Mastering GLSL in TouchDesigner, Lesson 10: Basic Image Filtering
In this lesson of Mastering GLSL in TouchDesigner, we explore image filtering, a fundamental process for altering textures through pixel-based operations. You’ll learn how shaders efficiently apply color grading, convolution kernels, and post-processing effects, enabling a wide range of creative visual transformations. We’ll break down essential filters like blur, sharpen, edge detection, vignette, and chromatic […]
