Function for setting up the random seed.

Post by jalih »

Sometimes it would be useful to be able get the same random numbers for every run.

This one came up when porting Simple raytracer example with photon mapping to Hollywood. There is a part where there is a need for getting the same "random" photons for every run, that is every time user drags objects in scene lighting is recalculated.
