way solid-fluid
coupling."

text: We present a method to learn and propagate shape placements in 2D polygonal
scenes from a few examples provided by a user. The placement of a shape is modeled
as an oriented bounding box. Simple geometric relationships between this bounding
box and nearby scene polygons define a feature set for the placement. The feature
sets of all example placements are then used to learn a probabilistic model over
all possible placements and scenes. With this model, we can generate a new set
of placements with similar geometric relationships in any given scene. We introduce
extensions that enable propagation and generation of shapes in 3D scenes, as
well as the application of a learned modeling session to large scenes without
additional user interaction. These concepts allow us to generate complex scenes
with thousands of objects with relatively little user interaction.

text: This work presents a method for efficiently simplifying the pressure projection
step in a liquid simulation. We first devise a straightforward dimension reduction
technique that dramatically reduces the cost of solving the pressure projection.
Next, we introduce a novel change of basis that satisfies free-surface boundary
conditions exactly, regardless of the accuracy of the pressure solve. When combined,
these ideas greatly reduce the computational complexity of the pressure solve
without compromising free surface boundary conditions at the highest level of
detail. Our techniques are easy to parallelize, and they effectively eliminate
the computational bottleneck for large liquid simulations.

of water that interact with their environment. Our contributions include: a novel
wavefront tracking technique that enables dispersion, refraction, reflection,
and diffraction in the same simulation; a unique multivalued function interpolation
method that enables our simulations to elegantly sidestep the Nyquist limit; a
dispersion approximation for efficiently amplifying the number of simulated waves
by several orders of magnitude; and additional extensions that allow for time-dependent
effects and interactive artistic editing of the resulting animation. Our contributions
combine to give us multitudes more wave details than similar algorithms, while
maintaining high frame rates and allowing close camera zooms.'

text: "We present a method for simulating brittle fracture under the assumptions
of quasi-static linear elastic fracture mechanics (LEFM). Using the boundary element
method (BEM) and Lagrangian crack-fronts, we produce highly detailed fracture
surfaces. The computational cost of the BEM is alleviated by using a low-resolution
mesh and interpolating the resulting stress intensity factors when propagating
the high-resolution crack-front.\r\n\r\nOur system produces physics-based fracture
surfaces with high spatial and temporal resolution, taking spatial variation of
material toughness and/or strength into account. It also allows for crack initiation
to be handled separately from crack propagation, which is not only more reasonable
from a physics perspective, but can also be used to control the simulation.\r\n\r\nSeparating
the resolution of the crack-front from the resolution of the computational mesh
increases the efficiency and therefore the amount of visual detail on the resulting
fracture surfaces. The BEM also allows us to re-use previously computed blocks
of the system matrix."

text: We propose a method for propagating edit operations in 2D vector graphics,
based on geometric relationship functions. These functions quantify the geometric
relationship of a point to a polygon, such as the distance to the boundary or
the direction to the closest corner vertex. The level sets of the relationship
functions describe points with the same relationship to a polygon. For a given
query point, we first determine a set of relationships to local features, construct
all level sets for these relationships, and accumulate them. The maxima of the
resulting distribution are points with similar geometric relationships. We show
extensions to handle mirror symmetries, and discuss the use of relationship functions
as local coordinate systems. Our method can be applied, for example, to interactive
floorplan editing, and it is especially useful for large layouts, where individual
edits would be cumbersome. We demonstrate populating 2D layouts with tens to hundreds
of objects by propagating relatively few edit operations.

text: In this paper, we present a method for non-rigid, partial shape matching in
vector graphics. Given a user-specified query region in a 2D shape, similar regions
are found, even if they are non-linearly distorted. Furthermore, a non-linear
mapping is established between the query regions and these matches, which allows
the automatic transfer of editing operations such as texturing. This is achieved
by a two-step approach. First, pointwise correspondences between the query region
and the whole shape are established. The transformation parameters of these correspondences
are registered in an appropriate transformation space. For transformations between
similar regions, these parameters form surfaces in transformation space, which
are extracted in the second step of our method. The extracted regions may be related
to the query region by a non-rigid transform, enabling non-rigid shape matching.

