Hi all, A friend of mine is using MMA version 3 on a Windows 95 machine. He is having difficulty removing "the jaggies" from his MMA graphics, which are renderings of polyhedra (Graphics3D). I use MMA version 2.2.2 on a Mac, and I have found this method to work very well: I use the pop-up magnification thingy at the bottom of my notebook window and magnify the graphic to 300%. I then force it to render PostScript at 300%, usually choosing "Make Lines Thin" in the Graph menu. Then I return to 100%. The graphic is now nicely anti-aliased. I choose Convert To Bitmap PICT in the Graph menu, and save the graphic to a PICT file. I can then convert this file to JPEG or GIF format for sending with email. It all works very nicely, in fact, I sometimes even use this method on every frame in an animation. However, using version 3.0 on his Windows 95 machine, my friend has had no luck using this technique. I am not sure what to tell him now; I have no experience using MMA on a Windows machine, nor, for that matter, any significant experience using version 3.0. Help!!!
