Say, I want to fill a sphere uniformly with random dots; the logical way to do that in r,theta format; otherwise to make a sphere, you'd have to do some heroic math on the three dimension (or is there some quick-n-dirty formula that can do it in one flop, that they don't tell us high school (and Tech School, don't forget!) ?
Either way. I don't want a uniform sphere - more like density through the center looks like a bell-shaped curve, i.e., denser in the middle?
It's got to be computable, maybe with iterations, but that's what I do best! I just have no idea what the algorithm would be.
What I'm up to is I have a 3-d drafting program and I want to approximate a translucent ball effect. I can enter coordinates by copying the output and paste it into the command line to automatically place n dots. ;-)
