In this session, the Shadertoy.com creators will change the way you think about fragment shaders. During the last three years, the Shadertoy community has been trying to answer one question: What can a fragment shader do? The results have been mind-blowing. People from all over the world collaborated to break the limits of what was possible: procedural content, incredible raymarching tricks, VR or even GPU generated music. This year there is a new challenge: What can multiple fragment shaders do? Imagine fragment shaders could talk to each other and finally build complex algorithms running on the browser using your GPU. Join the Shadertoy creators to discover new ideas and techniques to create fragment shaders that are games, progressive path tracers, sorting algorithms, demos and more.
