Spatial Directional Radiance Caching
We present a new approach for accelerated global illumination computation in scenes with glossy surfaces. Our algorithm combines sparse illumination computation used in the radiance caching algorithm with BRDF importance sampling. To make this approach feasible, we extend the idea of lazy illumination evaluation, used in the caching approaches, from the spatial to the directional domain. Using ...
متن کاملPre-convolved Radiance Caching
The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both compute incident indirect light only for a small subset of pixels (the cache), and later interpolate between pixels. Irradiance Caching uses scalar values that can be interpolate...
متن کاملClustered Pre-convolved Radiance Caching
We present a scalable method for rendering indirect illumination in diffuse and glossy scenes. Our method builds on pre-convolved radiance caching (RC), which enables reusing the incident radiance computed at a surface point for its neighborhood. Our contributions include efficient and robust generation of these RCs based on a pre-filtered voxel representation that stores scene-geometry and sur...
متن کاملData Structures for Interpolation of Illumination with Radiance and Irradiance Caching
Irradiance and radiance caching are important algorithms for solving the light transport problem in realistic image synthesis. ey both require geometric search data structures for efficient rendering. Our goal was to improve the caching algorithms by improving these data structures. We have implemented 6 different data structures for irradiance caching, 2 previously used and 4 newly adapted to...
متن کاملQuantifying Temporal and Spatial Localities Due to File System Caching
Modern storage consists of many optimizations along the data path, from the front-end file system cache and disk layout management to the back-end disk controller cache and on-disk caching. Various components generally exploit the temporal and spatial localities of a workload to improve performance. However, how localities of a workload are transformed by each optimization is not well understoo...
