[Testo disponibile solo in inglese] 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.

TouchDesigner is a media platform for visual programming of generative 3D and 2D graphics, video mapping, interactive installations and for creating applications.

Our course is designed to immerse the student in the maximum number of aspects of the platform in a short time. The course program includes sustainable working with 3D graphics, sound processing and synchronization with music programs and provides the key skills to create the user interface.

By combining theoretical and practical approach, this course gives in-depth understanding of software structure, data flow and 3D graphics.

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.
