In this shader tutorial, we will go over two common image processing techniques: box blur and Gaussian blur. We start by understanding the algorithm for box blur. Then we learn how to create a Gaussian blur by adjusting the weights in the kernel. Finally, we learn how to code both the box blur effect and the Gaussian blur effect, in a GLSL shader. 📖 Code - https://github.com/SuboptimalEng/shader-tutorials 🐦 Twitter - https://twitter.com/SuboptimalEng 💻 GitHub - https://github.com/SuboptimalEng 🌎 Website - https://suboptimaleng.com/ == [ Resources ] == Inigo Quilez’s Articles - https://iquilezles.org/articles The Book of Shaders - https://thebookofshaders.com/ VS Code GLSL Shader Setup Guide - https://www.youtube.com/watch?v=7UvpTTEE1Hs == [ Timestamps ] == 00:00 Intro to Blur Effects 00:23 Gaussian Blur Algorithm 02:29 Box Blur Shader 05:26 Gaussian Blur Shader == [ Tags ] == #suboptimal #glsl #shaders
