This was a regression of 2.4.0-alpha1 wrt. 2.3.3, where handling of
multiple volumes was refactored.
As a result, handling multi-part objects with clip_multipart_objects
disabled was broken.
With clip_multipart_objects disabled, the multi-part objects no more
clip one another and it is sole responsibility of the user to handle
overlaps.
Fixes "add part" error - PrusaSlicer 2.4.0 b2 #7366
This is a regression wrt. to PrusaSlicer 2.3.3 due to refactoring
of the slicing process for better multi material support
and to support negative volumes.
see pull request #7323 for discussion what went wrong.
The original issue
Fix of Print::apply() creating hierarchy of regions for complex scenarios:
Unnecessary regions were created for a modifier over a volume or a modifier,
where the modifier did not modify any of its parent's properties.
This lead to an explosion of regions for this particular 3MF.
Fixes Non Responsive & Memory Leak when opening or changing this 3MF project #7220
After a0ee41770d
quite often regions were not re-regenerated. This shoul now be fixed
together with the original slowness & memory leak issue.
(Fixed missing sinking property in objects list for multipart objects
with a part completely below the printbed):
It was not possible to slice an object with some part completely below
the print bed. The BuildVolume collision check newly supports
a "completely below print bed" return status,
Model evaluates this "completely below print bed status" allowing
objects with some volumes completely below the print bed to print.
circular, convex, concave) and performs efficient collision detection agains these build
volumes. As of now, collision detection is performed against a convex
hull of a concave build volume for efficency.
GCodeProcessor::Result renamed out of GCodeProcessor to GCodeProcessorResult,
so it could be forward declared.
Plater newly exports BuildVolume, not Bed3D. Bed3D is a rendering class,
while BuildVolume is a purely geometric class.
Reduced usage of global wxGetApp, the Bed3D is passed as a parameter
to View3D/Preview/GLCanvas.
Convex hull code was extracted from Geometry.cpp/hpp to Geometry/ConvexHulll.cpp,hpp.
New test inside_convex_polygon().
New efficent point inside polygon test: Decompose convex hull
to bottom / top parts and use the decomposition to detect point inside
a convex polygon in O(log n). decompose_convex_polygon_top_bottom(),
inside_convex_polygon().
New Circle constructing functions: circle_ransac() and circle_taubin_newton().
New polygon_is_convex() test with unit tests.
Activates only if PrusaSlicer.ini does NOT contains any FFF printers.
Added only_default_printers() function to activate wizard if none printers are installed.
- Unified preferences settings. version_check option is replaced with notify_release that has 3 states.
- fixed logic when show notification based on version string.
- notification shows released version
- dialog notifying new version is never showing if external updater is running.
Escape quotes inside path to external updater
+ Added nsvgParseFromFileWithReplace() to replace some colors before parsing from SVG file
+ Thumbnails are saved with selected resin color in SL1 or SL1S files
+ "white" folder is deleted from "icons" now. THere is no needed anymore.
Previously, colored polygons were stored so that each polygon had a color assigned to it, which made it difficult to perform operations like union or so on all polygons of the same color. Now polygons are stored grouped by their assigned color/extruder.
* Refreshed title bar for all Dialogs and MainFrame
* Refreshed header of the DataViewCtrl and ListView
* Refresh tooltips
* Redraw SpinCtrls
* Use system menu with is colored in respect to the color mode
* Preferences: Added parameter "Use system menu for application" and moved to the "Dark mode" tab with "Enable Dark mode parameter"

