However, applying texture maps to dynamic deformable surfaces presents a significant challenge, due to ever-shifting differences in length scales involved. When these surfaces move and advect the texture along with them, their final appearance degrades as deformed regions dramatically distort their texture map. Modifications to the texture directly at the pixel level in response to the deformation may introduce ghosting artifacts and look unnatural. In the real world, the appearance of surface details on a deforming material changes through the interplay of physical processes such as rupturing, exposure of internal structure, or wrinkling. Motivated by these behaviors, in this work we explore how physical principles can guide the texturing methods based on the measure of surface deformation. We present two novel wave-based procedural texturing algorithms which reproduce common physical properties like advection and self-similarity, enabling the plausible animation of deforming objects with extreme texture map distortions. Our algorithms are fully procedural, require no actual physics simulation, and store no state or history of deformation besides the input UV map, making them highly parallelizable on the GPU and efficient enough for real-time applications. We show the versatility of the method by animating physical phenomena with extreme deformations such as flowing lava, stretching putty and outpouring sludge. https://research-explorer.ista.ac.at/download/21923/21924/tog454-article154-supplemental.mp4 video/mp4no https://research-explorer.ista.ac.at/download/21923/21925/tog454-article154-video.mp4 video/mp4no https://research-explorer.ista.ac.at/download/21923/21926/tog454-article154-supplemental.pdf application/pdfno https://research-explorer.ista.ac.at/download/21923/21927/tog454-article154-main-1.pdf application/pdfno https://creativecommons.org/licenses/by/4.0/ ACM2026Los Angeles, CA, United States eng Procedural animation 0730-030110.1145/3811353 454 Kalinov, Aleksei, et al. “Physics-Inspired Procedural Texturing of Extremely Deformable Surfaces.” <i>ACM Transactions on Graphics</i>, vol. 45, no. 4, 154, ACM, doi:<a href="https://doi.org/10.1145/3811353">10.1145/3811353</a>.
