Hi,
Sorry for late reply i thought i will not get any replies on this one, but here`s what i need it for is to study light propagation across different mediums one of this is to study Photoluminescence and some others is to study how light propagates in a normal room and also to study different wavelength behaviours such as ultra violet light ray absorption and emission these are and there are many things i want to use this sort of light simulation for and there is another thing which i noticed is that when i composited these time of flight images they give much more realistic and natural looking light even though they are just demos.
I hope this helps.
