Struct PlanarRegion 

pub struct PlanarRegion { /* private fields */ }
Description

A canonical straight-edged planar region with named entity sets.

Implementations§

§

impl PlanarRegion

Signature links:§PlanarRegion

pub fn new( vertices: Vec<[f64; 2]>, faces: Vec<PlanarFace>, entity_sets: Vec<NamedEntitySet>, tolerance_m: f64, ) -> Result<PlanarRegion, Diagnostic>

Signature links:newVecf642VecPlanarFaceVecNamedEntitySetf64ResultPlanarRegionDiagnostic

Canonicalize and admit one straight-edged planar region.

Vertex order, loop rotation, loop orientation, face order and entity-set order are all normalized, so two authorings of the same region are the same region. Entity-set members are already indices into the resulting canonical vertex, edge and face enumerations; they are never interpreted as author-relative indices or remapped. tolerance_m is the producer’s coherent-SI classification precision; it is part of geometry identity and is not mesh quality policy.

§Errors

Returns EQ0901 for a non-finite coordinate, an invalid tolerance, a degenerate or self-intersecting loop, coincident vertices, a hole that is not strictly inside its face, nested holes, or an entity set that is empty, unnamed, duplicated, or names an entity that does not exist.

pub fn vertices(&self) -> &[[f64; 2]]

Signature links:verticesf642

Canonical vertex coordinates in metres.

pub fn faces(&self) -> &[PlanarFace]

Signature links:facesPlanarFace

Canonical faces.

pub fn entity_sets(&self) -> &[NamedEntitySet]

Signature links:entity_setsNamedEntitySet

Canonical named entity sets.

pub fn entity_set(&self, name: &str) -> Option<&NamedEntitySet>

Signature links:entity_setstrOptionNamedEntitySet

One named entity set, if this region defines it.

pub const fn tolerance_m(&self) -> f64

Signature links:tolerance_mf64

Producer classification precision in metres.

pub fn edge_count(&self) -> usize

Signature links:edge_countusize

Total straight edges, enumerated from the canonical loops.
