  text: 'In this work, we present intrinsic shape context (ISC) descriptors for 3D
    shapes. We generalize to surfaces the polar sampling of the image domain used
    in shape contexts: for this purpose, we chart the surface by shooting geodesic
    outwards from the point being analyzed; `angle'' is treated as tantamount to geodesic
    shooting direction, and radius as geodesic distance. To deal with orientation
    ambiguity, we exploit properties of the Fourier transform. Our charting method
    is intrinsic, i.e., invariant to isometric shape transformations. The resulting
    descriptor is a meta-descriptor that can be applied to any photometric or geometric
    property field defined on the shape, in particular, we can leverage recent developments
    in intrinsic shape analysis and construct ISC based on state-of-the-art dense
    shape descriptors such as heat kernel signatures. Our experiments demonstrate
    a notable improvement in shape matching on standard benchmarks.'
