Render GLSL fragment shaders to images, then draw them in a sketch. Use clipping and blend modes to combine them with shapes. You can also pass rendered sketches or shader images into another shader.
See the source code for this page for the full examples.
These examples draw a shader image, clip it to a polygon, and blend noise with a background and star.
