MeshValmet is a tool that measures surface to surface distance between two triangle meshes using user-specified uniform sampling. Thus, user can always choose finer sampling level to calculate errors in order to gain more accuracy in the "error space", or sparser sampling to achieve speed requirement and get a general feeling of error distribution over boundaries. Analyze meshes with this tool.
MeshValmet Features:
1. Use point to triangle closest point distance
2. User specified uniform sampling
3. Space subdivision algorithm, fast computation (avoid brute force)
4. Run in a batch, pipelining of statistical analysis
5. Compute the approximate volume of shape diferences
6. Provide histogram and statistical information
7. 3D visualization of surface distances
