1dca

manhattan rain and variants
Programs creating generative art based on one-dimensional cellular automata (chiefly rule 184)

binaries

• 1dca seeds a horizontal line and evolves generations upwards and downwards based on a custom rule - outputs pbm data to stdout
• 1dca2 similarly evolves multiple layers of rule 184 in a "noisy environment" - writes a pgm file
• 1dca3 same as 1dca2, but in color - writes a ppm file
• 1dca4 same as 1dca3, but generating multiple files, gradually moving the layers before combining them, the colormap is also different - writes multiple png files by piping to pnmtopng
• 1dca5 similar to 1dca4, but instead of generating files everything is rendered on the screen with sdl and opengl

examples

• 1dca rule 110:
  
• 1dca2:
  
• 1dca3:
  
• combination of 1dca4 output frames (lots of detail lost in video compression though):
