Infos about Render to Texutre in DX >= 8
Author
hi
I''m searching websites or papers about rendering to textures in DX8. i think there must be other ways then ID3DXRenderToSurface.
maybe someone has some infos/urls which sompare different approaches, etc...
I allready did a google search, but most of the stuff i found was for DX7..
thanks in advance

I have a couple of chapters about this in the first book below.
The short answer is that you can create a texture with the correct flags and get the underlying surface for that texture. Then, set that surface as your back buffer and render. There are a few more pieces (such as dealing with the depth buffer and the changing viewports), but it can be done without the D3DX functions.

thanks for the answers!
i bought 3 books last month, so i have do make a little "buy-stop" for now
but a buddy of mine said this is an excellent book. maybe i gonna buy it anyway later.. ?!?
does most of the stuff in the book also apply to DX9?
you mean i should try something like this:
// save back buffer first
dev->GetBackBuffer(..,..,..,&savedBackBuffer);
dev->SetRenderTarget(0,surfaceOfMyTexture);
drawStuff();
dev->Present(..);
// restore BackBuffer
dev->SetRenderTarget(0,savedBackBuffer);
?
kind regards

Yes, the book should apply to DX9 with only very minor changes.
As for your pseudocode, yes, that''s a start. Take a look at the cube map example in the SDK. It should get you started on the basic approach.

Or have a look at my website (www.wolfnight.org): I''ve done a ''Render To Texture''-Sample some time ago. You can download the source (Delphi - but actually not hard to read) in the download-section.
It should also be pointed out that setting the render target causes DX to forget your viewport settings.
