Thanks for reading this. I'm a graphic artist I'm trying to get a functional notebook for exporting a superellipsoid object out to a ..dxf format. I can produce the object in Pov-Ray and paste it into my work as a graphic file but I would like to be able to manipulate it directly in a 'manageable' program such as make use of .obj and .dxf files. the pov source code says: * Superellipsoids are defined by the implicit equation * * f(x,y,z) = (|x|^(2/e) + |y|^(2/e))^(e/n) + |z|^(2/n) - 1 * * Where e is the east/west exponent and n is the north/south exponent. what that means I can't imagine, the objects in Pov are pre-computed and it's always been nice to just be able to type the code as : superellipsoid {<3, 3> pigment { Red } scale 2} hit 'render' and out it pops. this makes the shape I desire as at http://mywebpages.comcast.net/sdbennett/stuff/SUPELLPSoid_Example.jpg I can then duplicate and manipulate the object, but POV lacks a lot of the options I like now in other programs such as Bryce and Cinema 4D, so I want this object. Can someone help? My wife has a copy of Mathematica at Vanderbilt but I'm not able to really fiddle with it much and that's all I can do is fiddle, I'm not any good with math at all, I just need this 'simple' object. Thanks in advance for your help, I have finally managed to export objects to .dxf after what took forever for me to figure out the program. Thanks again I appreciate and admire your expertise.
