# Shadertoy-Shaders # Image-Filtering
## About
Repository for every shader I've written for shadertoy This folder contains various filter that can be applied to 2D images. Every shader is written in GLSL and is supposed to deliver a simple
handson sample implementation. With some filters even implementing some optimization measures such as quicker blurs or magic numbers instead of constant functions.

# Chromatic-Aberration
![overview.png](https://git.teridax.de/teridax/Shadertoy-Shaders/raw/branch/main/Chromatic-Aberration/overview.png)
This is a crude implementation of a 2D filter mimicing the effect of chromatic aberration which happens with real world lenses
that are unable to focus light of different wavelengths to the same focal plane.
