CPLremovecollinearpoints
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - CPL/Closed Polygon Lists
Introduced first in SolidGeometry 5.6, Creation date: 2025-09-14, Last change: 2025-09-15
removes 2D/3D collinear point with different results for opened and closed CPL/CVL
Use carefully: The 'CPLremovecollinearpoints' function has not yet been extensively tested
Description
For closed and opend CPL/CVL in 2D/3D. Start and end points can be removed for closed CPL/CVL if there is no kink when it is a closed contour.If it is an open contour, be aware that start an endpoint will remain, even they are collinear points

Input Parameter
CPL: | | 2D/3D open or closed CPL; Behavior differers |
Examples
CPLremovecollinearpoints(circshift(CPLaddauxpoints(PLsquare(10),1), 0)) % open CPL remain Start/End
CPLremovecollinearpoints(circshift(CPLaddauxpoints(PLsquare(10),1),-1)) % open CPL remain Start/End
CPLremovecollinearpoints(circshift(CPLaddauxpoints(PLsquare(10),1),+1)) % open CPL remain Start/End
CPLremovecollinearpoints(closedCPL((circshift(CPLaddauxpoints(PLsquare(10),1), 0)))) % closed CPL
CPLremovecollinearpoints(closedCPL((circshift(CPLaddauxpoints(PLsquare(10),1), 0)))) % closed CPL
CPLremovecollinearpoints(closedCPL((circshift(CPLaddauxpoints(PLsquare(10),1), 0)))) % closed CPL
