Hi Shayne, There isn't nothing platform specific about osgTerrain, and I do all my dev and testing of osgTerrain under Linux. There shouldn't be any correlation between GLUT and osgTerrain either. I'm afraid I no explanation for your findings.
What I can say is that GLUT is a truely awful API and shouldn't be used anywhere any modern graphics application. It was written for tiny OpenGL demos, and long exceeded it's intended life a decade ago, let alone now, it's survived not because it's actually any good, but because well... lots of people copied those early demos. osgViewer itself is a far better tool for a modern graphics application. Might I suggest you use it rather than GLUT. Robert.
