* CrossSection API break (#1707): fix WASM JoinType::Bevel
'Bevel' was registered in the embind enum but missing from the
TypeScript type and from joinTypeToInt(), so passing 'Bevel' silently
fell through to 'Square' (0). Add it to both.

* CrossSection API break (#1707): tolerance API fixups
- Rect and Circle constructors now set tolerance_ via InferEps,
consistent with the Polygons constructor. Previously GetTolerance()
returned 0 for these paths.
- Hull(const SimplePolygon&): use the local sorted copy (points) for
InferEps, not the original const-ref (pts).
- Move SetTolerance declaration to the Information doxygen group
alongside GetTolerance.
- Add CBIND.cross_section_tolerance smoke test for
manifold_cross_section_get/set_tolerance.
- Fix stale comment in SimplifyPostFiltersBoolean2Output referencing
the old epsilon=1e-6 default.

* CrossSection API break (#1707): fix WASM compose/voronoi, doc Simplify default
- Remove 'compose' from crossSectionStaticFunctions in garbage-collector.ts
(CrossSection.compose no longer exists; wrapping undefined crashed with
"originalFn is not a function" in WASM TBB:OFF CI lanes)
- Add 'setTolerance' to crossSectionMemberFunctions (returns new CrossSection)
- Update voronoi.mjs to use CrossSection.union() instead of .compose()
- Fix stale @param epsilon / default 1e-6 in manifold-encapsulated-types.d.ts
(parameter is now 'tolerance', default 0 uses the geometry's own tolerance)
- Add @param doc note to CrossSection::Simplify explaining that default 0
resolves to tolerance_ (geometry-scale-derived, not a fixed 1e-6)

* Add Manifold::Contains and Manifold::WindingNumber
Closes#1440.
Implements point-in-mesh containment testing via the Boolean winding
number kernel (Kernel02) already used by the CSG operations, giving
correct results for non-simply-connected shapes and overlapping regions
where simple ray-parity would be wrong.
Core: Manifold::Impl::PointWinding in boolean3.cpp
- Builds a minimal Impl for the query points (vertPos + zero normals)
- Pre-filters with the 3D bounding box - points outside return 0 immediately
- Queries the BVH with vec3 points, which triggers DoesOverlap(vec3) - an
XY-projected check - so all faces with XY overlap are returned regardless
of Z, enabling correct +Z winding accumulation above the query point
- Processes all points in a single parallel BVH traversal
Public API (include/manifold/manifold.h, src/manifold.cpp):
- int WindingNumber(vec3 point) const
- std::vector<int> WindingNumber(const std::vector<vec3>& points) const
- bool Contains(vec3 point) const
- std::vector<bool> Contains(const std::vector<vec3>& points) const
Bindings: C (scalar), Python (scalar + batch), WASM (scalar + TypeScript types)
Tests (test/measurement_test.cpp):
- ContainsTallBox: verifies XY-projected collider query (would fail with 3D Box)
- WindingWatertight: no double-counting at shared edges/vertices
- WindingHollowShell: real winding number, not just ray parity
- ContainsBatch: batch results match scalar for all points
- WindingMatchesRayCastParity: cross-checked against existing RayCast
* Fix clang-format violations and nanobind overload_cast in Python bindings
nanobind requires static_cast for overloaded member functions;
nb::overload_cast without return type doesn't resolve ambiguity.
Also wrap long comment lines to satisfy clang-format 20.
* Simplify winding number API
Remove scalar WindingNumber(vec3) and all Contains overloads from C++,
C, Python, and WASM bindings.
Rename `active` to `query2input` in PointWinding.
Plumb the
vector API through WASM instead of the previous single-point calls to
avoid per-point marshalling overhead.
* Fix clang-format-lint errors
The ctx-aware static factories (FromMeshGL / LevelSet / Smooth) had no
binding, so ops with no source Manifold to attach via WithContext - notably
MeshGL ingest - could not be observed or cancelled from the language
bindings. The ExecutionContext object and WithContext were already bound;
this adds the three factories as methods on the context, mirroring the plain
static factories.
- C: manifold_execution_context_{level_set,level_set_seq,of_meshgl,
of_meshgl64,smooth,smooth64}. The level_set helper is generalized to run
under an ExecutionContext; the SDF callback user-data is renamed sdf_context
to keep it distinct from the ExecutionContext argument.
- Python: ExecutionContext.{from_mesh,level_set,smooth} mirroring the
Manifold static-factory lambdas.
- WASM: ExecutionContext.{fromMesh,smooth,levelSet} (embind helpers in
helpers.cpp, JS wrappers in bindings.js, .d.ts declarations).
Tests: CBIND.execution_context_factories (C), all_apis.py coverage (Python),
and an ExecutionContext-static-factories case (WASM). All build and pass
locally across the three layers.
Toward #971.

