Question #671141 on Yade changed: https://answers.launchpad.net/yade/+question/671141
drasszkusz gave more information on the question: 1. and 2. and 3. questions solved. Not really understood quaternion before. drum=O.bodies.append(geom.facetCylinder((0,0,0),radius=1,height=2,orientation=Quaternion((1,0,0),pi/2),segmentsNumber=10,wallMask=4,color=(.3,.3,.3))) RotationEngine(rotateAroundZero=True,zeroPoint=(0,0,0),rotationAxis=(0,1,0),angularVelocity=omega, ids = drum) One question remained, if I use orientation=Quaternion((1,0,0),pi/4) then how to calculate the rotation axis of the Rotation engine?
