Spyral

Draw some cool spirals!

The goal

With Spyral you can draw cool and mesmerizing spirals!

Note: this is a work in progress, done quickly. There is plenty of room for improvement. So feel free to make some changes and improve this project :)

How it works

1. Make convex polygons:

   1. Generate N random points (seeds)
   2. Get the Voronoi diagram from the seeds (see scipy)
   3. Get a set of vertices and regions (linked vertices) from the Voronoi diagram

2. Draw spirals inside each polygon (region) generated:

   Do the follwing until a stop condition is true:

   1. Draw a line from one polygon's vertex to another.
   2. Move the vertex along the edge so that it is closer to the next vertex.
   3. Move to next vertex.

Example

Generate a 1500*500 banner:

raw_image(width=1500, height=500)

output :

Generate a 1500*500 black and white banner:

raw_image(width=1500, height=500, color=(0, 0, 0)

output :
