Rviz render panel on GPU
I am currently writing a QT GUI that uses rviz render panels. I have determined that these render panel instances are not automatically running on my GPU, since they slow down as my processor gets bogged down. A standalone Rviz instance does not have the same sluggishness under these conditions, therefore I assume it is running on the GPU. What do I need to do in order to have a librviz render panel instance run on the GPU?
I´d be very surprised if the renderpanels don´t make use of the GPU, but we´ve been facing similar slow-down issues (in a probably very similar application ;) ), so I´d be also very interested in the underlying reasons/potential fixes.
I still have not found a solution to this. Anyone have any ideas?
