V-REP crashes on stopping simulation

Post by prvn16 »

Hi,
I have installed latest VREP-EDU 3.1.0 on Windows 7.
Some of the sample programs run fine on simulation start, pause. However they crash when I press stop simulation button.
I ran through all the example scenes given (ttt files)
Following are the crashing programs with the above sequence (other example scene ttt files do not crash):
blobDetectionWithPickAndPlace
e-puckDemo
ImageProcessingExample
LineTracer-threaded
millingMachine
rosTopicPublisherAndSubscriber
StripeScanner

What is the reason was this crash? How to avoid it?
Is this a bug?
Incidently mooc_example (example 1) of Coursera also crashes.
If I connect through octave remoteAPI, V-REP again crashes when I send simulation_stop(connection), else it keeps working.

Hello Praveen,

you probably have an old graphic card, or an obscure integrated graphic card. In the openGl section of the user settings, can you check Compatibility tweak and see if the problem persists? From the crashing examples you mention, they all make use of the vision sensors, which rely on OpenGl.

If that doesn't help, try to play with the other openGl settings, mainly Offscreen context type or FBO type.

Cheers
