Re: [osg-users] Composite Viewer framerate multiple cameras on large data

HI Nick, What type of frame rate do you get when running on a single window vs multiple windows? What do the frame stats suggest for what is the bottleneck? Sharing context won't help as it'll force you to use single threaded viewer. There might be other routes though, so as just using one

[osg-users] Composite Viewer framerate multiple cameras on large data

Hi, I have a scene graph set up with a large dataset ( A Geocentric Earth from osgEarth). In my composite viewer, I want to have multiple viewpoints (with separate camera manipulators/projection matrices; ie. an Orthographic, perspective, etc) each within a QT widget. I got this set up the
