Bounding of displaced parametric surfaces

Bounding of displaced parametric surfaces

Bounding of displaced parametric surfaces is a common use for tessellation in interactive and real-time rendering. An efficient normal bounding technique may be used, together with min-max mipmap hierarchies and orientated bounding boxes. The bounding technique can be used for different types of culling, ray tracing and to sort higher order primitives in tiling architecture. Bi-cubic Bezier patches may be used as primitives and known algorithms may be used for translating Catmull-Clark subdivision surfaces to such patches.
