    Am I right that Voodoo had no early depth test and thus triangles are textured even if they are completely obstructed?

      If you draw front to back that could handle some of that - it does have a Z buffer.

        Without an early Z test that would still do all the same calculations only to discard the fragment when it would be written to the frame buffer.
