Algorithmic Doodle Art: Brambles with buds

Landscapes in films are often computer generated. Ever wondered how they do it? Next time you find yourself doodling, draw an algorithmic doodle and explore algorithms for drawing real and fantasy nature.

Here is an example Doodle Algorithm of brambles with buds.

1. Start by drawing a wavy green line with small lines sticking out at angles from it on either side (as below)

2. DoodleDraw from that line as follows.

To DoodleDraw from a given line:


a. Draw a new wavy line from the chosen line with small lines sticking out at angles from it on either side.


b. Draw a red bud shape from the end of the line

2. Choose a new existing line and DoodleDraw from that line


As you choose the exact positions and lengths of lines randomly you will get a slightly different picture just as no two plants are identical. Different algorithms give different looking trees, grasses, ferns, snowflakes, crystals.
