Python script for calculating and drawing triangular meshes. The mesh is the Delaunay triangulation of a random assortment of points. For more details on how this works, see https://www.peterbeard.co/blog/post/delaunay-triangulation-makes-pretty-pictures/
- Uses the Python Imagimg Library (PIL) to read/write image files
Usage: delaunay.py [options]
Options:
-h, --help show this help message and exit
-o FILENAME, --output=FILENAME
The filename to write the image to. Supported
filetypes are BMP, TGA, PNG, and JPEG
-n N_POINTS, --npoints=N_POINTS
The number of points to use when generating the
triangulation.
-x WIDTH, --width=WIDTH
The width of the image.
-y HEIGHT, --height=HEIGHT
The height of the image.
-g GRADIENT, --gradient=GRADIENT
The name of the gradient to use.
-i IMAGE, --image-file=IMAGE
An image file to use when calculating triangle colors.
Image dimensions will override dimensions set by -x
and -y.
-k DARKEN_AMOUNT, --darken=DARKEN_AMOUNT
Darken random triangles my the given amount to make
the pattern stand out more
-a, --antialias If enabled, draw the image at 4x resolution and
downsample to reduce aliasing.
-l, --lines If enabled, draw lines along the triangle edges.
-d, --decluster If enabled, try to avoid generating clusters of points
in the triangulation. This will significantly slow
down point generation.
-r, --right If enabled, generate right triangles rather than
random ones.
-e, --equilateral If enabled, generate equilateral triangles rather than
random ones.
