Create Music Visuals with TouchDesigner / Going Further - On-demand

Make visuals with particle systems and PBR materials in TouchDesigner.

Course Instructor: Masha Rozhnova

Course level

TouchDesigner is a tool that gains popularity among musicians who want to create visuals for their music and do audio-visual experiments. The goal of this course is to show how one can start with TouchDesigner and not risk being discouraged. You will learn the basic concepts underpinning creation and rendering of 3D geometries, what different parameters of PBR materials mean and how particle systems work. The concepts you learn will be used to create shiny and noisy audio-reactive visualizations that can be plugged into your live performance straight away.

What you'll learn

  • Session 1: SOP generators and filters, Operators that use CPU and GPU, Geometry Instancing and Connecting Trigger CHOP to different frequencies of an audio-spectrum
  • Session 2: FBX and OBJ formats, Polyreduce and Subdivide SOPs, Delete SOP, Transform SOP, The theory of Physically-Based Rendering and Shading, PBR maps and PBR setup in Touch Designer
  • Session 3: Particle SOP inputs (emitter, attractor, force), Particle SOP parameters, Differences between CPU and GPU particle systems and Navigating TouchDesigner Resources

Requirements

  • A computer and internet connection
  • A webcam and mic
  • A Zoom account
  • A three button mouse or Apple Track Pad appropriately configured
  • TouchDesigner installed
  • If your on Mac please check TouchDesigner can run on your system (i.e. has basic GPU requirements such as Intel HD4000 or better)
