A variety of applications need to compute a surface mesh from a set of discrete
sample points obtained by some scanning device, or generated by some scientific
simulations. A mesh hierarchy either for multigrid methods or mutiresolution
modeling can be created from such samples by first generating a sample hierarchy
and then computing surface meshes from them. This approach preserves geometric and
topological features automatically and avoids self- intersection, a major concern
in the edge collapsing methods used for mesh decimation. We introduce the sample
shufIling technique to create the sample hierarchy. It deletes and repositions the
sample points so that the triangles have bounded aspect ratio in a resulting mesh
out of them.
