WebMesh Decimation ¶ The aim in mesh-decimation is to remove points without destroying the topology and general shape of the mesh too much. In VTK, the decimation, is based on [Schroeder1992]. Fig. 7.2 Mesh decimation seeks to remove certain points. See video. 7.5.3. Mesh Smoothing ¶ In VTK, the smoothing, is based on a Laplacian smoothing … WebPyMesh is a rapid prototyping platform focused on geometry processing.
