v4 v5 12 12 13 13 I have just returned from Dublin where I saw the bridge where WR Hamilton scratched his equation (not that this is important to the maths). When implemented as a quaternion, the rotation matrix about X for an angle A is 14 15 `q = [cos(A/2), sin(A/2), 0, 0] {written as qw,qx,qy,qz}` 16 14 {{{ 15 q = [cos(A/2), sin(A/2), 0, 0] {written as qw,qx,qy,qz} 16 }}} 17 17 The euler angles are [A,0,0] BUT the matrices are: 18 18
