OpenGl blurring

QUESTION

OpenGl blurring

Asked 2020-Nov-16 at 09:30

I'm using libgdx and want to make a common Gaussian blur post-processing effect. Following this guide I faced some issues with texture filtering. Here the images:

actual image:

blurred with radius = 1:

blurred with radius = 5:

In the simplest case, I just have a transparent frame buffer object with some objects rendered to it. Then I need to apply some shader effects to this, basically only blur and then render the result to the screen. I also want to adjust the blur radius, but if I set the radius to more than 1 it becomes looking very rough. Guess it should be used with some linear filtering, but it isn't here. So I just need the same effect applied with a soft blur and configurable radius, maybe some other shader-sided options. And I've also tried to explicitly assign Linear filtering to FBO textures, which doesn't change anything.

Fragment shader:

From what I see you are not doing Gaussian blur at all...

Gaussian blur on image is convolution between image and Gaussian weighted matrix of resolution 1+2*r where r is radius of your blur. So outputted color should be weighted sum of all pixels up to distance of r from the targeted pixel.

What you are doing is just weighted sum of 9 pixels regardless of the radius that is wrong (in my optinion) as you should sum up ~6.28*r*r pixels instead. So I would expect 2 nested for loops instead ...

Here a small GLSL example I just busted together:
