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.
