Hi all,
I am using a script where the .st have to wait particle stabilization before
starts its TranslationEngine+ RotationEngine.
For this I am using in O. engines:
...
CombinedKinematicEngine(ids=rod,label='combEngine', Dead=True) +
TranslationEngine(translationAxis=(0,0,1),velocity=vel) +
RotationEngine(rotationAxis=(1,0,0), angularVelocity=angVel,
rotateAroundZero=True, zeroPoint=(0,0,0)),
PyRunner(command='checkUnbalanced()',iterPeriod=500),
...
def checkUnbalanced():
print "Unbalanced: ",utils.unbalancedForce()
if utils.unbalancedForce()<0.22:
O.engines=O.engines+[PyRunner(iterPeriod=1,
command="updateKinematicEngines()" ),
CombinedKinematicEngine(ids=rod,label='combEngine', Dead=False ) +
TranslationEngine(translationAxis=(0,0,1),velocity=vel) +
RotationEngine(rotationAxis=(1,0,0), angularVelocity=angVel,
rotateAroundZero=True, zeroPoint=(0,0,0))]
transEngine, rotEngine = combEngine.comb[0], combEngine.comb[1]
The problem is that the stl loses its center and the rotation is around another
zeroPoint (perhaps the global zero point, not the stl zero point).
Any idea of what is wrong?
Thank you
Luis
