Ambient Occlusion for Particles

• Encode global information in textures for use during rendering

Ambient Occlusion Results

• Only 10% impact on frame rates as compared to direct lighting only

• Textures only as good as or better than DL only

• Does have a huge memory requirement– Texture compression (VQ, PCA)

• Can be used with shadows• Movie - Fireball 11

Silhouette Results

• Requires no precomputation time

• Impact on performance is only 2-5% for most applications.

• Data agnostic
