Hi, a) when a ContourPlot[] is transformed into a Graphics[] object the polygons are not convex and Mathematica can't render non-convex polygons in 3d with out some additional packages ... b) if you can live with the contour *lines*, you can say ll=Cases[ Graphics[ContourPlot[Sin[x*y],{x,0,Pi},{y,0,Pi}]],_Line,Infinity]; Show[Graphics3D[ ll /. Line[pnts_]:> Line[Append[#,0] & /@ pnts] ] ] Regards Jens "Jan Schmedes" <jasch at crustal.ucsb.edu> schrieb im Newsbeitrag news:dspfv0$cgo$1 at smc.vnet.net... | dear group, | | assume i have two contourplots. now i want to display them both in 3D on | the surface of a cube, e.g. one projected on the front side and one | projected on the top. How could i generate such a plot (or more generall | projected on a given plane, say z=const, in 3D)? | | thank you!! | | jan |
