Quat (struct)¶
The Quat represents a 3D rotation as a quaternion. Quaternions are used within the Xfo type. A Quat can be converted to and from Mat33 as well as Euler types.
/*
** Example: Quat
*/
// create several quaternions
Quat q0, q1, q2, q3, q4;
q0 = Quat(Vec3(1.0, 0.0, 0.0), 0.0);
q1.setFromEuler(Euler(PI, 0.0, 0.0));
q2.setFromDirectionAndUpvector(Vec3(1.0, 0.0, 0.0), Vec3(0.0, 1.0, 0.0));
q3.setFrom2Vectors(Vec3(1.0, 0.0, 0.0), Vec3(1.0, 1.0, 0.0));
q4.setFromAxisAndAngle(Vec3(0.0, 1.0, 0.0), HALF_PI);
