Procedural image generator
This tiny project is a procedural image generator that starts with a random top row of pixels, and iteratively generates the rows below according to some rule. Each row depends only on the row immediately above.
- Primitive 1-to-1. Pixel's RGB values are jittered RGB values of the pixel above.
- Genetic, 2 parents. Each pixel has 2 parents: dad (above left) and mom (above right). R, G, and B values are genes. Alleles are chosen randomly and independently from mom or dad and jittered (think inheritance with mutation).
- Genetic, 3 parents. Each pixel has the pixel immediately above as third parent in addition to 'mom' and 'dad' from 2.
- Averaging, 2 parents. RGB values of pixel are averaged mom and dad's RGB values with some random noise added.
- Averaging, asymmetric, 2 parents. Same as 2, except dad is directly above, mom is above right.

This produces the
row_by_row executable, which takes 4 mandatory parameters:
width in pixels,
height in pixels,
strategy (1-5, per numbering above),
filename where the image is saved. The output is in PPM format.
