Please recommend a program that can build a graphic of a 3d function and save it to some vector file format (SVG, EPS/PostScript, WMF etc.) I found only Madagascar software, it is free, but it was made for Linux and to make it working with Windows I need to build/compile it, but I can not. :( There is no just a link to download a Windows version.
Are there any other software (preferably free or with a free trial period) to draw a 3d function in a vector format?
Thank you.
