The fractal we will now draw is formed of a big triangle inside which several smaller triangles are embeeded. The prototype of the fuction to draw it is the following:
[!java]void [/!]sierpinski([!java]int [/!]level[!scala]:Int[/!], [!java]double [/!]length[!scala]:Double[/!])
Have a look at each world's objective view to understand how to write the function.
