Conformal-Based Surface Morphing and Multi-Scale Representation
Axioms, 2014 This paper presents two algorithms, based on conformal geometry, for the multi-scale representations of geometric shapes and surface morphing. A multi-scale surface representation aims to describe a 3D shape at different levels of geometric detail, which

Mathematical basics of motion and deformation in computer graphics
International Conference on Computer Graphics and Interactive Techniques, 2014 This synthesis lecture presents an intuitive introduction to the mathematics of motion and deformation in computer graphics. Starting with familiar concepts in graphics, such as Euler angles, quaternions, and affine transformations, we illustrate that a ...

OperatorNet: Recovering 3D Shapes From Difference Operators [PDF]
, 2019 This paper proposes a learning-based framework for reconstructing 3D shapes from functional operators, compactly encoded as small-sized matrices. To this end we introduce a novel neural architecture, called OperatorNet, which takes as input a set of ...