* Record normals on Manifold; auto-substitute on GetMeshGL; roundtrip via MeshGLP
Following Emmett's #1712 direction: make "where are my normals?" a
property of the Manifold rather than something the caller threads
through every call. After CalculateNormals(), GetMeshGL() returns
solid-frame normals without needing the idx repeated; an ofMesh ->
getMesh roundtrip preserves the recording via a new optional
MeshGLP::hasNormals flag.
The standard slot is the first three extra-property channels (MeshGL
channels 3, 4, 5). CalculateNormals / SmoothByNormals / UpdateNormals
gain default normalIdx values (0 / 0 / -1 respectively) so the no-arg
call is the new preferred form; non-zero values are kept for
compatibility but flagged in the docs. Refine clears the recording
(interpolated normals are wrong).
Bindings updated in lock-step: Python (nb::arg defaults, has_normals
field on MeshGL/MeshGL64), WASM (JS wrapper for smoothByNormals,
helpers.cpp roundtrips hasNormals, .d.ts type updates), C (
manifold_meshgl{,64}_has_normals accessors). Single-signature shape
means no overload disambiguation needed in any binding.
Open follow-ups: [[deprecated]] attribute + internal caller migration,
SetProperties detection (flagged with TODO).

* Record normals on Manifold; auto-apply transforms via runFlags bit 1
Fixes#1712, fixes#1719.
Make "where are my normals?" a property of the Manifold rather than
something the caller threads through every call. After CalculateNormals,
GetMeshGL returns world-frame normals without an explicit normalIdx, and
a MeshGL <-> Manifold round-trip preserves the recording per-run even
across mixed-input Booleans (e.g., a cube without normals composed with
a sphere that has them).
The #1712 repro from
(sphere - sphere.Translate(10)).CalculateNormals().GetMeshGL()
now returns the expected outward-from-cavity normals. The underlying
cross-mesh seam-vert sign issue (#1719) is fixed in SetNormals.
Mechanism:
- runFlags becomes a bitmask: bit 0 = backside (existing), bit 1 =
hasNormals (new). New MeshGLP::HasNormals(run) accessor mirrors
Backside(run). Backside fixed from `runFlags[run] == 1` to `& 1` so
it survives the addition of a second bit.
- CalculateNormals(0) marks the per-meshID Relation.hasNormals flag,
which Impl::HasNormals() ANDs across to give the impl-wide answer.
GetMeshGL(-1) auto-substitutes slot 0 on output when HasNormals() is
true.
- Normals at the standard slot are stored world-frame on the Impl.
Impl::Transform and csg_tree.cpp::Compose eager-transform
properties_[0..2] per-meshID so the slot stays in sync with vertPos_
and faceNormal_ across any sequence of transforms, including mixed-
input Boolean/Compose outputs where some meshIDs carry normals and
others don't. EagerTransformPropNormals is a shared helper.
- SetNormals multi-normal walk sign-flips cross(next, here) when it
disagrees with faceNormal_[next.face]. This handles Boolean
subtractee triangles (winding unchanged, faceNormal_ negated by the
Boolean post-pass) without losing the existing "flair" curving for
smooth surfaces. This is what fixes#1719.
- CreateProperties negates Q's slot 0..2 per source-meshID for
subtractee cavity inversion.
- GetNormal returns properties_[0..2] directly when the meshID's
Relation.hasNormals is true (world-frame already); applies the per-
meshID inverse-normal-transform when false, preserving the master
contract for hand-built MeshGL inputs that don't set the bit.
- Non-zero normalIdx to CalculateNormals uses the legacy deferred-
