Hi,
This is the first time that I post the question here. Please point me a direction for the question below. Thanks in advance!
I’m trying to do dot3 bump mapping using OpenGL, where the multi-texturing function is used:
glMultiTexCoord2fARB(GLenum texUnit, TYPE coords)
At the same time, I need to tesselate the textured polygon to render ploygons with holes inside. In this case, I need to use:
gluTessVertex(GLUtesselator* tessobj, GLdouble coords[3], void * vertex_data)
However, I can’t find a way to do both together. I can’t find a way to fit the glMultiTexCoord2fARB(…) function in the GL tesselation routine and vice versa.
Anyone had the similar problem before or has the ideas to get around it? I have an urgent dealine to meet and must sort this out soon. Any comments will be really appreciated.
Many thanks,
Chen
