Detailed Description

Regular n-sided polygon computations.

Function Documentation

function ngon_vp	(	n	,
		r	,
		vr
	)

Compute the vertices for an n-sided equiangular/equilateral regular polygon.

Parameters

n	<decimal> The number of sides.
r	<decimal> The ngon vertex radius.
vr	<decimal> The vertex rounding radius.

Returns

<vector> A vector [v1, v2, ..., vn] of vectors [x, y] of coordinates.

Example

vr=5;

hull()
{
  for ( p = ngon_vp( r=20, n=5, vr=vr ) )
    translate( p )
    circle( r=vr );
}
