Why coordinates could not be computed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NonFinite

A corner or the query point is not finite.

Degenerate

The triangle, tetrahedron or polygon is thinner than the linear tolerance: its least altitude (for a polygon, twice its area over its perimeter) is thickness.

Fields

thickness: Scalar

The shape’s thickness, in length units.

TooFewVertices

A polygon has fewer than three vertices.

Fields

count: usize

The number of vertices given.

ShortEdge

Polygon edge index, from vertex index to the next, is no longer than the linear tolerance.

Fields

index: usize

The edge’s index.

SelfIntersecting

Polygon edges first and second cross, touch or fold back onto each other within the linear tolerance, so the polygon is not simple.

Fields

first: usize

The lower edge index.

second: usize

The higher edge index.

Undefined

The mean-value weights cancel at this point, which can happen only outside a non-convex polygon: the coordinates are undefined there.

NotConvex

Wachspress and discrete harmonic coordinates require a strictly convex polygon; vertex index turns the other way.

Fields

index: usize

The reflex (or ambiguous) vertex.

VertexIndex

A face of a triangle mesh names vertex index, but the mesh has only len vertices.

Fields

face: usize

The face’s index.

index: usize

The out-of-range vertex index it named.

len: usize

The number of vertices given.
