bwfirt is a framework for benchmarking ray tracing kernels in the context of a realistic light simulation application. The most important capabilities tested here are: fast ray shooting and visibility functions for incoherent mono-rays (no bundles), numerical robustness, and small memory footprint. The framework implements a simple pathtracer to generate rays with a real-life distribution. Developers can easily plug in their cores to the framework, which then compiles the output images, running times, and memory utilizations of the different kernels into a PDF, providing a clear comparison.
hey dave. sorry to come back to you so late.. the sf-forums or the mailing list would have been faster--
which version where you running, and did you try to develop an image (doubleclick or key e)?
also a backtrace to your crash would have been helpful, maybe along with a test file which causes the crash, for me to reproduce it.
