Euler Angles
roll: 0.0 pitch: 0.0 yaw: 0.0
Quaternion
w: 1.0 x: 0.0 y: 0.0 z: 0.0
Tip: set Pitch close to 90° and try changing Roll and Yaw — notice how the Euler panel loses a degree of freedom (gimbal lock), while the quaternion panel doesn't.
Watch how a plane and its normal vector are reoriented in 3D space, using two different rotation representations.
