Nutate or lemniscate program to scenes/animation?
Hi Chimera folks! I love, love, love the new scene-based animation! I know that it is still under development, but it is fantastic! And the "Animation" utility panel is easy to use and understand. I love the "Rock" and "Roll" "Actions" available in the Animation panel. That goes a long way to making movie-making a point-and-click affair! I would like to suggest or propose one more "Action" in addition to "Rock" and "Roll". It is "nutate" or "lemniscate". It is basically a "rock" in both the X and Y planes at the same time. I think that it can be coded relatively simply with a cosine function about the X axis concomitant to the sine function about the Y axis that is driving the current "Rock". You can see an example of what I'm talking about here: http://youtu.be/55_cmJLe3Is Also, if I could, I would also suggest or propose that the "Rock" and "Nutate/Lemniscate" have a single parameter to control the "width" of the rock or nutation/lemniscation — maybe choices of 15, 30, 45, and 60 degrees or a free-form entry. Thanks for everything you do!

Can you try the following command in Chimera and see whether it produces the "nutating" or "lemniscating" motion (I love those words): rock x 5 cycle 180 ; wait 45 ; rock y 5 cycle 180 Obviously the initial 45 frames needs to be excised, but is the motion after that the type of motion you described?

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!

Hi Darrell, I added a precession option to the Chimera turn and roll commands that I believe performs the motion you are looking for. I added an example called "wobble motion" in the Chimera animation gallery. http://www.cgl.ucsf.edu/chimera/animations/animations.html The new option specifies the angle between the rotation axis and the precessing axis, for example, roll precess 20 Conrad will add an action to the Chimera Animation dialog to incorporate the motion in animations.
