2D GLSL - Procedural Graphics & Postprocessing

Link to this page location: #about

Course target

This short and practical course can be a good introduction in the world of GLSL programming.

You will learn various topics related to 2D GLSL, including:
Generative 2D patterns & Noises
Distant fields based on 3D point positions
Color correction and Postprocessing effects
Porting Shadertoy Shaders

Time proven approach ...

We believe that our course's approach to teaching TouchDesigner is unique and effective in that we provide our students with a hands-on learning experience that allows them to experiment and create freely..

Our course material is structured in a way that is easy to understand.

TouchDesigner 301

GLSL or OpenGL Shading Language (GLSL), is a high-level shading language with a syntax based on the C programming language. Besides its use for creating 3D objects, it can be also used for generating textures and post-processing of video stream data.

In this course, we gather a lot of practical examples of creating generative graphics and effects. The course is adapted to TouchDesigner environment, but all the techniques and tips, included in the course program, can be used in other environments with minor changes.

Who is the course for?

The course is designed for students of different levels, as well as for the media artists, VJ’s and musicians, who want to expand their visual performance show.

Stanislav Glazov

Instructor for TouchDesigner integration




For more than 20 years, he has worked in light and visual art, seeking innovative opportunities where art and technology intersect. His installations and AV performances explore themes such as inner and social freedom, consciousness, identity, and loneliness in the modern world, using high-tech techniques.

Driven by his desire to create unforgettable experiences that inspire, he takes an individualized approach to each work, creating unique algorithms and synchronizing sound with visuals and digital shapes. He is also known for producing music with modular synthesizers and analog devices, influenced by industrial music, which combines noise, disharmony, and shamanism to take listeners on an intense emotional journey.

In 2013, he created his own generative design studio Licht.Pfad.

Creation of AV Performances in partnership with Dasha Rush, Robert Lippok

Performances at all the iconic festivals of the planet: Berlin Atonal, Mutek Montreal, Ars Electronica Linz, Unsound Festival in Krakow, Raster-Noton night in Berghain, Barbican London, Resonance Festival in Tokyo, Mira Festival Barcelona, L.E.V. Festival, Light Festival Lyon

Since 2016 - working on theater projects with Maxim Didenko, including the creation of media servers for various performances

Minimum skills (not strongly required, but get ready to learn): familiarity with command line (shell) operations.
Programming skills will greatly help with exploring specific details of the used instruments.

Complete course program would require Windows computer with a decent Nvidia GPU with at least 6Gb VRAM (hard minimum is 1060, reasonable level 2070+).
Users with Macs would be able to use Collab versions (no integration with TD in this case).

Partial payment option available: 50% before the start of the course and 50% 1 month after the start

All practical topics have corresponding tasks to complete as homeworks. Most of them require to repeat the actions from the lectures on your own supply.We recommend to execute them even if everything is clear in theory - to ensure that you won’t face unexpected issues in your future work.
During final week you will have to develop and complete your own project (with our assistance) as a kind of exam of the obtained knowledge.

10-12 hours per week should be sufficient to master necessary concepts and skills. You may want to invest more time for more exhaustve explorations though. Remember, the course program is somewhat open-ended: nearly all topics are not limited in scope, and have lots of options for extra developments.
