Hello!
I want to create an opengl Window without any background (fully transparent). I only want to see the 3D-Shapes, drawn over whatever application or desktop is visible behind.
With this I want to make a unique “Splah-Screen” for my application.
Is there a way to do this in pure OpenGL, without use of shaders?
I was thinking of something like clearing the screen with a transparent color, or maybe overlay windows.
But nothing I tried so far gave me the appropriate result. I would be glad if somebody could tell me if this is possible at all, and what keywords I should google for.
Of course, if somebody has a code example it would be great!
Regards, Juergen
