Hierarchical Radiosity On Curved Surfaces
Incorporating curved objects into a hierarchical radiosity system typically bears a great disadvantage: the initial tessellation already needs a large number of small polygons because further mesh enhancement is impossible. We will show that improvements in rendering speed and quality can be made by extending the planar meshing of the refinement step to an object-specific subdivision scheme. While keeping the number of input polygons extremely low an arbitrary accuracy of the solution can be obtained.
