PN Triangles on Radeon® 8500
|
| |
The PNTriangles_Tutorial sample is a simple
application which illustrates the usage of the OpenGL
PN Triangles extension to turn on PN Triangle tessellation
and control the order of interpolation. The order of interpolation
for normals and positions can be controlled independently.
The level of tessellation may be incremented or decremented
interactively with the +/- arrow keys.
