N-Patches on Radeon® 8500
|
|
|
The Radeon8500SimpleNPatch sample is a simple application which illustrates the usage of the Direct3D API to turn on N-Patch tessellation and control the order of interpolation on DirectX 8.1. The order of interpolation for normals and positions can be controlled independently. The level of tessellation may be incremented or decremented interactively with the up/down arrow keys.
