Detailed Description

One closed, oriented boundary loop of Curve2D segments: outer loops wind counter-clockwise, holes clockwise.

Member Function Documentation

◆ boundaryBand()

double o2::cad::surface::CurveWire::boundaryBand ( double lengthFloor ) const

inline

Half-width of the on-boundary band in parametric units: the larger of the length floor and the representation tolerance. A degenerate metric (a pole, an apex) leaves only the representation term.

Definition at line 1963 of file BoundedSurface.h.

◆ classify() [1/2]

WireClassification o2::cad::surface::CurveWire::classify	(	const Vec2 &	point,
		const ParametricMetric &	metric = `{}`
	)		const

inline

metric only sizes the on-boundary band; the winding count is topological.

Definition at line 1988 of file BoundedSurface.h.

◆ classify() [2/2]

WireClassification o2::cad::surface::CurveWire::classify	(	const Vec2 &	point,
		double	lengthFloor
	)		const

inline

Classify a point against the loop with band floor lengthFloor: Boundary within the band, else the crossing parity.

Definition at line 1966 of file BoundedSurface.h.

◆ fillBSplineCaches()

void o2::cad::surface::CurveWire::fillBSplineCaches ( ) const

inline

Fill every B-spline's polyline cache now, so that const navigation queries only read it.

Definition at line 1901 of file BoundedSurface.h.

◆ hasBSpline()

bool o2::cad::surface::CurveWire::hasBSpline ( ) const

inline

True if any curve of the loop is a B-spline (whose trimmed-face capacity is only numerically integrated, so the owning surface must report capacityIsExact() == false).

Definition at line 1925 of file BoundedSurface.h.

◆ initialize()

bool o2::cad::surface::CurveWire::initialize	(	const std::vector< Curve2D > &	inputCurves,
		WireRole	wireRole,
		WireStatus &	status,
		const ParametricMetric &	metric = `{}`,
		double	joinTolerance = `kWireJoinTolerance`
	)

inline

Build and validate the wire from an ordered closed list of curves, joining within joinTolerance through metric.

Definition at line 1845 of file BoundedSurface.h.

◆ parametricBounds()

void o2::cad::surface::CurveWire::parametricBounds	(	Vec2 &	lower,
		Vec2 &	upper
	)		const

inline

Add the loop's conservative extent, a B-spline's pole hull included, to a parametric bounding box.

Definition at line 1946 of file BoundedSurface.h.

◆ representationTolerance()

double o2::cad::surface::CurveWire::representationTolerance ( ) const

inline

The widest gap between the loop's representation and its boundary, in parametric units; 0 for lines and arcs.

Definition at line 1911 of file BoundedSurface.h.

◆ reverse()

void o2::cad::surface::CurveWire::reverse ( )

inline

Reverse the loop orientation in place (order and per-curve direction).

Definition at line 1914 of file BoundedSurface.h.

◆ sampledBoundary()

std::vector< Vec2 > o2::cad::surface::CurveWire::sampledBoundary ( int segmentsPerArc = kArcSamples ) const

inline

Ordered, closed boundary polyline; arcs are sampled into segmentsPerArc chords. This is a mesh-independent hook for visualization and tessellated fallback of curved boundaries.

Definition at line 1995 of file BoundedSurface.h.

◆ signedArea()

double o2::cad::surface::CurveWire::signedArea ( ) const

inline

Exact signed area enclosed by the loop (positive when counter-clockwise).

Definition at line 1936 of file BoundedSurface.h.

◆ storedIndexOfSource()

int o2::cad::surface::CurveWire::storedIndexOfSource ( int inputIndex ) const

inline

The stored curve that came from input curve inputIndex, or -1 if there is none.

Definition at line 1834 of file BoundedSurface.h.

◆ tightParametricBounds()

void o2::cad::surface::CurveWire::tightParametricBounds	(	Vec2 &	lower,
		Vec2 &	upper
	)		const

inline

Add the loop's extent measured on the curves to a parametric bounding box; use it to reject a wire as too big.

Definition at line 1954 of file BoundedSurface.h.
