Bicubic Subdivision-Surface Wavelets (Image 2)
Caption:
Subdivision surfaces are limit surfaces that result from continual refinement of meshes. Wavelets are mathematical functions that allow us to coarsen meshes and retain the detail between the original mesh and the coarser version. We have developed a new wavelet scheme that complements a known subdivision method called "Catmull-Clark" subdivision. This illustration shows our method when used with a very complex surface. The general idea is to use the wavelet scheme to reduce the number of elements describing the surface, and then use the complementary subdivision method to reconstruct the surface in the best way.
