CamSim is superseded by WurblPT.
CamSim is based on the rasterization approach of image rendering. While this makes it very fast, it also imposes severe limitations on the simulation of effects relevant to Time-of-Flight imaging.
WurblPT is a full-featured path tracer instead and does not suffer from these limitations. Simulation quality is much better, at the price of higher computational costs. Furthermore, the code of WurblPT is much simpler and easier to read and adapt since it does not need to accomodate the OpenGL graphics pipeline.
