# Perlin Builder

Generates 2d terrain and heightmap jpeg using Perlin noise.

Probably a good place to look in for anyone starting with Nannou.

I wrote this project to learn about Nannou and Rust. Constructive criticism is more than welcome.

## Controls

- 'O' && ( '+' || '-' ) : Adjust the octaves.

- 'Z' && ( '+' || '-' ) : Zoom in and out

- 'W' && ( '+' || '-' )  - 'H' && ( '+' || '-' ) : Adjust the image dimensions.

- 'S' Save the image to the current directory.

- 'R' Get a new random seed.

- 'M' Toggle between the two modes, colored terrain or heightmap.

## Some examples

#### A typical view when the program starts:

#### The same view with 4 octaves:

#### And with 1 octave:
