Re: [ros-users] RViz/OGRE3D and PCL hardware requirements/re…

Ah, I see what you mean. Yeah, it seems reasonable performance wise for
the pcd viewer on the table_scene_lms400_downsampled.pcd.
table_scene_lms400.pcd (not downsampled) feels slightly jittery, but
it's completely responsive to my panning around. I couldn't test it on
my own pcds from the PR2 because I haven't installed an updated version
of pcl on my home computer, but I'll try updating pcl and see whether
that makes any difference.
