opengl - PyOpenGL Cube Mapping Textures -


i've tried texture_2d push textures on cube. thats no problem.

but when use texture_cube_map textures aren't visible. black cube.

can me?

a cube map not literal "put texture on cube." kind of texture, separate 2d, 3d, etc texture types.

a 2d texture 2d image use position in 2d space access. 3d texture 3d image use position in 3d space access. cube map set of 6 2d images use 3d direction access. imagine sitting in center of cube. in every direction location on cube. that's color accessing cube map given direction.
