Hello Alexi, You should be able to extend this example to your purposes: coords = RandomReal[{0, 1}, {20, 3}] spheres = Table[{Hue[coords[[i, 3]]], Sphere[i, .1 coords[[i, 2]]]}, {i, 1, Length[coords]}] Graphics3D[GraphicsComplex[coords, spheres]] Kind Regards, Craig On Wed, Jun 4, 2008 at 5:37 AM, Alexei Boulbitch <Alexei.Boulbitch at iee.lu> wrote: > I have a list containing 3D coordinates of a number of points, like this one > > Now comes the question.
