Dear Noga, for the following code to work you will have to install the IMTEK Mathematica Supplement (IMS) from: http://www.imtek.uni-freiburg.de/simulation/mathematica/IMSweb/ Please note: There is also a mailing list at: http://elmo.imtek.uni-freiburg.de/mailman/listinfo/ims Now the code: << DiscreteMath`ComputationalGeometry` Needs["Imtek`MesherUtilities`"] data2D = Table[{Random[], Random[]}, {25}]; delval = DelaunayTriangulation[ data2D ]; Needs["Imtek`UnstructuredPlot`"] imsUnstructuredMeshPlot[ data2D, incidents, PlotRange -> All ] vals = Table[Random[], {Length[data2D]}]; imsUnstructuredContourPlot[ data2D, incidents, vals ] If you can generate the mesh this works also in 3D - we use it for Finite Element and other PDE stuff.
