If you have the surfaces you can use depth-buffering (see opengl for example) or use "painters" algorithm: Draw vertices and surfaces first that are further away from the camera. You can use a binary space partitioning to do this efficiently ...

Web25 de ago. de 2011 · In many cases, 3d hidden surface removal means that when you draw a surface, you also remember the depth of each pixel that you draw (distance from the 'eye'). When you go to draw a surface where a surface has already been drawn, you only draw the pixel if it's closer to the eye than the pixel that's already there.
