An Intro to Generative Art with Scala
summary
Scala code uses Processing jars (manual extraction then a provided template) and scala-cli to live‑code flow fields: a 1000×1000 canvas, grid resolution (width 0.01), Perlin noise for smooth angles, and step parameters that change output dramatically. Examples plot up to hundreds of 500 lines with configurable step length* and stop when off‑grid; a NoLoop fix prevents continuous reseeding. Repo “intro to flow fields and Scala” contains runnable examples.
