Simple gaussian blur shader using a kernel
This tutorial demonstrates creating a gaussian blur shader using a kernel and the GLSL shader language. The process involves creating a kernel, defining a sample distance, applying blur, and setting the pixel alpha. Images with different sample distances are displayed for comparison. Thank you for reading this helpful guide!
