I don't get a problem but I have a different graphics card. But increasing the PlotPoints to 100 is the brute force method. It is slow and rotating the image with the mouse is very slow. It is much better to keep the PlotPoints relatively low and use MaxRecursion instead. Compare the two following plots. Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> All, MaxRecursion -> Automatic, ImageSize -> 800] Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> All, MaxRecursion -> 3, ImageSize -> 800] -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ "karsai" <karsai at dmi.u-szeged.hu> wrote in message news:g9t6qq$jd1$1 at smc.vnet.net... > If I run the statement like this: > Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}] > the graphics is fine. > > But if I want to increase the quality using greater PlotPoints, after > a value > > Plot3D[Sin[5 (x + y)], {x, 0, 2 Pi}, {y, 0, 2 Pi}, Mesh -> None, > PlotPoints ->100] > > the graphics contains many worg polygons > > Have somebody seen such problems yet? > > Thanks, > > Janos >
