quaternion
Either a string that represents space separated 4 coodinates or a THREE.Quaternion
instance.
Examples below set the rotationQuaternion
prop to (x, y, z, w) = (0.91, 0.23, 0.34, 0.88)
.
<vgl-group rotation-quaternion="0.91 0.23 0.34 0.88" />
<vgl-group :rotation-quaternion="new THREE.Quaternion(0.91, 0.23, 0.34, 0.88)" />
