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 nature.
Here is an example Doodle Algorithm of a kind of grass.
1. Start by drawing a single slightly curved vertical line (as below)
2. DoodleDraw from that line as follows.
To DoodleDraw from a given line:
1. Draw 3 shorter curving lines from the top two thirds of the line on its lower side.
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.
