William, In this particular case, having control over the camera and lights was key in getting a decent looking image. The process was much like photography. I fiddled with the lights for a good half hour to get what I was looking for. My goal, in the end, was to create some reasonably professional-looking marketing material.
I will look into the new method once I upgrade my sage installation. I am still on 2.8.15 :) and I might not upgrade until 2.10.x On Jan 13, 12:10 am, "William Stein" <[EMAIL PROTECTED]> wrote: > On 1/11/08, Timothy Clemans <[EMAIL PROTECTED]> wrote: > > > > > Could you make the Sage interface to Tachyon have a right handed > > coordinate system instead of a left one? > > It is much better to use the new 3d graphics, which is right handed > and supports tachyon output.
