Drawing

Look-up "Double buffering" in the articles and resource. You can also use the vsync to stop the flickering, but I like double buffering better. basically, you draw to an off-screen bitmap and then copy this bitmap to the screen. You didn''t include your os/language/api so I can''t give you an example. Just check the articles on this site or google it.

I am using C++. Here is the code I am using

f_pDirect3DDevice->BeginScene();
DrawBox();
f_pDirect3DDevice->EndScene();

f_pDirect3DDevice->Present(NULL, NULL, NULL, NULL);
  

Here is the DrawBox Function.

void DrawBox()
{
	f_pDirect3DDevice->SetVertexShader(D3DFVF_PANELVERTEX);
	f_pDirect3DDevice->SetStreamSource(0, g_pVertices, sizeof(PANELVERTEX));
	f_pDirect3DDevice->DrawPrimitive(D3DPT_TRIANGLEFAN, 0, 2);

}
  

The box draws fine, but it flickers. Any ideas?

Did you forget: f_pDirect3DDevice->Clear(...);

Or are you using MFC, if so you must tell MFC not to erase the background.
If its none of this, gives us more information.
