Introduced first in SolidGeometry 1.0, Creation date: 2012-10-19, Last change: 2025-09-14

returns a 2D point list of a circle or circle segment

Description

PL circle starts not(!) at (R,0), but the first edge is going in y-direction. This has been done to simply generate squares or 2*n-Polygons. By using the offset angle, it is possible

Syntax

PL=PLcircle(R,[nf,dw,Ry,ow])

Input Parameter

R: Radius or list of radii of concentric circles (Rev. 5.0)
nf: number of facets (default is nofrd (R,0.05))
dw: circle segment ](0..2(pi] (default is 2*pi)
Ry: Radius if ellipse (default is R)
ow: Offset angle

Output Parameter

PL: Point / Vertex list

Examples


PLcircle(5) % radius is 5
PLcircle([3 5]) % Radius is [3 and 5]
SGfigure; CPSplot(PLcircle([10 20 30 40]))
