Thanx for all the tips! OK, I tried Tachyon? and the help file works. I also tried rendering some ray tracings as suggested in Tachyon? by constructing t=Tachyon() objects and all works very nicely! Some questions about Tachyon: (1) Is this the same tachyon by John Stone? If so, how is this a

The tachyon raytracing uses the tachyon class, called Tachyon. If you type Tachyon? you will get a help file. Sometimes it is nicer to work more directly work with tachyon, which can be done by creating an instance of that class: sage: t = Tachyon() Then you can explicitly control the camera, l

OOPs, tachyon does work. I tried the following and all is well: x,y=var('x,y') a=plot3d(x**2+y**2, (x,-10,10), (y,-10,10)) show(a,viewer='tachyon') Is tachyon the only 3d viewer on the liveCD then? Also, why doesn't tachyon? give any help? TIA, A. Jorge Garcia Applied Math, Physics and Comput
