is there a way to visualize 3D normal distributions?

Hi all, How do I visualize a contour of a tri-variate normal distribution? I just like to see the ellipsoid very much. I hope there is a easy way or existing method in R.
The misc3d package includes a function for 3d contour plots; that should do what you want.
is contour3d really necessary or could you just plot ellipsoids? (library(rgl); demo(shapes3d)) -- still a little bit of figuring to do, but this should get you most of the way there. Ben Bolker
