Ultraviolet

Ultraviolet is a Scala 3 to GLSL (versions 100 and 300) transpiler library built on top of Scala 3 inline macros.

Examples can be found in the examples directory of this repo. You can use Ultraviolet to generate GLSL shader code for Indigo, and also for ShaderToy.

TL;DR: What is a Shader / Ultraviolet / basic programmer intuition

If you've stumbled across this repo and have no idea what all this shader stuff is about:

1. A shader program is used to render graphics on a GPU.
2. Think of a tiny C-like program that runs for every pixel on the screen.
3. Ultraviolet allows you to write those programs in Scala 3.
