So, I’m working on a molecular modeling tool that works pretty well. My problem- I want to be able to run it in a mode where it’s only output is a bitmap, with no graphics displayed. I can print out my bit map, but it always flashes a window to the screen. Can this be done? Can it be done on a machine not running X? (It has to run in linux on a machine that is not concurrently running X) I’m using GLUT to handle the windowing tasks.
Further Observations: It seems that I have to enter glutMainLoop to get any drawing commands to be written to the viewport, displayed or not And glutMainLoop automatically opens the window.