transform path: stores per-mesh-frame, recovered to world-frame by
GetMeshGL's per-run transform on export. Docstring notes this path
will be removed in a future release.
API additions:
- MeshGLP::HasNormals(run) C++ accessor plus C and Python bindings.
- MeshGLP::Backside(run) C and Python bindings (previously C++-only).
Tests:
- Properties.CalculateNormals: previously-FIXME'd dot(pos, norm) > 0
asserts enabled (#1719 regression).
- Manifold.CalculateNormalsRoundTripsThroughGetMeshGL: ofMesh+getMesh
preserving the per-run flag, Rotate before and after CalculateNormals,
no-arg invocation, non-zero idx.
- Manifold.GetNormalLegacyContract: per-mesh-frame fallback in
GetNormal for MeshGLs without bit 1.
- Manifold.TransformMixedNormalsPerMeshID,
Manifold.ComposeMixedNormalsPerMeshID,
Manifold.BooleanSubtractMixedQPerMeshIDNegation: per-meshID iteration
in Impl::Transform / Compose / CreateProperties for mixed-input
Boolean outputs.
- Manifold.CalculateNormalsNonZeroIdxSurvivesTransform: legacy non-zero
normalIdx path across post-calc transforms.
- CBIND.run_flag_accessors: exercises the new C accessors.
Known limitations:
- Hand-built MeshGL inputs that share propVerts across runs with
differing hasNormals settings produce one-interpretation-wins
behavior at the shared propVerts (the stored value can only have one
semantic). Standard CalculateNormals / Boolean / Compose outputs
never produce this shape. Documented on MeshGLP::HasNormals(run).
- Warp / WarpBatch / SetProperties keep the recording set; if the user
replaces slot 0..2 or warps non-rigidly, the stored normals are stale
until they call CalculateNormals again. Documented on each method.

* Address PR #1718 review feedback
Substantive:
- Split CalculateNormalsRoundTripsThroughGetMeshGL into 8 named tests
(NormalsCavity, NormalsRotateBefore/AfterCalc, NormalsAutoSubstitute,
NormalsRoundTrip, NormalsRefinePreserved, NormalsSmoothByNormalsNoArg,
NormalsNonStandardSlotNotRecorded). Pithier names per Emmett's request.
- Fix Backside(run) docstring: framework already orients stored normals
on the standard flow, the bit is informational only.
- SafeNormalize during the eager-transform in
Manifold::Impl::EagerTransformPropNormals so non-orthogonal transforms
and barycentric interpolation don't leave non-unit values that compound
downstream (e.g., at Boolean edges feeding SmoothByNormals).
- Add `backside(run)` and `hasNormals(run)` methods on the WASM Mesh
class, plus runFlags field documentation in the .d.ts.
- Add a deliberately-failing test (NormalsSharedPropVertMixedFlags) that
demonstrates the data-model conflict in the shared-propVert + mixed-
hasNormals case. Hand-built MeshGL inputs with shared propVerts across
runs of differing hasNormals can only store one slot 0..2 value;
Impl::Transform picks one interpretation, corrupting the other. Test
is intentionally red as a discussion-driver for PR #1718 review
thread (whether to fix by splitting propVerts in the Manifold(MeshGL)
ctor, or to document the constraint).
Trivial:
- Rename wasHasNormals -> hadNormals in Impl::InitializeOriginal.
- Drop verbose eager-transform comment block in Impl::Transform; the
helper call site is self-documenting.
- Note AND-not-OR semantics on Impl::HasNormals(); rename hint covered
by the new doc.
- TODOs at the legacy non-zero-normalIdx codepaths (the getTransform
lambda in SetNormals, the legacy fallback in GetMeshGLImpl per-vert
normalization) marking them for removal alongside the deprecated API.
- Deprecation notice on GetMeshGL/GetMeshGL64's explicit normalIdx
parameter.

