cazhang / shellpca

An implementation of ShellPCA with demo

shellPCA: code of ShellPCA paper

The code implements a simple demo to show how to use ShellPCA given a bunch of meshes (.ply).

Dependency

The code is implemented based on quocMesh library http://numod.ins.uni-bonn.de/software/quocmesh/ To run the demo, you need to follow instructions there first. Once installation is done, the script could be added and compiled.

Averaging

The spheres demo uses linear average although an elastic average is expected to perform better You can find the script to compute elastic average under quocMesh repositories easily

Usage

1. determine the number of data to use;
2. provide bendWeight and memWeight, default values are 1.0;
3. run and visualize eigen modes
