Mastering GLSL in TouchDesigner, Lesson 11: Convolution Kernels

In this lesson of Mastering GLSL in TouchDesigner, we explore convolution kernels, a powerful technique for image filtering that allows for effects like sharpening, edge detection, embossing, and Gaussian blur. You'll learn how convolution matrices modify pixel neighborhoods and how to implement multi-pass filtering for dynamic effects. 📌 Key Topics Covered: ✅ Understanding convolution kernels and how they alter images ✅ Implementing sharpening, edge detection, and motion blur ✅ Using mipmaps and textureLod() for efficient sampling ✅ Applying multiple shader passes for more complex effects 🎨 Exercises & Challenges: 🛠️ Implement a custom convolution kernel from scratch 🛠️ Build a CRT effect with vignette, scanlines, and chromatic aberration 🛠️ Create a unique effect by combining multiple filtering techniques Explanation of kernels with some good illustrations:   / image-convolution-filtering   Interactive convolution kernel explorer: https://setosa.io/ev/image-kernels/ Find me online: 🔹 Project Files & Patreon:   / water__shed   🔹 Portfolio: https://www.lakeheckaman.com 🔹 Instagram:   / lake_heckaman   00:00 - Start 00:04 - Intro: Advanced Image Filters with GLSL 01:08 - Image Convolution Kernel 09:49 - Implementing kernels in GLSL 12:11 - Mipmaps 16:39 - Convolve TOP 17:56 - Begin TouchDesigner Examples 19:08 - TextureLOD 22:36 - Edge Detection (Sobel Filter) in GLSL 27:33 - Sharpen Filter 31:30 - Emboss 32:34 - Barrel Blur GLSL TouchDesigner 34:24 - Exercises
