Oops.
I had this problem, the depth buffer was not working in OpenGL BrickDraw3D.
Everything was drawn on top, in order of calling.
I needed to put depth into this attrib list:
GLint attrib[] = { AGL_RGBA, AGL_DEPTH_SIZE, 16, AGL_NONE };
before calling this:
fmt = aglChoosePixelFormat(NULL, 0, attrib);
Figured that out by looking at the GLUT source.
Another bug was the lack of this statement:
glEnable(GL_COLOR_MATERIAL);
Without that, glColor() calls had no effect.
Yet another unsolved bug shows one solitary tube for each brick, and it is
poking up above the top.
But, I am getting closer to a BrickDraw3D with pure OpenGL!