text: In this paper, we introduce a novel scene representation for the visualization
of large-scale point clouds accompanied by a set of high-resolution photographs.
Many real-world applications deal with very densely sampled point-cloud data,
which are augmented with photographs that often reveal lighting variations and
inaccuracies in registration. Consequently, the high-quality representation of
the captured data, i.e., both point clouds and photographs together, is a challenging
and time-consuming task. We propose a two-phase approach, in which the first (preprocessing)
phase generates multiple overlapping surface patches and handles the problem of
seamless texture generation locally for each patch. The second phase stitches
these patches at render-time to produce a high-quality visualization of the data.
As a result of the proposed localization of the global texturing problem, our
algorithm is more than an order of magnitude faster than equivalent mesh-based
texturing techniques. Furthermore, since our preprocessing phase requires only
a minor fraction of the whole data set at once, we provide maximum flexibility
when dealing with growing data sets.

text: We present a method for smoothly blending between existing liquid animations.
We introduce a semi-automatic method for matching two existing liquid animations,
which we use to create new fluid motion that plausibly interpolates the input.
Our contributions include a new space-time non-rigid iterative closest point algorithm
that incorporates user guidance, a subsampling technique for efficient registration
of meshes with millions of vertices, and a fast surface extraction algorithm that
produces 3D triangle meshes from a 4D space-time surface. Our technique can be
used to instantly create hundreds of new simulations, or to interactively explore
complex parameter spaces. Our method is guaranteed to produce output that does
not deviate from the input animations, and it generalizes to multiple dimensions.
Because our method runs at interactive rates after the initial precomputation
step, it has potential applications in games and training simulations.

text: 'We introduce a new method for efficiently simulating liquid with extreme
amounts of spatial adaptivity. Our method combines several key components to drastically
speed up the simulation of large-scale fluid phenomena: We leverage an alternative
Eulerian tetrahedral mesh discretization to significantly reduce the complexity
of the pressure solve while increasing the robustness with respect to element
quality and removing the possibility of locking. Next, we enable subtle free-surface
phenomena by deriving novel second-order boundary conditions consistent with our
discretization. We couple this discretization with a spatially adaptive Fluid-Implicit
Particle (FLIP) method, enabling efficient, robust, minimally-dissipative simulations
that can undergo sharp changes in spatial resolution while minimizing artifacts.
Along the way, we provide a new method for generating a smooth and detailed surface
from a set of particles with variable sizes. Finally, we explore several new sizing
functions for determining spatially adaptive simulation resolutions, and we show
how to couple them to our simulator. We combine each of these elements to produce
a simulation algorithm that is capable of creating animations at high maximum
resolutions while avoiding common pitfalls like inaccurate boundary conditions
and inefficient computation.'

text: This paper presents a method for computing topology changes for triangle meshes
in an interactive geometric modeling environment. Most triangle meshes in practice
do not exhibit desirable geometric properties, so we develop a solution that is
independent of standard assumptions and robust to geometric errors. Specifically,
we provide the first method for topology change applicable to arbitrary non-solid,
non-manifold, non-closed, self-intersecting surfaces. We prove that this new method
for topology change produces the expected conventional results when applied to
solid (closed, manifold, non-self-intersecting) surfaces---that is, we prove a
backwards-compatibility property relative to prior work. Beyond solid surfaces,
we present empirical evidence that our method remains tolerant to a variety of
surface aberrations through the incorporation of a novel error correction scheme.
Finally, we demonstrate how topology change applied to non-solid objects enables
wholly new and useful behaviors.

text: Our work concerns the combination of an Eulerian liquid simulation with a
high-resolution surface tracker (e.g. the level set method or a Lagrangian triangle
mesh). The naive application of a high-resolution surface tracker to a low-resolution
velocity field can produce many visually disturbing physical and topological artifacts
that limit their use in practice. We address these problems by defining an error
function which compares the current state of the surface tracker to the set of
physically valid surface states. By reducing this error with a gradient descent
technique, we introduce a novel physics-based surface fairing method. Similarly,
by treating this error function as a potential energy, we derive a new surface
correction force that mimics the vortex sheet equations. We demonstrate our results
with both level set and mesh-based surface trackers.

