It is possible to implement fragment shader to do one-pass gaussian blur? I have found lot of implementation of two-pass blur (gaussian and box blur):

and so on.

I have been thinking of implementing gaussian blur as convolution (in fact, it is the convolution, the examples above are just aproximations):

Hi All, I am trying to get update the eye position in my shader from my appliaction but I keep getting error 1281 when I attempt this.

GLSL check if fragment is on geometry

I am currently writing the positions of my geometry to the RGB channels of gl_FragColor and I would like to write 1.0 to the alpha channel if the fragment is part of geometry, and 0.0 if its empty. Is there a simple way to tell if a fragment is geometry or not? Maybe through gl_FragCoord.z? thanks >>> More

(note this question is closely related to this one however I didn't fully understand the accepted answer) To support videocards in laptops I have to rewrite my GLSL 330 shaders to GLSL 130. I'm trying to do this but somehow I don't get vertex attributes to work properly. My 330 shaders look like… >>> More
