Struct GeometryStore 

pub struct GeometryStore { /* private fields */ }

The geometry a model’s topology refers into.

Implementations

impl GeometryStore

pub const fn new() -> Self

An empty store.

pub fn add_curve(&mut self, curve: Curve) -> CurveId

Add a space curve.

pub fn add_pcurve(&mut self, curve: PlanarCurve) -> PCurveId

Add a curve in parameter space.

pub fn add_surface(&mut self, surface: SurfaceGeometry) -> SurfaceId

Add a surface.

pub fn add_triangulation(&mut self, mesh: Triangulation) -> TriangulationId

Add a cached triangulation.

pub fn curve(&self, id: CurveId) -> Option<&Curve>

The space curve behind id.

pub fn pcurve(&self, id: PCurveId) -> Option<&PlanarCurve>

The parameter-space curve behind id.

pub fn pcurve_mut(&mut self, id: PCurveId) -> Option<&mut PlanarCurve>

A pcurve, for rewriting in place: an image shifted by whole periods onto its neighbour’s branch is the same curve on the same edge.

The image must stay the edge’s curve on the surface, which leaves every face where it was: no kept face box is forgotten. What is kept of a shape’s read (crate::Model::kept_read) is forgotten.

pub fn surface(&self, id: SurfaceId) -> Option<&SurfaceGeometry>

The surface behind id.

pub fn surface_mut(&mut self, id: SurfaceId) -> Option<&mut SurfaceGeometry>

A surface, for rewriting in place: a plane or a cylinder widened to hold the trims a file puts on it is the same surface, asked over a wider window.

Every kept face box is forgotten, as any face on the surface may move, and so is what is kept of every shape’s read.

pub fn triangulation(&self, id: TriangulationId) -> Option<&Triangulation>

The cached triangulation behind id.

pub fn counts(&self) -> (usize, usize, usize)

How many curves, pcurves and surfaces are held.

pub fn holds(&self, repr: &EdgeRepr) -> bool

Whether every piece of geometry a representation names is held here.

The check a restored model needs: a handle that does not resolve is not a finding, it is a document that does not describe itself.

pub fn curves(&self) -> impl Iterator<Item = (CurveId, &Curve)>

Every space curve, with its handle, in arena order.

pub fn pcurves(&self) -> impl Iterator<Item = (PCurveId, &PlanarCurve)>

Every parameter-space curve, with its handle, in arena order.

pub fn surfaces(&self) -> impl Iterator<Item = (SurfaceId, &SurfaceGeometry)>

Every surface, with its handle, in arena order.

pub fn triangulations( &self, ) -> impl Iterator<Item = (TriangulationId, &Triangulation)>

Every cached triangulation, with its handle, in arena order.

pub fn triangulation_count(&self) -> usize

How many cached triangulations are held.
