Giacomo,
Need to use for the 360 animations to get the correct projection, plus
it does the 3D in one step.
Plus, rendered using Tachon per frame ~ 30 sec, using Tachyon-Optix
~0.5 sec per frame.
The following link will take you to an animation that shows what comes
straight out of using Tachyon-Optix (with omniprojection and 3D turned
on) along with the Movie Generator. Though I do combine the frames
together using ffmpeg myself to get it into mp4 format, where can get
much better compression etc than the default with the Movie Generator.
