    Class quat

    A quaternion, used to represent rotation.

    // Rotate a SceneObject around the world Y axis
    //@input SceneObject obj

    // Degrees to rotate by
    var degrees = 90 * getDeltaTime();

    // Convert degrees to radians
    var radians = degrees * (Math.PI / 180);

    // Axis to rotate around
    var axis = vec3.up();

    // Rotation we will apply to the object's current rotation
    var rotationToApply = quat.angleAxis(radians, axis);

    // Get the object's current world rotation
    var oldRotation = script.obj.getTransform().getWorldRotation();

    // Get the new rotation by rotating the old rotation by rotationToApply
    var newRotation = rotationToApply.multiply(oldRotation);

    // Set the object's world rotation to the new rotation
    script.obj.getTransform().setWorldRotation(newRotation);
