will be closed after triangle mesh slicing.
The value is set to 0.049 by default, which corresponds to the hard
coded default in Slic3r-1.41.3.
See issues #520#820#1029#1364 for the reference of why we need
the parameter for being able to print some specific models.
Sphere and Cylinder are scaled to the same volume as Box
Newly entered modifier meshes are rotated parallell to the world coordinates.
If the instance coordinate system is rotated and scaled, it is not possible
to create an unskewed modifier to world transformation. In that case
the best possible transformation is found to minimize least squares error
of the 8 corners of the new modifier mesh bounding box using
Levenberg-Marquardt algorithm.
FIXME:
1) The Levenberg-Marquardt non-linear least squares does not converge
nicely, it may require some tuning.
2) Above all, if 1) is called, then often the skew of the modifier mesh
is so high, that it is likely more useful to display the modifier
with zero rotation and inverse scaling, so that the modifier will be
of correct size, but not parallel to the world coordinates.
Refactored ModelVolume::Type to enum class ModelVolumeType to be able
to forward declare it.
Refactored UI to use the ModelVolumeType instead of the untyped int.
Fix of SLA gizmo picking by rectangle: point is occluded only if an object
is half its radius away from the point center.
Don't show the temp G-code file name in the status bar when exporting.
moved SLA print time estimation calculation into rasterization step,
so that the print time estimation is tracked by some SLAPrintStep.
Extended the output file name generator to use the SLA print statistics.
just the selected object.
Added "Host upload active" check on background processing state.
Documented requirements on "update_background_process" to
control the upcoming single "Slice Now" / "Export" button.
