Ah, sorry, I should have said. Its the fan of the ideal generated by:
{v^2-w-1, w^2-x-1, x^2-y-1, y^2-z-1, z^2-v-1}. Not very complicated,
but of course with 5 variables you can't compute most fans.
I'm going to give a talk in early November on visualizing geometric
objects with associated
I thought I'd mention that using ffmpeg and Sage/singular/gfan/tachyon
I was able to finish the little pilot project I had in mind: taking a
5d Groebner fan, intersecting it with a hyperplane, rotating it in 4d,
and animating the projection into three dimensions. I am still
struggling with the

Thanks very much for this response. ffmpeg looks very useful to me, I
am checking it out right now. It is unclear to me what the overlap is
with mplayer/mencoder. It seems that ffmpeg is somewhat leaner and

It would seem that ray tracing should be a fully parallel task.
Yes, it is, but multicore isn't the issue I think. Images can be split
up into smaller rectangles (i.e. rendering a single image by 4 cores

Thanks Vincent for the information. One reason I am choosing not to
use povray is the license, which I believe is not compatible with
inclusion in Sage.
Btw, the tachyon raytracer does seem to have good multicore support dy
default. Unfortunately it cannot animate. I wish we had someone who
