Detailed Description
Gaussian blob.The point Center is the center of a normal probability density of standard deviation StandardDev. The density is radially symmetrical. The blob domain allows for some very natural-looking effects because there is no sharp, artificial-looking boundary at the edge of the domain.
Generate returns a point with normal probability density. Within has a probability of returning true equal to the probability density at the specified point.