* Split shared propVerts across runs with mixed hasNormals
Addresses comment 3254084222 on PR #1718. When a single input propVert
is referenced by triangles from runs with differing hasNormals flags,
the eager-transform contract can't track both interpretations through
one slot 0..2: a Transform would rotate the hasNormals=true run's
normal and corrupt the hasNormals=false run's color (or vice versa).
The MeshGL ctor now duplicates such propVerts so each camp gets its
own slot. The first-seen camp keeps the original index; the opposite
camp gets an appended alt copy holding a snapshot of the original
property data. Subsequent triangles from each camp resolve through
their respective indices. DedupePropVerts already skips cross-meshID
pairs, so the duplicate survives ctor cleanup, and
EagerTransformPropNormals is gated on TriHasNormals per triangle, so
only the hasNormals camp's copy gets rotated.
Behaviour preserved for the existing numProp == 0 cases (the
single-array legacy push pattern is retained when there's no distinct
prop space). For numProp > 0 we always populate both triProp and
triVert now - prior code skipped triVert when prop2vert was empty, but
the split can introduce triProp values >= numVert that need triVert
for valid v0/v1 in CreateHalfedges.
Docs: re-add a paragraph to MeshGLP::HasNormals (and the WASM
hasNormals method) describing the auto-split, replacing the
"undefined for hand-built mixed-flag inputs" caveat that ce0e18d8
removed when it staged the failing test.
The new test NormalsSharedPropVertMixedFlags (added in ce0e18d8 as a
discussion-driver red test) now passes; its docstring is updated to
describe the fix rather than the failure.

* Revert "Split shared propVerts across runs with mixed hasNormals"
Per discussion on PR #1718 (review comment 3254084222): the shared-
propVert + mixed-hasNormals input shape is genuinely weird (no standard
output produces it) and adding the auto-split to every MeshGL ingest
slows the import path - already a sore spot relative to Boolean - and
adds maintenance surface for a case users shouldn't be hitting.
Reverting cf8d898a (the split implementation + doc changes) and ce6e394a
(the clang-format follow-up that touched the same block). Test wording
and updated doc explaining the constraint follow in a separate commit.

* Document undefined behavior for cross-run shared propVerts
Add a caveat paragraph on `MeshGLP::HasNormals` (C++ header) and the
WASM `hasNormals(run)` method noting:
- hasNormals is per-run, so different runs may set it differently
(leading with this since the original removed-then-not-restored caveat
was misread on review as forbidding mixed-flag runs).
- Behavior is undefined when a single propVert is shared by triangles
from runs that disagree - a Transform rotates the slot on behalf of
the hasNormals=true camp and clobbers any hasNormals=false sharer.
- Standard CalculateNormals / Boolean / Compose outputs never produce
that shape - hand-built MeshGL inputs are the only way to hit it.
Repurpose the `NormalsSharedPropVertMixedFlagsUndefined` test (renamed
from `NormalsSharedPropVertMixedFlags`) to pin the documented
behaviour: assert the hasNormals camp's slot rotates as expected
(`run0Bad == 0`) and the no-normals camp's value is clobbered
(`run1Bad > 0`).

