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:    • 4: Vertex & Fragment Shaders In Swift...
