WebSep 5, 2024 · Instead of calculating the mean of all values, we now multiply each sample with this Gaussian weight instead. Looking at the result, it's clear that the Gaussian blur gives much fewer artifacts and looks more like an optical blur. It is worth noting that calculating the Gaussian weights in the fragment shader can be quite expensive. WebImage shaders: fragColor is used as output channel. It is not, for now, mandatory but recommended to leave the alpha channel to 1.0. Sound shaders: the mainSound() …

WebThe blur shader uses a normal (or Gaussian) distribution. For the 2 passes is used the same shader program, with individual direction settings for the 2 passes, stored in the uniform vec2 u_dir.
