Jan, Unfortunately, it looks like the Mathematica ConvexHull function is limited to 2D problems. You can, however, download "qhull" for free at: http://www.geom.uiuc.edu/software/download/qhull.html Qhull can handle convex hull problems with three (or more) dimensions, and can calculate volume. -JL Jan Schmedes wrote: > Dear all, > > i have a set of points in 3D {{x1,y1,z1},...,{xn,yn,zn}} and i want to > calculate the volume of the convex hull of these points.
