Hi,
I am writing a flight simulator in opnegl -- I am improving my
Terrain Generator and I am confronted with a design decision:
I (as many I am sure) generate a terrain from a height map which is an
image. The whiter the pixel the higher in elevation.
I have implemented a VBO (Vertex Buffer Object) for Triangle_Strip,
and I am not sure if I should add to the buffer the Normals. Would
there be a point as they are pre-calculated? Would the only point be
to alter them (ie: bump mapping)? I suppose I could add texture co-
ordinates.
Does anyone know standard practice in openGL of how much to add to the
Buffers to help computation (ie: traffic flow) since Buffer Objects
are stored graphics card side.
Thanks so much.
