Tweening quaternions

[captainlardnicus]

Hi, I've been playing with a gyroscope/compass/accelerometer libraries (namely, "fulltilt") and the data I'm getting does not match the frame rate of the device.

 

Normally, I would rely on TweenMax to smooth things out by just adding a tween every time it updates, but all the information I can see about tweening quaternions in TweenMax relates to the Flash plugin.

 

Has anyone animated (slerped?) quaternions with the HTML5 version of TweenMax?

 

 

Thanks!

Maybe I just have to bite the bullet and average the quaternions...

Yeah, we do have a QuaternionPlugin for ActionScript that could be ported to JavaScript. It does SLERP. You're the first person to ever request it. There are several other tools and enhancements we have in the schedule that we're working on, and QuaternionPlugin is pretty low on the priority list due to the lack of interest out there, but if you really need it for a project and want to contact us about hiring us on a consulting basis to knock that out sooner, feel free to PM me. Or take a look at the ActionScript one yourself and create a JS plugin.

Thank's Jack, I'll take a look!
