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 snowflake.
1. Start by drawing six straight lines from a single central point (as below)
2. DoodleDraw from each line as follows.
To DoodleDraw from a given line:
1. Draw 3 shorter lines at different angles on the left of the line.
2. Draw 3 symmetrical lines from the same points on the right of the line.
3. 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.
