create a basic image background

One way is to create an XYZRHW quad full screen and texture it with your image.

I vaugly remember someone talking about this method. What about plain old sprites though? Don''t tell me they have taken them out of DX version 9? Have they?

Some video cards don''t support textures beyond 256x256 -- just texturing the quad w/a fullscreen texture won''t work in this case.

Good point Fyhuang. Mangine, sprites are still available. You can use them to do the same thing. If you want to make your screen compatible with almost all 3D hardware out there, then break the image into 256x256 pieces and display them in sprites.

I think you want to turn all filtering off if you do that and you might consider using an orthogonal projection. Actually, that may only be useful if you use 3D space (instead of XYZRHW).

Sprites are still in DX9, and they are improved slightly from DX8. Use D3DXSprite and you should be fine. In case you don''t know, the D3DXSprite is just a textured quad...it prevents you from having to setup the vertex buffer yourself.

Happy coding.

Now I''m going to have to create a texture from my jpg. Any good tutorials on creating DX Textures?

D3DXLoadTextureFromFile() (or whatever its called) will do the trick. Otherwise you''ll need to decode the JPEG yourself...
