My problem is not how to insert a 2D plot in a 3D graphics (as you showed very nicely) but rather how I construct mathematically an actual 3D structure that looks like a cloud. > Is there any algorithm producing a distribution of points (x,y,z) (maybe based on a random number generator) or a continuous surface f(x),f(y),f(z) resembling that of a cloud e.g.http://www.google.com/imgres?q=weather+clouds&num=10&um=1&hl=en&clien... > > Thanks a lot, > Dimitris You could try ContourPlot3D of, say, 3 contours of the distributions of a small number of 3D points, as generated by a nonparametric density estimator, which I believe is built in now to Mathematica 8. You could put a low opacity on each surface to give it some sense of impermanence. B
