Gimbal lock

[Rudity]

Id say the smartest way of fixing it is preparing for it ahead of time.
Like setting up your rotation orders to what he's going to be doing in the shot.
Also having an extra controler for a wrist incase the main controler gets gimbal lock.

thats my tip. :)
Just prepare for it.

you can always create an extra gimbal control on top of your normal control and assign a different rot order to it. so you have your normal control (hich is parented to the extra control) good for 2 axis, and the extra for the third rotation.

yep.. rotation orders will help greatelly in preventing Gimbal.. though of course, not getting rid of it completelly..

Like Rudity mentioned.. having an extra controller will help prevent gimbal altogether.. though that means that you have to select an extra controller... cons and pros

Has anyone here tried using quaternion interpolation to help with this? I notice that there's an interpolation setting in the preferences that has popped up in 4.0. Are there issues with going this route?

IMO quats are a bear to animate with and they give you/me unpredicable function curves

[mark_wilkins]

A bear how? Is the interpolation unpredictable? I had the impression that when using this feature in Maya you still keyed in Euler space and it just converted to Quaternion space to interpolate. Am I wrong on this?

I'm not advocating using this feature, I just don't know much about how it works in practice.

I recall it screwing up inerpolation and the tangents on my function curves did not give me uniform results. I only played with this feature for 10 or 15 minutes and was not liking the results so I always keep it on Euler...

I may give it another go just to document what was wrong...


...I prefer Euler, since our game engine converts it to quats anyway... :)

[Rudity]

I tried to understand Quaternion Interpolation.
I think I still need to try a bit harder.

I think im gonna give it a try and figure it out.

O hey mark I ordered your book.:buttrock:

[mark_wilkins]

thanks rudity!! :D

[jelloshotsrule]

how does one change the rotation order? and how does it actually work?

thanks. :)

[mark_wilkins]

rotation order is an attribute of a transform.
