All,
I'm seeing a problem that I'm hoping someone can shed some light on. I have an application that uses an OSG viewer (OSG version 2.8.2) embedded in a GLUT window. This application runs on both Windows XP and Linux (currently using RHEL 5.4). The machine is dual boot so the hardware is the same in both cases. The embedded OSG viewer is rendering a database which includes a VPB terrain using osgTerrain. When I run this application on Windows, everything (terrain, models, sky, etc.) renders fine. However, when I run the same application on Linux, using the same database, the terrain does not show up at all. I've verified that the terrain is being read in and added to the scenegraph as usual, but it is not being rendered for some strange reason on Linux when viewer->frame() is called. Everything else renders just fine in the rendering loop. Is there something special I need to do for Linux in the application to get the terrain to render? At this point, I'm at a loss as to what is causing this problem. For a sanity check, I've looked at the terrain database using osgViewer on the Linux box and everything renders fine. Is GLUT causing problems on Linux that aren't seen on Windows for rendering the terrain? Is there something else I can do to debug this problem on Linux? Any help or input would most appreciated. Thanks, -Shayne
