reset timestamp to 1. This led to a bug where e.g. deleting painted facets
through the respective item in object list followed by possible other actions
and undo restored the painted facets from the time when the project was loaded.
I'm not sure if there was any other situation where this problem manifested.
Filtering of unprintable regions in multi-material segmentation depends on if gap-fill is enabled or not. So sliced object is invalidated when gap-fill was enabled/disabled by option "gap_fill_enabled" or by changing "gap_fill_speed" to force recomputation of the multi-material segmentation.
sets of optional boolean parameters, the cut function "keep upper",
"keep lower" and "flip lower" boolean parameters were converted into
a single type safe enum_bitmask. Such a coding style is certainly
wordier than the original code, but much safer and more readable
than the error prone "boolean, boolean, boolean" function call
parameter list.
config bundles, project files (3MFs, AMFs). When loading these files,
the caller may decide whether to substitute some of the configuration
values the current PrusaSlicer version does not understand with
some reasonable default value, and whether to report it. If substitution
is disabled, an exception is being thrown as before this commit.
If substitution is enabled, list of substitutions is returned by the
API to be presented to the user. This allows us to introduce for example
new firmware flavor key in PrusaSlicer 2.4 while letting PrusaSlicer
2.3.2 to fall back to some default and to report it to the user.
When slicing from command line, substutions are performed by default
and reported into the console, however substitutions may be either
disabled or made silent with the new "config-compatibility" command
line option.
Substitute enums and bools only. Allow booleans to be parsed as
true: "1", "enabled", "on" case insensitive
false: "0", "disabled", "off" case insensitive
This will allow us in the future for example to switch the draft_shield
boolean to an enum with the following values: "disabled" / "enabled" / "limited".
Added "enum_bitmask.hpp" - support for type safe sets of options.
See for example PresetBundle::load_configbundle(...
LoadConfigBundleAttributes flags) for an example of intended usage.
WIP: GUI for reporting the list of config substitutions needs to be
implemented by @YuSanka.
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.
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.
to help with detecting "not changed" event when taking
Undo/Redo snapshot or synchronizing with the back-end.
Converted layer height profile and supports / seam painted areas
to the same timestamp controlled structure.
1) Octree is built directly from the triangle mesh by checking
overlap of a triangle with an octree cell. This shall produce
a tighter octree with less dense cells.
2) The same method is used for both the adaptive / support cubic infill,
where for the support cubic infill the non-overhang triangles are
ignored.
The AABB tree is no more used.
3) Optimized extraction of continuous infill lines in O(1) instead of O(n^2)
