Vojtech Bubnik	11c0e567a6	WIP "ensure verticall wall thickness" rework: ... 1) New region expansion code to propagate wave from a boundary of a region inside of it. 2) get_extents() extended with a template attribute to work with zero area data sets. 3) ClipperZUtils.hpp for handling Clipper operation with Z coordinate (for source contour identification)	2022-12-20 09:09:10 +01:00
Vojtech Bubnik	db3f696888	Fixed ExPolygon::overlaps(), which was not commutative. ... Wrote unit tests for Clipper polyline clipping operations. Rewrote ExPolygon unit tests from Perl to C++.	2022-11-15 15:32:16 +01:00
Lukáš Hejl	46ade54937	Backported a fix from Clipper 6.4.2 for the issue that Clipper Z coordinated has incorrect value because ZFillFunction wasn't called in all cases (https://sourceforge.net/p/polyclipping/bugs/160/). Also, this issue led to duplicity vertices with the same XY coordinates but differ in Z coordinates.	2022-06-09 09:22:40 +02:00
