for islands with another islands in their holes.
Improvement of chaining of infill lines for 3D honeycomb, Gyroid and
Honeycomb infill: New TSP chaining algorithm is used.
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
