Projected Spotlight and Dynamic Shadow Textures on Radeon®

Figure 1 - Projected spotlight and dynamic shadow map   Figure 2 - Dynamic shadow map Figure 3 - Spotlight map

The sample RadeonSpotlightShadow uses SetRenderTarget to generate a dynamic shadow map texture rendered from the light point-of-view. It uses automatically generated camera-space position coordinates to apply both the shadow map and a spotlight texture to scene objects. Both textures and a color factor ambient term can be applied in a single pass using the Radeon® multitexture stages. Figure 1 shows the applied projected textures. Figure 2 shows the dynamically generated shadow texture, and Figure 3 shows the spotlight texture.
