This is similar to an ExtrusionLoop, but it is open.
It may contain multiple chained paths with differing parameters.
This allows one to have a hierarchy of paths, where the ExtrusionEntityCollection
will be chained by the G-code generator, but ExtrusionMultiPath will not.
inside ClipperUtils are now using bit shifts instead of multiplication
by doubles, which makes the scaling precise.
Removed the scale parameter from all offset functions.
Modified the safety offset to calculate offset per polygon instead
of over all polygons at once. The old way was not safe and very slow,
sometimes this meant a kiss of death for supports for example.
These could be calculated from the fill areas if needed.
On the other side, the non-classified (non-split) fill areas are stored
now for use in the "ensure vertical wall thickness" feature,
also the non-split fill areas are re-used when recalculating the infills.
This is safer than trying to stitch the fill region together from the
classified fragments.
Modified the "ensure vertical wall thickness" feature to use the non-split
fill areas instead of perimeter areas for the calculation
of non-supported regions. This is cheaper as the fill areas contain
roughly half the edges.
Fixed some cracks in the fill surfaces created by rounding all surfaces inside detect_surface_type().
Fixed https://github.com/prusa3d/Slic3r/issues/12
Bridging-Angle not optimal
Extended the "Ensure veritcal wall thickness" mode (merged with the original discover_horizontal_shells function), but this a work in progress. Already Slic3r with "ensure vertical wall thickness" produces less spurious infills inside solids.
Crashes while switching in preview through layers with arrow keys
Also added a check box to visualize a single layer only
in the 3D path view. The check box may be toggled with a 'S' key.
Added shift+U / shift+D buttons in the 3D path view to show a single
layer only.
to return a string with an error message instead. This was necessary
to avoid a hang-up on some Strawberry Perl distributions, when
a perl "croak" function is called after a C++ exception is caught.
Replaced eval { die } construct with a bool return value indicating
success or failure of an automatic arrangement of parts on the print bed.
Don't know exactly what is happening here, but throwing a "die" inside
a XS function and then catching it inside an eval {} block is suspcious.
Removed dependency on Perl Math::PlanePath module.
Fixed compilation with Visual Studio and SLIC3R_DEBUG: Visual Studio older than 2015 does not support the prinf type specifier %zu. Use %Iu instead.
C++11 move semantics enabled.
Added "filament_max_volumetric_speed", a cap on the maximum volumetric
extrusion role, filament specific. This is very useful when mixing
rigid filament with a soft filament.
Extended the import / export of multi-string values into configuration
values, including the test cases. Multi-line strings will be enclosed
into quotes, quotes escaped using a C-style escape sequences. Single
word strings could still be stored without quotes.
if there is any valid option available. This feature has been asked for
by the Prusa3D customers as the '- default -' option has nothing to do
with the actual printer and when selected accidentally, it could even
lead to a printer damage.
Removed the deprecated VibrationLimit feature.
Added triangle infill.
The Prusa3D fork of Slic3r has been marked as "Slic3r Prusa Edition"
with menus pointing to the prusa3d/slic3r github release page
and Prusa3D drivers downloads page.
Made sure the C++ fillers are instantiated at the worker threads,
where there are being released.
Extended the FillRectilinear2 to calculate the contour / line intersection
with exact arithmetics, improved robustness and added error handling
and error reporting, if the contours to be filled are not correct.
Also a bug has been fixed for zero interface layers. Before
slic3r would put infinite number of interface layers over top surfaces,
if the number of interface layers was set to zero.
Don't arrange the objects on the build plate. The model coordinates
define the absolute positions on the build plate.
The option --print-center will be ignored.
Also there is a fix in the command line invocation of --duplicate-grid
so it will run, but still there is something broken there and the results
are not correct.
refreshed many times for a single move of the Z plane.
Fixes a problem on Windows, where the new wxWidgets always returned
Cancel, even if the window was closed with the "Cut" button.
Improved performance if the live preview is disabled or not needed,
because both top and bottom parts shall be displayed.
made configurable. Now one may hide the "controller" tab and the USB/serial
connection configuration from the preferences. This is useful for someone,
who never connects his printer to the computer by a cable.
The recent GCode writer changes which put the speed changes on a line of
their own have caused the layer time slowdown to be ignored by the regex
in CoolingBuffer.pm.
Fixes: #3134
