   2D map in the 3D screen
  I'm trying to work some 2D into my 3D game.I wanted to make a map that gives a top down perspective of the playing field that svisible while in game with 3D. Does anyone have any good ideas how to do this?   
  Do you mean like a minimap, or just a topdown view of the world? For the second, just create an orthogonal projection matrix (See D3DXMatrixOrthoOffCenterLH)   ;  Expanding on Steve's post, you could either render the map directly to the screen buffer (after the scene's complete) using a smaller viewport (IDirect3DDevice9::SetViewport) or, for more flexibility, render the map to a render-texture target and put this onto the HUD in the usual way.Either way, you need to render the entire scene twice, using different transformation stacks and viewports/render-targets.Admiral
