You may backpack any of the sprites/take scripts without credit. Note that the QuaternionsLib and lite version are dependent on a LUT for trigonometric values.
The QuaternionsLib is a work-in-progress library of quaternion operations. Operations include quaternion multiplication, conjugation, and SLERPing. The QuaternionsLib(Lite) is a complete library for the basic operations. The basic library should contain sufficient content for world-view transformation in rendering. All of the "lite" library is included in the full library. This library is extracted from Gamma Engine.
