This is my first post on this forum so I will start with a hello.
Phew, now that I’m done with that here is my problem.
I am a beginner with GLSL so I’m still a little unsure about how to get certain bits of information. I need to find out the boundaries for the edges of the screen, so if a window is 800x600 I need to get that x and y value. So far I am using
float x = gl_FragCoord.x;
float y = gl_FragCoord.y;
to check the current fragments position.
Is there a way to get the max of gl_FragCoord or another way to find those values.
Also I want to mention that I need to get these values inside the shader, so I can’t just pass the resolution via a uniform value.
The effect I am going for is faded edges on the screen.
