I have “glext.h”, and GL_TEXTURE_3D is defined in the header file. The problem is, is when I try to Texture my Image using 3D, not 2D, it does not like the function glTexImage3D. I checked in my header file and it is in there, but my compiler can’t find the function. Also, the function GL_TEXTURE_3D is found by the compiler, but not glTexImage3D. Why?
error C2065: ‘glTexImage3D’ : undeclared identifier
