Index	Mesh index type.

Member Data Documentation

has_overlap

template<typename Scalar, typename Index>

bool has_overlap = false

True when at least one pair of UV triangles has a positive-area interior intersection.

This is the canonical overlap indicator and is valid regardless of compute_overlap_area.

overlap_area

template<typename Scalar, typename Index>

std::optional<Scalar> overlap_area

Sum of intersection areas over all overlapping triangle pairs.

std::nullopt when UVOverlapOptions::compute_overlap_area is false or when has_overlap is false. Check has_overlap (not this field) to test for overlap existence.

overlapping_pairs

template<typename Scalar, typename Index>

std::vector<std::pair<Index, Index> > overlapping_pairs

Sorted list of (i, j) facet-index pairs (i < j) that have a positive-area interior intersection.

Empty when UVOverlapOptions::compute_overlapping_pairs is false or when there are no overlapping triangles.

overlap_coloring_id

template<typename Scalar, typename Index>

AttributeId overlap_coloring_id = invalid_attribute_id()

AttributeId of the per-facet integer coloring attribute written to the mesh.

Equals invalid_attribute_id() when UVOverlapOptions::compute_overlap_coloring is false or when there are no overlapping triangles.
