Star (#23)

Jonathan Frech, 1 May 2015

I had an idea to make a simulation which generates stars. Using my getCirclePos() function, two radii — an inner and an outer one — and a number of points I realized the idea in this program.

How it works

$\frac{360^\circ}{\text{number of points}}=\text{circle sector}$ $\frac{360^\circ}{\text{number of points}}=\text{circle sector}$
$\frac{360^\circ}{\text{number of points} \cdot 2}=\text{shifted circle sector}$ $\frac{360^\circ}{\text{number of points} \cdot 2}=\text{shifted circle sector}$
Using those to sectors — and alternating between the inner (shifted) and outer radius — the program connects the points and out comes a star shape.

How to use

“d” toggles debug mode (gray circles),
“f” toggles points being drawn (blue points at the corners).
