Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

corners_in: usize

Corners passed in.

corners_used: usize

Corners that survived the axis-validity pre-filter.

triangles: usize

Triangles produced by Delaunay triangulation.

grid_edges: usize

Half-edges classified as Grid (counted twice, once per direction).

diagonal_edges: usize

Half-edges classified as Diagonal.

spurious_edges: usize

Half-edges classified as Spurious.

triangles_mergeable: usize

Triangles with exactly one Diagonal edge and two Grid edges (i.e. eligible to merge into a quad if their buddy agrees).

triangles_all_grid: usize

Triangles with all three edges classified as Grid (suggests the triangle spans more than one cell — the paper’s failure mode at very low view angles).

triangles_multi_diag: usize

Triangles with multiple Diagonal edges (ambiguous).

triangles_has_spurious: usize

Triangles with at least one Spurious edge.

quads_merged: usize

Triangle pairs merged into quads.

quads_kept: usize

Quads surviving topological + geometric filtering.

components: usize

Connected quad-mesh components after walking.
