Benchmarking Ray Tracing for Realistic Light Transport Algorithms

bwfirt is a benchmark to test the performance of ray tracing kernels in the setting of physically based light simulation. The most important issues are:


Please find a short summary about and instructions for bwfirt in this pdf file.


Example Output

An example pdf file generated by bwfirt can be found here. It contains all relevant information about the system, the compiler, the test scene and the measured performance of the ray tracing kernels.
