I am new at using GtkGLExt/OpenGL and was wondering if anyone knows if you can render OpenGL on top of a static background image, such as a .png, jpg, etc. I have an application where I need to create a gui containing a image background (a drawing) that will, at times, have graphical objects moving over the top of it. I was hoping that I could use OpenGL to do the object rendering over the image background. Any help or suggestions would be greatly appreciated.
You will likely want to draw everything, including the background image, using OpenGL. The alternative would be to draw to a pixmap using OpenGL, then composite the results over the background yourself, but this would almost certainly be slower and more complex.
