I have a human body 'surface' mesh data.: triangular mesh (vertices, face)What I want to get from this is 'exact-down-sampled' version of the current mesh.Which means.. the processed output mesh should have the vertices that all belong to the input mesh and the mesh data should be in the triangular mesh form..I know there are some surface mesh simplification algorithms, such as poisson surface reconstruction algorithm. But as far as I know, they don't preserve the positions of the input mesh. What I simply want is to down-sample the points and triangulate them.
exact down sampling and re-triangulation of mesh data(non-convex)
