[ros-users] openni_camera not publishing any data

[Tom Birch]

High five! I'll write up a ticket and then start trying to debug it.

You don't, by chance, see a bug in rviz where the z-buffer is ignored
do you? i.e. objects occlude in the order they are drawn, not in order
of distance from the camera. This could just be a driver issue, but I
need to find some other obvious example of z-buffers to test it.

Just out of interest, why do you run ROS inside linux instead of on
OSX? Would you run it on OSX if you could install it with just a .pkg?

cheers,
Tom

I'm running Ubuntu 10.10 in VMware on top of OSX, but I've verified that the kinect works in this setup by running the freenect demos. Is it possible the freenect driver is somehow conflicting with the openni driver?
