by the PlaceholderParser.
Namely, all the options with the "ratio_over" reference are now handled
correctly by the PlaceholderParser with the exception
of the "first_layer_extrusion_width", which overrides speed of extrusions
by their respective extrusion type.
Also the various extrusion widths (extrusion_width, first_layer_extrusion_width,
external_perimeter_extrusion_width etc.) produce the same numbers
as if ran through the back-end, with the assumption of not overriding
layer height by the variable layer height editing tool or layer height
modifiers.
slaposHollowing was divided into slaposHollowing and slaposDrillHoles on master
This commit takes this into account on the code that was merged from lm_drilling_backend_rebased
in place of the normal mesh.
WIP: The code is inefficient (it does not store the timestamp
of the hollowed mesh, therefore it refreshes the hollowed mesh on each
scene update) and if the hollowing gets invalidated, the original mesh
is currently not being reloaded and the hollowed mesh is still visible.
where the PrintObject bounding box was not invalidated correctly
when the transformation matrices of instances changed.
Also refactored PrintObject::size() for const correctness.
remove duplicate code
Mark conversion constructors of EigenMesh3D `explicit`
Working on mesh simplification for hollowed interior
Fix bug SPE-1074: crash with empty supports and disabled pad.
fix regression after refactor
Remove unfinished code
Fix missing includes and dumb comments
SPE-1072
Working but flipped normals with the interior.
Testing on treefrog passed
Oversampling for hollowed mesh should not be less than 3x
Flip back normals after simplify and remove redundant test code.
so that the ordering code at G-code export may work directly with
pointers to PrintInstances instead of with pair of <PrintObject, copy idx>.
Also the PrintInstance knows its source ModelInstance, which allows
sorting of PrintInstances for sequential printing in the order
they appear in Plater's object list.
