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.
