Isosurface polygonization

Abstract:

In the final chapter, we cover how to go from an implicit representation back to a triangle mesh. Since the methods in Chaps. 16 and 17 produce implicit surface representations, isosurface polygonization is essential to complete the reconstruction pipeline. We focus on the popular cell-based approaches where the volume is split into (typically cubical) regions and a polygonal approximation to the surface is computed for each cubical cell. The most famous of these algorithms is the table driven Marching Cubes algorithm. However, we also discuss the more recent dual contouring methods which arguably produce nicer meshes because they have more flexibility with regard to vertex placement.