* Attach ExecutionContext to Manifold; remove per-call Status(ctx) variant
Replaces the per-call ExecutionContext parameter on Status() with a
data-attachment model: WithContext(ctx) returns a copy of the Manifold
with the context attached, and the no-arg Status() routes through any
attached context. Subsequent operations on the attached Manifold (and
the Manifolds they derive) inherit the attachment, so Translate,
Boolean, Hull and friends observe progress and cancellation without
needing extra parameters.
The attachment travels with the data: copying propagates it, and ops
returning a Manifold inherit from the primary operand (`*this` for
member ops, `manifolds[0]` for the static factories that combine
multiple Manifolds). WithoutContext() detaches; GetContext() returns
the attached context as std::optional<ExecutionContext> sharing state
with the original.
Removes the explicit Status(ExecutionContext&) overload from C++ and
its matching forms in the C / Python / WASM bindings
(manifold_status_with_context, .def("status", ctx), statusWithContext)
in favour of attach-then-Status(). Refine variants are left untouched
in this commit; that's the next one.
* Refine: route attached ExecutionContext through Subdivide post-pass (#1702)
The motivating example for per-call ctx parameters (PR #1702) was
mid-Refine cancellation. With ExecutionContext now attached to the
Manifold, that need can be served without changing public signatures.
Adds an optional ctx parameter to Manifold::Impl::Refine and threads
the cancel check between Subdivide and the post-pass
(SetNormalsAndCoplanar / CalculateVertNormals / SortGeometry), routing
SortGeometry through its existing ctx-aware overload. The public
Refine, RefineToLength and RefineToTolerance variants pass ctx_.get()
both into GetCsgLeafNode (input-tree evaluation) and into Impl::Refine
(post-Subdivide work).
Subdivide itself stays cancel-blind for now; the cancellation point is
at the granularity of "after Subdivide returns", which matches how
other ops in the codebase observe cancellation around their hot kernel.
* Refactor: collapse construct+inherit pattern into Derived() helper
Member ops returning a derived Manifold previously did:
Manifold result(...);
result.InheritContextFrom(*this);
return result;
Replace with a templated private helper `Derived(T&& arg)` that
forwards `arg` to the appropriate Manifold ctor and inherits the
attached ExecutionContext from `*this`. Static factories that combine
multiple Manifolds use the lvalue form, e.g. `manifolds[0].Derived(...)`.
Templated to forward through shared_ptr-of-derived-CsgNode (e.g.
shared_ptr<CsgLeafNode>) which would otherwise need two user-defined
conversions to reach Manifold.
No behavior change. Saves ~40 lines across 17 call sites.
* Pivot ExecutionContext attach to "eager-reads-input, deferred-drops"
Per #1704 review: ctx is consumed only by the next eager op invoked
on the result (Status, Refine family). Deferred ops (Boolean,
transforms, batch ops) ignore any attached ctx; their result has no
ctx. Raw copy/assignment preserves the attachment.
Public surface trimmed to one method per binding (C++ With,
manifold_with_context, with_context, withContext); WithoutContext /
HasContext / GetContext and their mirrors are dropped -- under the
new model the user always knows what ctx they attached, so
introspection has no real use case. Internal Derived() helper and
InheritContextFrom go with the inheritance step; call sites use
plain Manifold(...) construction.
Test flips: deferred ops drop input ctx; Refine result has no ctx;
copy/assignment preservation checked behaviorally via Status()
routing rather than HasContext.
395/395 pass (was 397; net -2 dropped + 1 new test for the
(a+b).With(ctx).Status() idiom).

* Cleanups around ExecutionContext attach
- Fix `Manifold(Manifold())` wart in `Mirror`'s degenerate-normal branch
(search-and-replace leftover from collapsing the old `Derived(...)`
helper into plain `Manifold(...)` construction). Should be just
`Manifold()`.
- Remove dead `ExecutionContext(std::shared_ptr<Impl>)` ctor: it was
used by the now-removed `GetContext()`. No live callers.
- Tighten the `With(ctx)` docstring to explicitly close the list of
ctx-observing ops -- `Volume` / `GetMeshGL` / `BoundingBox` etc.
force evaluation but do not currently observe attached ctx. The
previous wording was positive-only and could mislead a casual reader.

* Rename C++ `With` -> `WithContext` to match bindings
The bindings use `with_context` (C, Python) / `withContext` (WASM); the
C++ method had been the asymmetric shorter `With` on the rationale that
C++ overload resolution future-proofs the verb. Per Emmett's review on
#1704, the consistency tradeoff is small enough that matching the
bindings is the cleaner outcome.
Mechanical rename across 8 files (header decl, impl, bindings, tests,
docstring prose). No semantic changes.

