- better shrink (do not do all polygons in one go but per expolygon), now can be used for growth & shrink
- with multi-region, apply growths even if no hole growth
- stop pre-clip growth, it's a mess.
Next step is to do all that in one pass to avoid some problem with big growth/shrink
better import of 'elephant foot' (spelled elefant in prusa) that is now first_layer_size_compensation, using 'legacy to amke the convert.
advantage: it reverse the sign now.
drawback : no easy export to prusa.
fixes on ratio_over
fix Flow::extrusion_width (bad computation of first_layer_height)
fix enum visibility
moving test classes to prusaslicer test directory (wip)
all that because i was trying to write a test class for a modification in min_object_distance (and i didn't even start)
- now has a setting & a threshold
- when reverse_direction trigger on the external loop, it also trigger for all other loops on this side (so, no more U-turn)
- do not depends on extra_perimeter anymore
- now extra_perimeters split into extra_perimeters (the old useless one) and extra_perimeters_overhangs
- reordering settings in the tab.
Also some option to only apply to hole (or others)
Also some fixes to some loops options in the codepath.
also a test to thin walls, suspected a bug but can't find it.
if the number of top / bottom solid layers was set to zero while
the top / bottom minimum shell thickess was set nonzero.
With this commit, if the top / bottom solid layers is set to zero,
there are no top / bottom solid layers generated independent from
the minimum top / bottom shell thickness.
is enabled / disabled.
Spiral Vase forces different kind of slicing than the normal model:
In Spiral Vase mode, holes are closed and only the largest area contour is kept at each layer.
Therefore toggling the Spiral Vase on / off requires complete reslicing.
This commit moves the update to the correct location.
Fixes Connecting / expanding Bottom Layers to Vase Perimeter #253
Fixes Slicing error in vase mode #452
Fixes Slicing Issue (Vase Mode, 0.6mm dmr nozzle) #1887
Fixes Top fill pattern isn't used in spiral vase mode #2533
Fixes Cisar's vase doesn't slice correctly, creates artefacts #3595
When the model is sliced, all the contours are newly oriented
counter-clockwise (even holes), merged and then only the largest area
contour is retained. In perimeter generator, if the largest contour
splits into multiple perimeters, newly only the largest area perimeter
is retained in spiral vase mode. These two changes solve #3595 and similar.
The infill is newly calculated only for the bottom solid layers
if the spiral vase mode is active (removes various unwanted infill
along the vase walls), and the last bottom solid layer is switched
to a top solid pattern (solves #2533).
The thin walls are newly enforced to be disabled in spiral vase mode,
and the "ensure vertical shell wall" is enforced in spiral vase mode
to extend the bottom of the vase to the vase hull (fixes#253).
collisions against already printed objects: Rotation of an object
was not being taken into account.
Fixes#2450 PrusaSlicer 2.0 Sequential printing vs rotate object
Fixes#3585 Always Sequential Printing Error (Regardless of setting, placement or object size)
Fixed some collisions in sequential print just after arrangement by
making the validation using a slightly lower extruder radius value
than the arrangement.
Refactored PrintObject coordinate system so that the PrintObject's
coordinate system is always centered in respect to its ModelObject's
geometries. This refactoring may improve path planning a bit and
it may lower the requirements on bits representing Clipper coordinates
by 1 bit.
The two new config keys define a minimum vertical shell thickness.
The top shell thickness is calculated as a maximum of sum over
top_solid_layers * layer heights and top_solid_min_thickness,
the bottom shell thickness is calculated as a maximum of sum over
bottom_solid_layers * layer heights and bottom_solid_min_thickness.
The results of the formula above are shown at the Print parameter page
below the two new values to hint the user about the interaction
of the old versus new config values.
top_solid_min_thickness has no meaning if top_solid_layers is zero,
bottom_solid_min_thickness has no meaning if bottom_solid_layers is zero.
where the PrintObject bounding box was not invalidated correctly
when the transformation matrices of instances changed.
Also refactored PrintObject::size() for const correctness.
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.
Seam position default to corners (hidden) from "nearest", to avoid confusion when migrating from a prusaslicer config.
fix for modifiers with no_perimeter_unsupported_algo
npuaBridges surface fix
If the Elephant foot compensation is applied to the 1st object's layer,
the uncompensated 1st object's slice is newly used for calculation
of bridges, overhans, skirt, brim, raft and supports.
Layer::slices were renamed to Layer::lslices to simplify reading
of the code, to differentiate from LayerRegion::slices.
clean a bit some methods with newer c++
add more const to surfacecollection & create surfaceconstptr & a slice() method in layerregion that return const surfacecollection.
bugfix flow inaccuracies in FillSmooth.
TODO: do something about surface too small to be printed, particularly when 'only one perimeter top' -> don't extract them or use gapfill
Layer newly remembers bounding boxes of slices,
the bounding boxes are used by G-code generator & newly the support
generator.
Slices are stored as ExPolygons, not ExPolygonCollection.
