When I use an FBO I can define its image type (ex.: OF_PIXELS_RGBA). Can this be done for the main window?
I’m creating a drawing adding thousands of transparent layers of a very transparent black (0,0,0,1). Theoretically, after 256 layers applied to a pixel its color should be opaque black (0,0,0,256). But it tends to grey and stays there.
This has been discussed here:
And @arturo suggested looking at example
gl/fboTrailsExample which I did. This example describes something very similar to what I’m experiencing.
But all this applies to FBOs.
I was wondering if total black can this be achieved without FBOs, only by drawing directly to the screen. Can it?
