CPLconvexhulloutline
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - CPL/Closed Polygon Lists
Introduced first in SolidGeometry 5.1, Creation date: 2021-02-28, Last change: 2025-09-15
creates a ONE region CPL from several regions of a CPL by using the convex hull
Description
By using the parameter t, a lot of different possibilities exist:
CPLconvexhulloutline(CPLsample(14),1,0,'default'); % convexhull
CPLconvexhulloutline(CPLsample(14),1,0,'delaunay');% convexhulldelaunay
CPLconvexhulloutline(CPLsample(14),1,0,'fillgap'); % convexhullfillgap

Example Illustration
Syntax
CPLN=CPLconvexhulloutline(CPL,[b,r,t])
Input Parameter
CPL: | | Original CPL with more than one region |
b: | | buffer distance; default is 0 |
r: | | radius of edges; default is 0 |
t: | | type of convex hull: 'default', 'delaunay', 'fillgap' |
Output Parameter
Examples
CPLconvexhulloutline(CPLsample(26))
CPLconvexhulloutline(CPLsample(12))
CPLconvexhulloutline(CPLsample(14),1,2) % Buffer distance of 1, Radial edges of 2
CPLconvexhulloutline(CPLsample(14),1,0,'delaunay'); % Shape is delaunay
CPLconvexhulloutline(CPLsample(12),1,0,'fillgap'); % Shape is fillgap
