* CLI: --ground-face-* / --lay-flat / --center-on-bed orientation primitives
Adds the CLI counterparts to the GUI's lay-flat / face-pick gizmos.
Scripted / CI / AI pipelines can now set orientation without rendering
a wxWidgets frame; today the only way is a GUI round-trip.
New CLI actions (all operate in the mesh-local frame so they compose
with prior --rotate-* / --orient flags):
--ground-largest-face 1 Auto-detect the largest planar-face
or --lay-flat 1 cluster (area-weighted), rotate so its
normal points -Z. Covers "this part has
one obvious flat side" cases.
--ground-face-normal NX,NY,NZ Pick the face whose mesh-local
normal best matches the given
vector; ground it. e.g.
`--ground-face-normal 1,0,0`
stands a part on its +X side.
--ground-face-point X,Y,Z Find the triangle containing the
given mesh-local point; ground its
face. Disambiguates when several
faces share a normal (largest
containing triangle wins).
--center-on-bed 1 Translate so the XY bounding-box
centroid lands at the bed center
(derived from printable_area).
New file `src/slic3r/Utils/MeshOrient.{hpp,cpp}`:
- collect_triangles_object / compute_face_clusters — quantize
per-triangle normals (0.001, ~0.06°) and area-weighted-average
within clusters. Same clustering logic used by lay-flat.
- apply_ground_rotation — same math as Selection::flattening_rotate
in the GUI (Selection.cpp:1432): world-space quaternion from the
transformed normal to -Z, applied as offset * new_rot * old_no_offset
on every instance of every object, then a per-instance Z-lift so the
grounded face lands at exactly 0 (avoids "No layers were detected"
from FP-error z≈-1e-9).
- ground_face_point uses a top-N cluster search + point-in-triangle
test in local space; largest-area triangle wins on ambiguity.
Rationale: without these, any CLI pipeline that needs a specific
face on the bed must either encode custom rotation math per part or
break out of the pipeline into the GUI. Both are bad for
reproducibility. The --ground-face-* triple + the largest-face
auto-mode cover essentially every orientation intent expressible
in a slicing wizard.
Scope:
- `src/slic3r/Utils/MeshOrient.{hpp,cpp}` — new, ~420 lines
- `src/slic3r/CMakeLists.txt` — 2-line registration
- `src/libslic3r/PrintConfig.cpp` — 5 new CLIMiscConfigDef entries
- `src/OrcaSlicer.cpp` — 58-line handler block + 1 include
No behaviour change when the flags are absent.
(cherry picked from commit c45a9795e1)
* CLI grounding: choose among the Lay on Face planes, per object
Addresses review:
- Move the geometry of GLGizmoFlatten::update_planes() into
libslic3r/LayOnFace and use it from the gizmo and the CLI, so the
--ground-* options pick convex-hull faces per object and instance,
with part transformations (--rotate-x/y) applied.
- Drop --center-on-bed, the --lay-flat alias and MeshOrient; make
--ground-largest-face a coBool.
- Parse --ground-face-normal and --ground-face-point strictly. A point
that only some objects contain grounds those and leaves the others.
- Fold in --inspect-mesh from #14603, reporting the same planes.
- Tests in tests/libslic3r/test_lay_on_face.cpp: bounding boxes before
and after, rotate then ground, two objects, and a ribbed part whose
parallel inner faces outsum its base.
* CLI --inspect-mesh, --ground-face-*: reject missing input and empty values
- Without an input file or --load-assemble-list, --inspect-mesh printed
nothing and exited 0. Reject it up front with CLI_INVALID_PARAMS.
- An explicit empty --ground-face-normal or --ground-face-point was
silently ignored. Only options given on the command line reach the
transforms loop, so an empty value now fails the strict parse like any
other malformed value.
