Video is an integral aspect of intermedia performance, pairing with music, theatre, and dance. Following a core overview of non-linear editing, including colour correction and grading, this course will focus on interactive system development with TouchDesigner, exploring image manipulation, external and programmatic control, compositing, audio and motion reactivity, and effect processing. This course will also cover 3D graphics, including geometry, material, light and shadow, instancing, and animation, and introduce the OpenGL Shading Language and Python. Coursework is practical, with a focus on creating intermedia, culminating in a final project.
