Tokamak TerrainMesh grab Terrain Mesh Buffer
Posted: Wed May 18, 2005 2:17 pm
Hi,
I am making my game using Tokamak for physics and I am with difficulty to do with that the tokamak creates a land starting from his mesh-buffer. Somebody would know how to tell me a solution for this.
Here this my current integration class:
EDITED: This code work 100% correct!!
