I know this is a simple question, but... I wrote a small c program which draws a cube with 2 opposing sides removed to make it "hollow," and which lets you move around inside the cube. I use "makeobj()" to define the cube and "polf()" to draw each face. It looks correct from one side, but when you look at it from the opposite side, the computer still draws the faces in the same order of overlap, so it does not look right. Does this have something to do with zbuffering? I'm using a 3020, by the way. Any help would be appreciated.
