V-REP's window WM_CLASS attribute is empty on Linux

The WM_CLASS attribute of the V-REP main window (used by window manager to associate windows with the owning application), is not set. You can find out by running in a terminal xprop WM_CLASS and clicking anywhere in the V-REP window. Output on my machine: $ xprop WM_CLASS WM_CLASS(STRING) = " ", " ...

vrep.sh doesn't allow launching via absolute path or symlink

Since vrep.sh doesn't allow launching it via absolute path (e.g. /opt/vrep/vrep.sh) nor via a symlink to it (e.g. /usr/local/bin/vrep pointing to /opt/vrep/vrep.sh), I modified it. While editing it, I also added quotes where needed, so that in case the path to V-REP contains spaces, nothing breaks. ...

ROS and renaming TF frames

When using simExtROS_enablePublisher with topic='/tf' and specifying an auxString argument such as "child%parent" broadcasted frames are renamed. This is useful to match the configuration on the real robot, and especially useful when using multiple instances of the same robot (using tf_prefix), beca...

Re: [dumbQuestion] launching v-rep from launchr bar in Ubunt

The problem is that the unity launcher will not spawn a login shell, so it will not source your .bashrc (which is the shell initialization file where you usually load ros stuff, like sourcing /opt/ros/DISTRO/setup.bash). Since I need ROS, as a workaround for this, I created a launcher (put this in v...

Re: problem with depth sensor when running Linux in VM

Nope, also the Mesa SR4000 sensor gives me a black depth image (but RGB image is OK) when running in a virtual machine. Note: I think I erroneously assumed it was a 3.1.0->3.1.2 regression, because it worked on my lab pc with ubuntu 13.04 and vrep 3.1.0, but the same scene running on virtual machine...

Re: problem with depth sensor when running Linux in VM

Nope, I didn't solve it.

I tried all six combinations of {offscreen surface, invisible window, visible window} x {Qt, non Qt}, but none of them fixed the issue.

Re: problem with depth sensor when running Linux in VM

It seems a problem with the graphics driver when running ubuntu in a virtual machine (I updated topic title accordingly).

Re: 3.1.2 possible regression for SICK S300 sensor

It seems the RGB information of a vision sensor is there, but the depth information is not.
(note: I'm running in a virtual machine, Ubuntu 14.04)

As a double check can you suggest me a scene where the depth sensor is demoed so that I'm sure to be testing it properly?

problem with depth sensor when running Linux in VM

I'm using V-REP 3.1.2 linux 64-bit, and I'm unable to get correct readings from the provided SICK S300 sensor. It used to work in 3.1.0, but in 3.1.2, if you set script parameter showLaserSegments=true, you'll see that laser segments look like if they are "inside" the sensor mesh. Screenshot: http:/...
