TouchDesigner Vertex Shader 01: Instancing and Deformation
Unlock the full power of the GPU using vertex shaders in TouchDesigner! This tutorial is meant to be an introduction to vertex shaders, using a simple use case to demonstrate their applicability and ease of use. We will create a pulsating, rippling field of instanced lines, all deformed on the GPU using the vertex shader for super fast, high quality renders. Check out this video for a great lesson on the rendering pipeline and how vertex shaders fit into the bigger picture: https://www.youtube.com/watch?app=desktop&v=F7bpcyPhiH8 Project files on patreon: www.patreon.com/water__shed 00:00 - Intro 01:22 - Network Overview 03:00 - What is a Vertex Shader? 06:39 - TouchDesigner Vertex Shader Documentation GLSL Material 12:23 - Setting up Parameters and Uniforms 15:18 - Vertex Shader and Instancing in TouchDesigner 29:01 - Using sampler2D uniforms in vertex shader 34:58 - Wireframe and Line Width 39:09 - Blending and Depth Testing 41:23 - Camera Blend and Lighting
