$ stack runghc src/Introduction/PerlinNoiseGraph/Sketch.hs
Chapter I.6 starts with a graph of 1D Perlin noise. Perlin noise is based on a set of values:
- Octaves
- Scale
- Persistance
In this sketch you can dynamically modify these values and see the effect on the graph.
It is not an example or exercise in the book, I just created it so I could get a better understanding of Perlin noise.
