Process rotations keys to make Euler angles continuous bewtween successive keyframes.

This is done for each keyframe by finding an equivalent set of Euler angles that is closest to the proceeding key. Therefore, the object's orientation at the keyfram will remain the same but the actual angles may change.

This is useful for removing cycles of more than 180 degrees from the keyframes which will result in smoother animation fcurves. This can occur with motion captured data and/or is also useful when converting between quaternion and Euler fcurves.

VBScript Example

' 
' In this example, an FCurve is created on the ZRot param
' of a cone. Then, some keys are created (at frames 1, 15 and 30)
' which are then made continuous. (by removing an extra rotation
' of 360 degrees at frame 15)
'
