public class RotationTrack3ds

extends Track3ds

Rotation track.

The rotation track control rotation of a mesh around its pivot point. 3D Studio stores the rotation tracks as angular displacements. The first key in the track gives the absolute rotation. The following keys are relative rotations to the previous key. To be useful, the angular displacements must be converted into quaternions. Using quaternion multiplication, the absolute rotation at each key can be calculated.
