Renamed its_create_neighbors_index() / its_create_neighbors_index_par() to its_face_neighbors() / its_face_neighbors_par().
New variant of its_face_edge_ids() to create edge IDs from face neighbors.
Fixed some incorrect use of _NDEBUG, it should be NDEBUG.
PrintObject::slice_support_volumes() returns newly Polygons, which are cheaper than ExPolygons.
Updated SeamPlacer and SupportMaterial to use regions defined as Polygons, not ExPolygons.
TriangleSelector::get_facets_strict() returning a patch with T-joints retriangulated.
New slice_mesh_slabs() - slicing projections of a triangle patch into top / bottom layers of slices, for MMU top / bottom segmentation.
TriangleMeshSlicer - use 64 mutexes instead of one when scattering sliced triangles into layers. This makes a big difference on modern many core desktop computers.
When applying MM segmented regions to input regions, the split regions are now re-merged with 10x higher positive offset epsilon to avoid creating gaps.
When testing for existence of paint-on supports or seam, use a more efficient has_facets() test, which does not deserialize into the expensive TriangleSelector tree structure.
GLIndexedVertexArray newly uses Eigen::AlignedBox<float, 3> for efficiency instead of our double based BoundingBoxf3.
Improved MMU painting refresh speed by optimizing generation of the vertex buffers.
Refactored MMU segmentation - projection of painted surfaces from top / bottom.
1) Parallelized.
2) Using the new slice_mesh_slabs() instead of projecting one triangle by the other and merging them with Clipper.
1) Fixing yesterday's regression in deserialization of older painted 3MFs
(order of triangle children is now reversed, thus the serialization
/ deserialization has to take it into account).
2) WIP extraction into facets to triangulate T-joints.
1) When splitting a triangle, vertices are now properly shared with
the neighbor triangles, if these are already split.
Please note that the splitting may not be regular if the splitting
thershold is changed between splitting calls. Still the new code
shares the vertices accross shared edges properly.
2) Triangles resp. vertices are newly reused after deleted using
linked lists of released triangles resp. vertices.
This mechanism replaces the old mechanism of reusing already split
triangles.
TriangleSelector::valid refactored to m_valid and valid()
and bool members moved next to each other to shrink data structure
size due to memory alignment.
Changed the serialization structure
std::map<int, std::vector<bool>>
to a significantly more compact
std::pair<std::vector<std::pair<int, int>>, std::vector<bool>>
Such change shall significantly improve efficiency of Undo / Redo stack.
S3D's strategy for merging self intersecting models is "Even / Odd"
which PrusaSlicer now supports as an alternative to "Positive" rule.
Also added a "Close Holes" option to fill in all internal structures.
3D-Labprint Models aren't sliceable (till years) #3062#3708
Newly the PrintObjects own PrintRegions and Print contains references
to PrintRegions owned by PrintObjects, so that a PrintRegion of the same
content is referenced by Print only once.
The refactoring is a WIP to support multi-material painting.
Fixes Solid infill where there should be none #6482
Also the safety offsetting was revised to be enabled only where needed,
the "do safety offset" is now easy to discover by
a new ApplySafetyOffset::Yes enum, and safety offset over union, which
is better done by offset() / offset_ex() has been replaced with
new union_safety_offset() / union_safety_offset_ex() functions, which
better convey their meaning and which could be better optimized than
union() with the safety offset applied.
which was broken with 68666de521b1cb15e41ac6728c0e8d3b4b0d4ed0
"Reworked the "new" bridging to respect the bridge_flow_ratio
by maintaining extrusion spacing, but modifying the extrusion width
and / or height."
from the background slicing thread, that supports cancellation.
The generic mechanism is used for generating thumbnails into G-code and
Fixes Fix deadlock when canceling the slicing while gcode is creating thumbnails #6476
Thanks @supermerill for pointing out the issue.
