Raw Normal View History

A batch of changes that have piled up: - Cleaner build system organization (1 SConscript file per directory instead of a single huge file) - Robustness improvements to the KD-tree construction code (now does a better job at handling degenerate triangles) - Switched to an epsilon-free KD-tree traversal loop using Havran's T_{AB}^rec algorithm - Generalization of the KD-tree construction code (now supports plugging in arbitrary tree construction heuristics) - Addition of some utility code (LRU cache, adaptive Gauss-Lobatto quadrature, etc.) - Generic dense matrix class that supports arbitrary dimensions - Pixel traversal within image blocks now uses a space-filling curve ordering - Added support for several noise functions from PBRT - Cleanups of various top-level interfaces (Luminaires, Phase functions, BSDFs, Participating media, etc.) - Robustness improvements to the participating media code (faster + now does a better job at dielectric boundaries) - Added a basic tonemapping utility (can be invoked via mtsutil)
