stl_stats are newly only accessed by TriangleMesh::stats(),
most of the direct access to TriangleMesh::stl is gone with the exception
of parsing input files (3MF, AMF, obj).
on_is_selectable and on_is_activable functions are now completely independent,
the former says if there shall be an icon in the left toolbar, the latter
says if the gizmo can be activated (by a shortcut or GLGizmoManager::open_gizmo)
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.
The cracks were caused by using glPolygonOffset to resolve Z-fighting. All triangles of the object were firstly rendered entirely with a base color. And then paint triangles were drawn over these already rendered 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.
- Extra dialog for autosetting by angle in FDM supports gizmo was removed
- Highlighting facets by angle is now controlled by a slider in the main gizmo dialog
- User is allowed to paint even when using the slope highlighter
- The button to turn highlighted facets to blockers was removed, it made no sense
- Highlighted facets are now rendered in light blue
Obsolete variable m_clipping_plane was used instead of getting the clipping plane from
the common gizmo data pool. This means the clipped parts of objects captured hits and
could not be painted through.
The clipped_mesh_was_hit variable is obsolete now. It was a mistake to introduce it in the first place.
