Homeworld Effects Manual: setCircleSlices()
setCircleSlices(int num)
Useful values: Integers 3 or greater
Default value: 8
Circles will be created as num-gons.
The circles created by the createCircles() command are not actually circles. They are regular polygons. Remember those from geometry class? They approximate circles well and are much easier for a computer to process. By default they are octagons, but with setCircleSlices() you can change them to triangles, pentagons, or, umm, eighteenagons. Think of it as a pie. num is how many slices there are in the pie.
