SUMMARY:Cages, Deformation, & Interpolation
DESCRIPTION:CageNet: A Meta-Framework for Learning on Wild Meshes\n\nWe pr
 opose a framework for learning on in-the-wild meshes containing non-manifo
 ld elements, multiple components, and interior structures. Our approach us
 es cages and generalized barycentric coordinates to parametrize and learn 
 volumetric functions, demonstrated by segmentation and skinning weights, .

 xible 3D Cage-based Deformation via Green Coordinates on Bézier Patches\n\
 nThis work constructs Green coordinates for cages composed of Bézier patch
 es, which enables flexible deformations with curved boundaries. The high-o
 rder structure also allows us to create a compact curved cage for the inpu

 rdinates for 2D Polynomial Cages\n\nWe present analytical formulas for eva

 ns, for 2D cages made of polynomial arcs.\nWe present results of 2D image 
 deformations by direct interaction with the cage and through variational s
 olvers.\nWe demonstrate the flexibility\n\n\nElie Michel, Alec Jacobson, S

 -------\nOn Planar Shape Interpolation With Logarithmic Metric Blending\n\
 nLogarithmic metric blending enables smooth interpolation between planar s
 hapes while bounding both conformal and area distortions. By blending symm