text: "We present an approach for artist-directed animation of liquids using multiple
levels of control over the simulation, ranging from the overall tracking of desired
shapes to highly detailed secondary effects such as dripping streams, separating
sheets of fluid, surface waves and ripples. The first portion of our technique
is a volume preserving morph that allows the animator to produce a plausible fluid-like
motion from a sparse set of control meshes. By rasterizing the resulting control
meshes onto the simulation grid, the mesh velocities act as boundary conditions
during the projection step of the fluid simulation. We can then blend this motion
together with uncontrolled fluid velocities to achieve a more relaxed control
over the fluid that captures natural inertial effects. Our method can produce
highly detailed liquid surfaces with control over sub-grid details by using a
mesh-based surface tracker on top of a coarse grid-based fluid simulation. We
can create ripples and waves on the fluid surface attracting the surface mesh
to the control mesh with spring-like forces and also by running a wave simulation
over the surface mesh. Our video results demonstrate how our control scheme can
be used to create animated characters and shapes that are made of water.\r\n"

text: We present a method for recovering a temporally coherent, deforming triangle
mesh with arbitrarily changing topology from an incoherent sequence of static
closed surfaces. We solve this problem using the surface geometry alone, without
any prior information like surface templates or velocity fields. Our system combines
a proven strategy for triangle mesh improvement, a robust multi-resolution non-rigid
registration routine, and a reliable technique for changing surface mesh topology.
We also introduce a novel topological constraint enforcement algorithm to ensure
that the output and input always have similar topology. We apply our technique
to a series of diverse input data from video reconstructions, physics simulations,
and artistic morphs. The structured output of our algorithm allows us to efficiently
track information like colors and displacement maps, recover velocity information,
and solve PDEs on the mesh as a post process.

text: We introduce the idea of using an explicit triangle mesh to track the air/fluid
interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial
surface mesh is created, this mesh is carried forward in time using nearby particle
velocities to advect the mesh vertices. The mesh connectivity remains mostly unchanged
across time-steps; it is only modified locally for topology change events or for
the improvement of triangle quality. In order to ensure that the surface mesh
does not diverge from the underlying particle simulation, we periodically project
the mesh surface onto an implicit surface defined by the physics simulation. The
mesh surface gives us several advantages over previous SPH surface tracking techniques.
We demonstrate a new method for surface tension calculations that clearly outperforms
the state of the art in SPH surface tension for computer graphics. We also demonstrate
a method for tracking detailed surface information (like colors) that is less
susceptible to numerical diffusion than competing techniques. Finally, our temporally-coherent
surface mesh allows us to simulate high-resolution surface wave dynamics without
being limited by the particle resolution of the SPH simulation.

text: We present a new algorithm for enforcing incompressibility for Smoothed Particle
Hydrodynamics (SPH) by preserving uniform density across the domain. We propose
a hybrid method that uses a Poisson solve on a coarse grid to enforce a divergence
free velocity field, followed by a local density correction of the particles. This
avoids typical grid artifacts and maintains the Lagrangian nature of SPH by directly
transferring pressures onto particles. Our method can be easily integrated with
existing SPH techniques such as the incompressible PCISPH method as well as weakly
compressible SPH by adding an additional force term. We show that this hybrid
method accelerates convergence towards uniform density and permits a significantly
larger time step compared to earlier approaches while producing similar results.
We demonstrate our approach in a variety of scenarios with significant pressure
gradients such as splashing liquids.

text: "Animating detailed liquid surfaces has always been a challenge for computer
graphics researchers and visual effects artists. Over the past few years, researchers
in this field have focused on mesh-based surface tracking to synthesize extremely
detailed liquid surfaces as efficiently as possible. This course provides a solid
understanding of the steps required to create a fluid simulator with a mesh-based
liquid surface.\r\n\r\nThe course begins with an overview of several existing
liquid-surface-tracking techniques and the pros and cons of each method. Then
it explains how to embed a triangle mesh into a finite-difference-based fluid
simulator and describes several methods for allowing the liquid surface to merge
together or break apart. The final section showcases the benefits and further
applications of a mesh-based liquid surface, highlighting state-of-the-art methods
for tracking colors and textures, maintaining liquid volume, preserving small
surface features, and simulating realistic surface-tension waves."
