Re: [osg-users] quaternion to euler
Hi Rabbi, You can start from osgAnimation::UpdateTransform callback, change the euler to quaternion or ineherit to add quaternion then adjust the method needLink, link, update to use your new quaternion. Then set your new UpdateTransformQuaternion callback to your Transform The code are in src/osgAnimation/UpdateCallback.cpp Cheers, Cedric On Tue, 2009-06-30 at 20:22 +, Rabbi Robinson wrote: > Hi, > > Yes, I am using that.

Re: [osg-users] quaternion to euler
Hi, Yes, I am using that. I will give it a try. Strangely there is "euler" in the animation but not more useful "quaternion". Can you show me how to add it? Thank you!

Re: [osg-users] quaternion to euler
Hi Rabbi, Which animation are talking about ? do you refer to osgAnimation::UpdateTransform callback ? If you need quaternion instead of euler, it's very easy to add a new UpdateTransform that could manage quaternion.

I think there is a constructor in osg::Ang() that takes a quaternion as well. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=14671#14671 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
