Description Pixelization is one of the simplest effects to implement. The main idea behind this effect is to divide the screen into squares of arbitrary size and then for each of these squares, sample a single color from the source image. Taking this one step further, it’s possible to use different shapes to subdivide the screen space (eg. circles), achieving a more complex visual feel. Samples Below you can see examples of the effect implemented in shadertoy. Simple pixelization #define LU...
