Level: Advanced

These workshops will introduce you to the ImmersAV toolkit. The toolkit brings together Csound and OpenGL shaders to provide a native C++ environment where you can create abstract audiovisual art. You will learn how to generate material and map parameters using ImmersAV’s Studio() class. You will also learn how to render your work on a SteamVR compatible headset using OpenVR. Your fully immersive creations will then become interactive using integrated machine learning through the rapidLib library.

Session Learning Outcomes

By the end of this session a successful student will be able to:

• Setup and use the ImmersAV toolkit

• Discuss techniques for rendering material on VR headsets

• Implement the Csound API within a C++ application

• Create mixed raymarched and raster based graphics

• Create an interactive visual scene using a single fragment shader

• Generate the mandelbulb fractal

• Generate procedural audio using Csound

• Map controller position and rotation to audiovisual parameters using machine learning

Session Study Topics

• Native C++ development for VR

• VR rendering techniques

• Csound API integration

• Real-time graphics rendering techniques

• GLSL shaders

• 3D fractals

• Audio synthesis

• Machine learning

Requirements

• A computer and internet connection

• A web cam and mic

• A Zoom account

• Cloned copy of the ImmersAV toolkit plus dependencies

• VR headset capable of connecting to SteamVR

About the workshop leader 

Bryan Dunphy is an audiovisual composer, musician and researcher interested in generative approaches to creating audiovisual art in performance and immersive contexts. His work explores the interaction of abstract visual shapes, textures and synthesised sounds. He is interested in exploring strategies for creating, mapping and controlling audiovisual material in real time. He has recently completed his PhD in Arts and Computational Technology at Goldsmiths, University of London.

Level: Intermediate

In this workshop you will use openFrameworks to build a real-time audiovisual instrument. You will generate dynamic abstract visuals within openFrameworks and procedural audio using the ofxMaxim addon. You will then learn how to control the audiovisual material by mapping controller input to audio and visual parameters using the ofxRapid Lib add on.

Session Learning Outcomes

By the end of this session a successful student will be able to:

• Create generative visual art in openFrameworks

• Create procedural audio in openFrameworks using ofxMaxim

• Discuss interactive machine learning techniques

• Use a neural network to control audiovisual parameters simultaneously in real-time

Session Study Topics

• 3D primitives and perlin noise

• FM synthesis

• Regression analysis using multilayer perceptron neural networks

• Real-time controller integration

Requirements

• A computer and internet connection

• A web cam and mic

• A Zoom account

• Installed version of openFrameworks

• Downloaded addons ofxMaxim, ofxRapidLib

• Access to MIDI/OSC controller (optional – mouse/trackpad will also suffice)
