A Meshing Scheme for Efficient Hardware Implementation of Butterfly Subdivision Surfaces Using Displacement Mapping
Overview A common bottleneck for high performance graphics systems is the transfer of millions of triangles from the CPU to the graphics pipeline. Displacement Mapping is an effective technique for encoding high levels of detail of surface models through the utilization of coarse triangle meshes together with displacement maps. This technique can be employed to reduce the communication requirements between the CPU and the graphics pipeline. This paper presents a new adaptive subdivision scheme in which the curvature of the mesh together with the displacement map information is considered. This paper presents a hardware architecture for the implementation of this proposal. This hardware is an addition to the standard pipeline in order to achieve a displacement map rendering pipeline.
