My comment is in thre parts: 1. My SS will be 5346 for ever on XP. If my actual XP burns I have alternatives: another XP Home, another XP Pro. and one Millenium. An acceptable alternative could be some updated Plugin installable on 5346. 2. The "dead stone Maxima" is not worth a comment. If it's not possible to copy paste the Handbook demo and adapt to other stuff: Draw3D => recycle bin. 3. "Crappy 3D Maxima" speaks by itself: No user mesh density in both X/Y directions. No user mesh color. The actual default gradient color is non-sense. The "non-sense gradient color" is blind to color blind person(s) and "3D flat person(s)". In short: 3D Maxima is not even pregnant of the 3D first essentials.

Works for me even with the most recent SMath version. "do as much as possible" is a very individual thing. Does it include using a clean SMath with Maxima portable installation? Please note: The plot shown by Jean is a 3D Plot Region provided by the 3D plot plugin. It is NOT related to Maxima. |

That's right: NOT a Maxima, just a plot region like X_Y In fact, it is NOT a 3D, simply a 2D parametric. The function in "Draw3D" is misleading: it is a symmetric Gaussian. Levels are pure circles. The attached demonstrates some useful "contour" tips. Thanks Martin. Contiur QUICK.sm (25kb) downloaded 33 time(s).
