One Point Isometric Matching with the Heat Kernel
(2010)
A common operation in many geometry processing algorithms consists of finding correspondences between pairs of shapes by finding structure-preserving maps between them. A particularly useful case of such maps is isometries, ...
Feature Preserving Mesh Generation from 3D Point Clouds
(2010)
We address the problem of generating quality surface triangle meshes from 3D point clouds sampled on piecewise smooth surfaces. Using a feature detection process based on the covariance matrices of Voronoi cells, we first ...
