Raytracing Prefiltered Occlusion for Aggregate Geometry
Raytracing Prefiltered Occlusion for Aggregate Geometry Dylan Lacewell1,2 Brent Burley1 Solomon Boulos3 Peter Shirley4,2 1 Walt Disney Animation Studios 2 University of Utah 3 Stanford University 4 NVIDIA Corporation Figure 1: Computing shadows using a prefiltered BVH is more efficient than using an ordinary BVH. (a) Using an ordinary BVH with 4 shadow rays per shading point requires 112 seconds for shadow rays, and produces significant visible noise. (b) Using a prefiltered BVH with 9 shadow rays requires 74 seconds, and visible noise is decreased. (c) Reducing noise to a similar level with an ordinary BVH requires 25 shadow rays and 704 seconds (about 9.5× slower). All images use 5 × 5 samples per pixel. The scene consists of about 2M triangles, each of which is semi-opaque (α = 0.85) to shadow rays. ABSTRACT aggregate geometry, it suffices to use a prefiltering algorithm that is We prefilter occlusion of aggregate geometry, e.g., foliage or hair, linear in the number of nodes in the BVH.

Fast Precomputed Ambient Occlusion for Proximity Shadows

We present a new, simple method for storing ambient occlusion values, that is very easy to implement and uses very little CPU and GPU resources. This method can be used to store and retrieve the percentage of occlusion, either alone or in combination with the average occluded direction. The former is cheaper in memory costs, while being slightly less accurate. The latter is slightly more expensive in memory, but gives more accurate results, especially when combining several occluders. The speed of our algorithm is independent of the complexity of either the occluder or the receiving scene. This makes the algorithm highly suitable for games and other real-time applications.

Motivation Screen-Space Ambient Occlusion Screen-space ambient occlusion (SSAO) is a further Methods for non-photorealistic rendering of 3D scenes have approximation of this technique, which was developed by become more popular in recent years for computer CryTek for their game Crysis and its engine. This version animation and games. We were interested in combining computes ambient occlusion for each pixel visible on the two particular NPR techniques: ambient occlusion and screen, by generating random points in the hemisphere cartoon shading. Ambient occlusion is an approach to around that pixel, and determining occlusion for each point global lighting that assumes that a point on the surface of by comparing its depth to a depth map of the scene. The an object receives less ambient light if there are many other sample is considered occluded if it is further from the objects occupying the space nearby in the hemisphere camera than the depth of the nearest visible object at that around that point. Screen-space ambient occlusion point, unless the difference in depth is greater than the approximates this on the GPU using the depth buffer to test sample radius. The advantage of this method is that it can occlusion of sample points. We combine this with cartoon be implemented on graphics hardware and run in real time, shading, which draws dark outlines on objects based on making it more suited to dynamic, interactive scenes due to depth and normal discontinuities, and thresholds lighting its dependence only upon screen resolution rather than intensity to several discreet values. -