* Drop redundant Manifold(...) wrap around Minkowski return
`Impl::Minkowski` already returns a `Manifold`; wrapping it just invokes

* Add ExecutionContext language bindings
Mirrors the C++ ExecutionContext API (from #1663) in the C, Python, and
WASM bindings:
- C: opaque ManifoldExecutionContext with manifold_execution_context{,_
cancel,_cancelled,_progress} and manifold_status_with_context; full
size/alloc/destruct/delete plumbing.
- Python: ExecutionContext class with cancel/cancelled/progress; Status
overload via nanobind overload dispatch.
- WASM: ExecutionContext embind class with the same methods; new
Manifold.statusWithContext(ctx) that delegates to a shared
ErrorToString helper (and adds the previously-missing Cancelled case).

* Add real Python cancel assertion to all_apis.py
The pre-existing ExecutionContext block in all_apis.py was a smoke test

evaluation entirely) and didn't assert the result. Add an assertion
using a CsgOpNode (Manifold.cube() + Manifold.sphere(1)) so a
regression in the Python status(ctx) overload — like the nanobind
overload-resolution break that tripped CI once during #1668 dev —
would actually fail the test.

ambiguous in nanobind's .def() call. Cast to the no-arg overload
explicitly; the new overload is not yet exposed in bindings.

* Guard std::thread tests behind MANIFOLD_PAR == 1
Emscripten/WASM builds without pthreads cannot construct std::thread
and abort at runtime. The two tests that spawn a side thread to
observe progress or trigger cancellation mid-evaluation aren't
meaningful on a non-parallel build anyway — evaluation is synchronous.

* Address #1663 review: iterative NumLeaves, poison stack on cancel, docs example
- NumLeaves: rewrite iteratively. Recursive version could stack-overflow
on deep CsgOpNode trees (e.g. `m += m1 += m2 += ...` chains), which
is the exact case the existing iterative ToLeafNode was written for.
- ToLeafNode cancel: poison every op_node currently on the stack, not
just `this`. A sub-op may have had its impl_ partially mutated during
its finalize (children replaced with an intermediate result); leaving
its cache_ unset would let a later evaluation of a shared sub-op run
against the partially-reduced tree. All frames now share one
ErrorLeaf(Cancelled), which is safe because the empty-cancelled Impl
is transform-invariant for error-status queries.
- ExecutionContext docstring: add a concrete observer-thread example.

* Relax Minkowski test tolerances for cross-platform consistency
The NonConvexConvexMinkowski and NonConvexNonConvexMinkowski tests had
tight tolerances (1e-5) that fail due to minor numerical variations
across platforms. Widened surface area tolerances to 1e-2 and volume
tolerances to 1e-3 to account for triangulation differences.

* Fix Minkowski test CI failures
- Add processOverlaps=true to ConvexConvexMinkowskiD to handle
duplicate/collinear points in triangulation
- Disable NonConvexNonConvexMinkowski test - produces non-manifold
results on some platforms due to coplanar face handling issues
in the naive Minkowski implementation (see issue #1430)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Re-enable NonConvexNonConvexMinkowski test
Re-enabled the test to properly debug the MinkowskiSum behavior
with coplanar faces from non-convex inputs.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Fix MinkowskiDifference hang with tolerance-based coplanarity check
- Split NonConvexNonConvexMinkowski test into separate Sum and Difference tests
- Use tolerance-based coplanarity check (1e-15) instead of exact equality
to handle floating-point precision issues from scaling operations
- Update test expected values to more precise measurements with 1e-5 tolerance
- Use ManifoldParamGuard for RAII-style parameter management in tests
The coplanarity check now uses dot product comparison instead of exact
floating-point equality (linalg::equal), which was failing for scaled
normals due to precision issues. The dot product of parallel unit vectors
should be 1.0, so we check if |dot - 1.0| < 1e-15 (near machine epsilon).

