There are several ExPolygons with very thin lines and holes formed by very close (1-5nm) vertices that are on the edge of our resolution. Those thin lines and holes are both unprintable and cause the Voronoi diagram to be invalid.
So, we filtered out such thin lines and holes and tried to compute the Voronoi diagram again.
Split Integrals constructor to accept polygon and polygons.
Add operator+(Integrals, Integrals).
Make sure extrusion extraction for integral calculation throws in invalid case.
In SupportSpotsGenerator there is a need to compute integral over
extrusions.
The mentioned function is slow for this use case. As it solves a harder
problem.
It is better to iterate the extrusion lines directly.
There was a test that relied on randomness and also checked the result
with very hight precision. That led to a failed test once upon a time.
Now the checking is more benevolent (it should be, as the code is
not expected to be precise) and also the randomness is removed.
SupportSpotsGenerator originally used a heuristic formula. Current
formula is properly derived using known properties of
second moment of area. Several tests of this formula are added.
WIP GCode/SmoothPath.cpp,hpp cache for interpolating extrusion path with arches.
Removed Perl test t/geometry.t, replaced with C++ tests.
Refactored ExtrusionEntity and derived classes to hold extrusion attributes in new ExtrusionFlow/ExtrusionAttributes classes.
Reworked path ordering in G-code export to never copy polylines, but to work with a new "flipped" attribute.
Reworked G-code export to interpolate extrusion paths with smooth paths and to extrude those smooth paths.
New parameters: arc_fitting, arc_fitting_tolerance
Renamed GCode class to GCodeGenerator
Moved GCodeWriter.cpp/hpp to GCode/
Moved Wipe from from GCode.cpp,hpp to GCode/Wipe.cpp,hpp
Moved WipeTowerIntegration from GCode.cpp,hpp to GCode/WipeTowerIntegration.cpp,hpp
New variant of douglas_peucker() to simplify range of iterators in place.
Refactored wipe in general and wipe on perimeters / hiding seams.
WIP: Convert estimate_speed_from_extrusion_quality() and its application to smooth paths.
WIP: Cooling buffer to process G2G3, disable arc fitting for filters that cannot process it.
