Shadertoy is a web tool that allows developers all over the globe to push pixels from code to screen using WebGL. Developers can create shaders in a live-coding environment that allows them to see the final results as they are coding. The creations can react to various inputs, such us music, videos, time of day, or even a webcam.
In addition to the coding tool, Shadertoy.com introduced a social platform, for sharing feedback and promoting great work. The site opened on 18 February 2013, and within the first week received more than 150 pieces showing a great variety of rendering techniques, from post-processing effects, procedural raymarchers, and raytracers to demoscene pieces.
It is a place for professionals and students alike to learn and teach about visuals, interactions, reactivity, procedural modeling, GPU internals, and shading.
Visual performances such as those seen in exhibitions, museums, and events should take advantage of advanced rendering technology to create the most immersive experience possible. This project achieves immersion by merging three principles: reactivity, visual quality, and interactivity.
Reactivity adds dynamism and links visuals with the music, as opposed to the classic approach of pre-recorded content. Most of the event can be left to improvisation (through different input devices like MIDI controllers), letting the performance flow seamlessly with the music.
Visual quality (landscapes, colors, textures, and shapes) is mostly created procedurally in real time. There are no pictures or recorded footage, so every aspect of the imagery can be changed as needed during the show.
Finally, the audience can interact with the show, making them feel part of it. The interactivity is achieved with mobile devices, 3D cameras, and standard cameras.
Each show is unique, the artist can even write code in real time during the event.
So, how do I play Yo ?
