摘要: One of the main challenges in global illumination is rendering scenes with millions polygons and megabytes textures. Combining processing power memory multiple processors or workstations to render these complex an attractive proposition but interactions between data introduces a significant amount communication. Data locality methods may improve cache coherence access by finding optimal partitioning, re-ordering computations, replacing geometry simplified image-based representations. We review different focus on local caching radiance values. present results implementation ray tracing program Radiance.
