Hi, I was reading the book "Texturing and modeling: a procedural approach" to learn how to create tileable worley/cell noise ( so I can use it in the technique described in this thread :P http://www.gamedev.net/topic/680832-horizonzero-dawn-cloud-system) and there is only one thing that it's not entirely clear to me, and that is how to calculate the amount of points that are inside each of the cells using the poisson distribution.
The poisson distribution gives me the probability of a certain number of points being in a cell (given a known average of the amount of points in a cell), but I don't understand how to sample the equation for the cells. In the book they use some kind of number generator with a seed that they get from the id of each cell, but I can't wrap my head around it.
In university I remember having a subject about probabilities and statistics, but the problems were always relatively simple ( 'calculate the probability of...' ) and I've never used probabilities outside of the university classes so now the time has come, and I'm a bit lost.
Any help is appreciated, thanks!
