Maarten, you could delete all Line primitives within the graphics expression: g = Plot3D[Exp[-x^2 - y^2]/2, {x, -2, 2}, {y, -2, 2}, PlotRange -> {0, 1}, ColorFunction -> Function[{x, y, z}, GrayLevel[(1 + Cos[50 z])/2]], ColorFunctionScaling -> False, PlotPoints -> 100, Mesh -> False, Lighting -> {{"Ambient", White}}, Boxed -> False, Axes -> False]; Show[DeleteCases[g, _Line, Infinity]] Regards, Yves van der Burgt, Maarten schrieb: > Hello, > > For testing certain image processing methods I want to convert a > Graphics3D object as generated by > > > > my3d = Plot3D[Exp[-x^2 - y^2]/2, {x, -2, 2}, {y, -2, 2}, > > PlotRange -> {0, 1}, > > ColorFunction -> Function[{x, y, z}, GrayLevel[(1 + Cos[50 z])/2]], > > ColorFunctionScaling -> False, PlotPoints -> 100, Mesh -> False, > > Lighting -> {{"Ambient", White}}, Boxed -> False, Axes -> False] > > > > to a raster image.