"with sheath" now again uses the lighweight zig-zag algorithm
for the sparse support columns, while PrusaSlicer 2.4.0-alpha1
to PrusaSlicer 2.4.0-beta1 used the new "stable" zig-zag
algorithm for both the non-sheathed and sheathed sparse support columns
creating unnecessarily thick support column perimeters.
{num_objects} - number of printable objects on the plater.
{num_instances} - number of printable instances on the plater, adding up
all printable instances of all objects.
Implements #2735#3339#4607
round() rounds to an integer.
This is a popular request, for example #3472
digits(value, num_digits, num_decimals) rounds to num_digits and
num_decimals, left filled with spaces.
digits(value, num_digits) the same as digits(value, num_digits, 0)
Neither decimal separator nor any decimals after decimal separator
are emitted.
zdigits(...) is the same as digits(...) only left filled with zeros.
If the result does not fit num_digits, the result is never trimmed.
support blockers / enforcers.
All slicing functions shall produce consistent results with the same mesh, same transformation matrix and slicing parameters.
Namely, slice_mesh_slabs() shall produce consistent results with slice_mesh() and slice_mesh_ex() in the sense, that projections made by
slice_mesh_slabs() shall fall onto slicing planes produced by slice_mesh().
Before this commit, slice_mesh_slabs() projected bottom facing faces upwards to its coplanar slicing plane,
which is different from how slice_mesh() or slice_mesh_ex() work, leading to ignored support enforcer / blocker strokes.
interface layers if possible. This should always be possible with
soluble supports and it should have been done long time ago.
For non-soluble supports, it may or may not be possible to merge
these layers: They will only be merged if they are extruded without
bridging and with the same layer height.
Fixes Support enforcer interfaces not generated as needed. #6784
or at least some of the issues reported.
Experimental: Added experimental filtering of propagated support columns
to two extrusions, overlapping by maximum 20%.
This filtering step will remove spurious columns that do not support
anything, but the filtering step may remove supports supporting tiny
islands. Those supports would likely not be printable anyways without
the user intervention (extending the supported area by painting).

The line end positions were not extracted correctly from G-code
imported into a stand-alone G-code viewer.
flip direction of the infill layer with each interface layer.
Unfortunately the flipping of support interface directions may not work
reliably due to base support layer heights growing at different rate
from the interface layers.
for offset2() with clear meaning.
New ClipperUtils functions: expand(), shrink() as an alternative
for offset() with clear meaning.
All offset values for the new functions are positive.
Various offsetting ClipperUtils (offset, offset2, offset2_ex) working
over Polygons were marked as unsafe, sometimes producing invalid output
if called for more than one polygon. These functions were reworked
to offset polygons one by one. The new functions working over Polygons
shall work the same way as the old safe ones working over ExPolygons,
but working with Polygons shall be computationally more efficient.
Improvements in FDM support generator:
1) For both grid and snug supports: Don't filter out supports for which
the contacts are completely reduced by support / object XY separation.
2) Rounding / merging of supports using the closing radius parameter is
now smoother, it does not produce sharp corners.
3) Snug supports: When calculating support interfaces, expand the projected
support contact areas to produce wider, printable and more stable interfaces.
4) Don't reduce support interfaces for snug supports for steep overhangs,
that would normally not need them. Snug supports often produce very
narrow support interface regions and turning them off makes the support
interfaces disappear.
Fixed crash with zero support base spacing.
The bug fix was not correct and it disabled the new "zig-zag" sparse
infill generator, leading to GH issue #7014
Somehow improved missing interface layers for snug supports
by propagating full overhangs when generating interface layers.
Fixed generation of soluble interfaces for support enforcers,
where base support was used for steeper overhangs.
Disabled filtering out thin regions from the lower layer, that will
not be covered by perimeters, thus they are not supporting the current layer.
However this may lead to a situation where regions at the current layer
that are narrow thus not extrudable will generate unnecessary supports.
For example, see GH issue #3094
* Fixed update of a warning icon for multi-part object, when some part with errors was deleted
* Fixed a crash when selecting non-Object and non-Volume item (in get_mesh_errors_info() was missed check of the obj_idx)
+ Follow-up 1cc7b4ba97 - some code refactoring:
* fixed RepairedMeshErrors.merge()
* get_mesh_errors_count() renamed to get_repaired_errors_count()
with their original names. Using weird shorthands makes the code
unreadable for anyone but the original author.

There was a bug for more than 4 years, which likely triggers now more
often with the introduction of raft_contact_distance parameter,
which is usually significantly smaller than support_material_contact_distance.
There were no support towers built at the raft for contact layers
below the print_z of the first object layer.
