~~Jriegel~~ 2010-01-08 16:46 administrator ~0000129	I use it at the moment all the time... I need more information. You have the latest trunk?

wmayer 2010-01-08 20:29 administrator ~0000130	1. New document 2. Insert Robots > Kuka IR500 3. Create trajectory 4. Select both and run Simulate a trajectory => Crash in Trajectory_Composite::Pos() because "traj = vt[vt.size()-1];" is wrong if vt is empty. The methods * Trajectory::getLength * Trajectory::getDuration * Trajectory::getVelocity have probably the same problem.

~~Jriegel~~ 2010-01-09 08:25 administrator ~0000131	Ahh, I never tried to simulate a empty trajectory ;) I fix it! Thanks

wmayer 2010-01-09 09:25 administrator ~0000132	So far there exists no method to query the size of "vt" but checking the path length with pcTrajectory->GetPath()->PathLength() does pretty much the same. So, if the length is 0 an empty placement can be returned. The implementation can look like this: Placement Trajectory::getPosition(double time)const { if (pcTrajectory && pcTrajectory->GetPath()->PathLength() > 0.0) return Placement(toPlacement(pcTrajectory->Pos(time))); else return Placement(); } The same applies to the other questionable methods I have listed.

wmayer 2010-01-17 12:29 administrator ~0000150	This bug is still not properly fixed. When inserting exact one position the crash sill occurs.
