producing better shortest path estimate than the "closest next neighbor"
heuristics. The new greedy algorithm utilizes KD tree for closest
end point search, and builds a graph to detect loops.
PerimeterGenerator newly uses the optimized TSP algorithm.
ExtrusionEntity has been refactored / simplified.
1) Reworked void Plater::priv::reload_from_disk() to be more general
2) Added source data to class ModelVolume
3) Modified .3mf import/export to save/load volume matrices and source data
4) Incremented .3mf version to 2
of the Z coordinate, compiled in the ClipperLib_Z namespace.
Update of Lukas's new brim clipping:
All the brim contours are now clipped by the ClipperLib_Z library
in one shot.
to avoid layers thinner than min_layer height, and possibly due to
the fact, that empty support extrusions may get generated
for support layers with non-empty support polygons.
Fix of Empty layers detection added to GCode.cpp (6ab1cec)
Iterator loops replaced with C++11 loops.
Fixed clone() methods to return an ExtrusionEntity*.
PerimeterGenerator now uses move semantics on ExtrusionEntity a little
bit more.
All requested config values are written into SL1 ini file inside the zip
* TIme.hpp and Time.cpp is now part of libslic3r instead of libslic3r_gui
* Updated time manipulation function: separate timestamp_local_str and timestamp_utc_str
* timestamp_utc_str is used in header_slic3r_generated(). Gcode now contains UTC timestamps
The gap fill was disabled for zero infill.
Now the gap fill is enabled in between the perimeters, but disabled between
the inner-most perimeter and infill in case the infill is set to zero.
Also in case there are multiple infill regions inside a perimeter,
the mutliple infills are considered as non-zero if at least one infill
is non-zero, therefore the gap fill will be added inside the inner-most
perimeter.
In case there were empty object layers supposed to be floating on supports which were set to use a specific extruder, wipe tower was missing layer required to do the toolchange, leading to a crash
Such cases are now detected and layers that need it are additionally assigned as wipe tower layers
Also tracked as SPE-526
This can happen if the user enters invalid toolchange through the custom gcodes
Such toolchange is now simply ignored by the CoolingBuffer, exporting gcode is NOT stopped, a log error is emitted
