GLSL shaders have revolutionized computer graphics, unlocking the raw power of the GPU and transforming complex mathematical formulas into breathtaking visuals. In a dynamic environment like TouchDesigner, shaders act as a creative superpower, enabling real-time generative art, data visualization, and interactive experiences.

Despite the wealth of tutorials available online, many assume prior knowledge of GLSL, making it difficult for beginners to grasp the fundamentals. This workshop, led by VanTa, takes a step-by-step approach, guiding you through the essential concepts needed to write your own shaders from scratch.

Designed for programmers, designers, and curious minds, this course breaks down the complexities of GLSL in an accessible and engaging way. Whether you want to deepen your understanding of computer graphics or simply explore how pixels are drawn on a screen, this course will give you the tools and knowledge to bring your creative ideas to life. Some prior experience with computer graphics is helpful but not required.
