| see methods' descriptions in IFastWindingNumber | |
| Expected< void > | calcSelfIntersections (FaceBitSet &res, float beta, const ProgressCallback &cb) override |
| calculates winding numbers for all centers of mesh's triangles. if winding number is less than 0 or greater then 1, that face is marked as self-intersected | |
| Expected< void > | calcFromGrid (std::vector< float > &res, const Vector3i &dims, const AffineXf3f &gridToMeshXf, float beta, const ProgressCallback &cb) override |
| calculates winding numbers in each point from a three-dimensional grid | |

| Expected< void > | calcFromGridWithDistances (std::vector< float > &res, const Vector3i &dims, const AffineXf3f &gridToMeshXf, const DistanceToMeshOptions &options, const ProgressCallback &cb) override |
| calculates distances with the sign obtained from generalized winding number in each point from a three-dimensional grid; if sqr(res) < minDistSq or sqr(res) >= maxDistSq, then NaN is returned for such point | |

| virtual | ~IFastWindingNumber ()=default |
the class for fast approximate computation of winding number for a mesh (using its AABB tree)
Note, this used to be [[nodiscard]], but GCC 12 doesn't understand both [[...]] and __attribute__(...) on the same class. A possible fix is to change MRMESH_CLASS globally to [[__gnu__::__visibility__("default")]].
