1. Ambient Occlusion for Particles Encode global information in textures for use during rendering

2. 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 11Fireball 11

3. Silhouette Edges 8

4. Silhouette Results Requires no precomputation time Impact on performance is only 2-5% for most applications. Data agnostic Movie - Time Varying Foam Data setTime Varying Foam Data set
