Primitive on top

I would think the easiest way would be to disable z buffer drawing, the draw it last. That way everything that you''ve already drawn would remain intact and you could simply draw it on top. Unless you want a 3D mouse cursor, you could also switch to ortho view and draw a simple 2D quad to the screen.

Note: None of this has been done by me. I understand the concepts, but have never been able to complete a 3D game

Always remember, you''''re unique. Just like everyone else.

search the docs for D3DFVF_XYZRHW - this will allow you to set vertices in screen coordinates that are independent of the view transformations. Great for cursors, 2D elements, etc.
