Shaders in Processing 2.0 – Part 2   9 comments

The new capability of loading user-provided GLSL shaders into Processing’s P2D and P3D renderers opens up the possibility of customizing all the rendering operations in Processing, as well as of creating interactive graphics that would be very hard or impossible to generate otherwise. For OpenGL web applications, WebGL supports (only) programmable pipelines through GLSL shaders, and this has motivated the creation of online repositories of shader effects that can be run directly from inside the web browsers, as long as they support WebGL. Sites like the GLSL sandbox or Shader Toy hold large collections of shader effects that can be edited and controlled interactively through the browser. This new post will explain how to integrate GLSL shaders from the GLSL sandbox and Shader Toy websites into a Processing sketch.
Update: With the release of Processing 2.0 final, some of the contents in this post are outdated, please check this tutorial for a detailed description of the finalized shader API.
