[Chimera-users] Nutate or lemniscate program to scenes/animation?

[Hurt, Darrell (NIH/NIAID) [E]]

Hi Conrad,

This motion is very similar to what I was imagining, but it is not
precisely there. Although the object wobbles, what I see is a precession
about the Z axis. It takes 4 cycles of this motion to return a given point
to its starting position. A true nutation would return a given point to
its starting position after one cycle.

The difference can be seen in these two contrasting Wikipedia entries:
http://en.wikipedia.org/wiki/Precession
http://en.wikipedia.org/wiki/Nutating_disc_engine

Thanks for helping me!

Darrell
