Intermediate : Volumetric Lights in TouchDesigner
About this Course
Touchdesigner is a powerful tool to create interactive media performances and installations. However, some popular rendering techniques like volumetric lights have been impossible to achieve out of the box.
And that hasn’t changed. However Lucas Morgan, creator of the Touchdesigner-based Lighting Software GeoPix has spend countless hours to develop a pretty straightforward method to create beautiful volume lights with custom GLSL code – and he is ready to share with you.
In this course you will learn how to create a custom lighting system on top of TouchDesigner spotlights and use atmospheric volumetric lights in you renders.
