Rendering to a texture on the ATI
Rage128 and Rage128 Pro with Direct3D
|
|
|
The R128DX7RenderTexture sample program uses the ATI Rage128 and Rage128 Pro to render an image into a texture, and then uses that texture to feedback onto itself. Figure 1 shows R128DX7RenderTexture in action, showing how to use this method to create a feedback blurring effect.

R128DX7RenderTexture first renders an image (in this case a logo) on to a texture surface. It then uses the image from a previous rendering, but with slightly scaled and rotated texture coordinates, and composites it onto the current image to get a blurring effect.
