Detailed Description

NOTE: Class Quaternion will always keep itself normalized, since we are using Quaternion for rotation only. Similarly, only functions and operators necessary for performing rotations are implemented.

Constructor & Destructor Documentation

Core::Quaternion::Quaternion ( const Matrix &  matrix )

explicit

construct a quaternion from the given rotation transformation NOTE: if the matrix is not pure rotation, the result is undefined NOTE: the matrix should be column major
