In the last line of the input window there is the command
fracPolygone(5,100,0.4,5);
The meaning of the parameters is
- 5: number of vertices of the regular polygone,
- 100: length of a side of the initial poylgone,
- 0.4: shrink factor from one level to the next,
- 5: number of recursion steps
- 1
