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
