Hi, everyone I would be thankful if someone can help me on this problem: I am using Mathematica 6.0 and it introduces new graphical capabilities that is not compatible with ver. 5.2, I could extract generated mesh data from a Plot3D for further manipulation using for instance the following code: p=Plot3D[Sin[x] y, {x, 0, 4}, {y, 0, 4}] p // FullForm (* to see the structure of p *) p[[1, 1]] (* a list of mesh points in p *) now in ver. 6.0 I cannot exctract mesh data from a Graphics3D object especially when used with built in commands like Sphere[...] like this: g = Graphics3D[Sphere[{0, 0, 0}, 1]] g // InputForm (* !!! no useful output to extract mesh data !!!!*) thank you in advance Ham Sha
