   Interface Question
  I goin to make a Interface for my game with power display and so on. I want to use sprites is that the right way ? At the moment there is one problem that i have: i want to render the interface as last because it has to be over all the 3d stuff but if i do so the 3d matrices are allready set how can i set them back to 2d ? A little example please.Greetsflery 
  I think for this kind of interface, people normally use textured quads, but I don''t see why you can''t use sprites. And what do you mean set the matrices to 2D? Do you mean setting an orthagonal projection matrix? ;  i want to set the matrix like they are without perspective matrices. Where the coordinates are just defined by the pixels of the resolution (x,y). ;  You may want to look for transformed vertices, D3DTLVERTEX.If you need 1-to-1 pixel mapping you have to make some adjustments though (there''s a doc in the MSDN somewhere, about 1-to-1 pixel to texel mapping). ;  Instead of using an orthographic projection, just use RHW. Does the same thing and you don''t have to worry about any projection matrices. ;  "just use RHW"a litte more information please
