Primitive ordering

Turn depth stenciling or depth buffering on, it should clear that problem up.

Well I set EnableAutoDepthStencil to true, and AutoDepthStencilFormat to D3DFMT_D16. It now comes up with this very odd screen. Here''s another screenie.



I really have no idea what is happening here.

Did you turn the Z buffer on?

SetRenderState(D3DRS_ZENABLE, TRUE);

1) Make sure you specify D3DCLEAR_ZBUFFER for your IDirect3DDevice*::Clear(..) call.

2) Check that the near clip plane of your projection matrix is greater than 0 (higher is better - improves the linearity of Z space in the Z buffer).

3) Likewise, check that the far clip plane of your projection matrix isn''t stupidly high given the units your scene uses (i.e. if you''re using 1 unit = 1 metre, don''t have the far plane at 1,000,000).

4) Don''t fiddle with the DEPTHBIAS render states unless you need to.

Yes, I set D3DRS_ZENABLE true. I tried clearing the ZBuffer at the beginning of each frame but that just stopped anything from being displayed at all.

Wait, its fixed.

All I had to do was set the ZBuffer clear depth to 1.0f. It now renders perfectly.

Thanks a million to all who helped
