Hi Experts, I work up about 25000 datas of one surface. To show these datas {x,y,z} I use a package of the following book: "Mathematica Graphics: Techniques and Applications" TELOS/Springer-Verlag Publishers, 1994 ISBN 0-387-94047-2 To load this package... Needs["ExtendGraphics`SurfaceGraphics3D`"]; and to show the Surfaceplot... ListSurfacePlot3D[xyAsti]; xyAsti is a List of Datas of this kind: xyAsti={{x1,y1,z1},{x2,y2,z2},...} To show this Graphic the computer needs a long time. My question: Is there any wah to speed up this kind of plot or to speed up generally ListPlot3D? With what precision does Mathematics 4.0 calculates thes Plots? Can I reduce this precision in any way? To reduce the datas make me loos informations about the surface!!! Probably anybody can give me advice!? Thank you, Martin