* Address PR review feedback for Minkowski implementation
- Move IsConvex() from edge_op.cpp to properties.cpp for better organization
- Fix data race in IsConvex() by using all_of instead of for_each_n with
shared anyConcave boolean (UB per pca006132's review)
- Remove unnecessary pImpl variable in IsConvex, use this directly
- Simplify convexity check to use > 0 instead of tolerance parameter
- Split NonConvexConvexMinkowski test into Sum and Difference for consistency
with NonConvexNonConvex tests
- Add analytical volume/surface area formulas for ConvexConvex tests
- Truncate excessive precision in test expected values

* Run clang-format

* Move Minkowski implementation from Manifold to Impl
- Add Impl::Minkowski method in impl.cpp with batch processing optimization
- Manifold::Minkowski now delegates to Impl::Minkowski
- This is more consistent with the codebase style and avoids repeated
GetCsgLeafNode().GetImpl() calls
- Includes BATCH_SIZE=1000 optimization for hull operations
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Add parallelization to NonConvex-NonConvex Minkowski case
- Flatten nested face pair loops into single index space
- Process pairs in parallel batches using for_each_n
- Use validHull flag array to handle coplanar face filtering
- Collect valid hulls after parallel execution for BatchBoolean
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Run clang-format
* Use periodic batch reduction for NC-NC Minkowski to handle large meshes
Replace face-pair batching with per-A-face processing and periodic
reduction every 200 faces. This approach:
- Processes A faces sequentially, creating B-face hulls in parallel
- Merges accumulated results every REDUCE_THRESHOLD faces
- Prevents memory from growing unboundedly with large meshes
Enables complex meshes like spoon (904 tris) to complete without
crashing while maintaining similar performance for smaller meshes.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Address review feedback from PR #666
- Pre-allocate composedHulls vector
- Simplify validHulls loop by checking IsEmpty() instead of separate bool vector
- Add surface area check to ConvexConvexMinkowski test
- Remove private Minkowski wrapper function, call Impl directly
- Add performance warning to MinkowskiSum/MinkowskiDifference docs
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* Increase coplanarity tolerance in NC-NC Minkowski sum
Increase kCoplanarTol from 1e-15 to 1e-9 to more reliably skip
nearly-coplanar face pairs that could cause degenerate hull
computations and potential hangs.
This tolerance is conservative enough to skip genuinely coplanar
faces while still allowing valid near-coplanar face pairs to be
processed.

* Remove extra libraries from link line
* Try to set up the manifoldConfig file to just find the required dependencies, without downloading
* Go looking for glm and Clipper2 installed with Manifold first (untested)
* Use a bundled Clipper2 copy instead of downloading
This preserves the ability to disable cross_section (and thus the use of
clipper) but replaces the Download-and-Build fetch with a bundled source
copy to avoid the network connection. If we go this route, we're also
building Clipper2 directly into Manifold so client libraries don't have
to worry about linking it in.
* Remove option and directories no longer present
* Remove option no longer present.
* Put back the default .gitignore
* Add a few more patterns
* Revert "Use a bundled Clipper2 copy instead of downloading"
Feedback is we don't want to bundle clipper, so revert inclusion

working for the tests in master branch.
* Fix conditional test, add namespace

* Rename sh directory to scripts per suggestion from pca006132
* Per pca006132, remove unnecessary find_package call for oneDPL.
* Simplify MANIFOLD_PAR to an OFF/ON setting
Per suggestion from pca006132, changed CMake logic to be ON/OFF, and
simplified the C++ defines to test for defined/undefined vs. checking
for a specific value.
* conv.h is also a private header
* Hmm - looks like flake naming was coming from MANIFOLD_PAR - try translating the settings.
* Whoops - need to translate the active value not the cached value.
* OFF is still defined, so make sure we catch that case too
* Explain multiple calls to get_filename_component
* Move parallel.h to src
* Move iters.h to src
* Place optional components in subdirectories.
