Online coding community site to demonstrate examples of 3D graphics programming, offering smooth and interactive WebGL rendering in your browser:
Shadertoy is the first application to allow developers all over the globe to push pixels from code to screen using WebGL since 2009.
This website is the natural evolution of that original idea. On one hand, it has been rebuilt in order to provide the computer graphics developers and hobbyists with a great platform to prototype, experiment, teach, learn, inspire and share their creations with the community. On the other, the expressiveness of the shaders has arisen by allowing different types of inputs such as video or sound.
