edges present on only one face (e.g. a missing face)

appearing once: a face is missing on the other side

Definition at line 4712 of file BoundedSurface.h.

◆ edgeDegenerateCount

int o2::cad::surface::ClosureReport::edgeDegenerateCount = 0

flagged degenerate (cone apex, sphere pole): excluded from the counts above, because a point has no second face to meet

int o2::cad::surface::ClosureReport::edgeSharedCount = 0

appearing exactly twice, opposite sense: a properly shared edge

Definition at line 4711 of file BoundedSurface.h.

◆ matchedRims

int o2::cad::surface::ClosureReport::matchedRims = 0

every chord has another face within the match band, traversed the opposite way

Definition at line 4695 of file BoundedSurface.h.

◆ maxRimIsolation

double o2::cad::surface::ClosureReport::maxRimIsolation = 0.

Definition at line 4687 of file BoundedSurface.h.

◆ maxSharedEdgeDeviation

double o2::cad::surface::ClosureReport::maxSharedEdgeDeviation = 0.

Largest Hausdorff distance between two faces' realisations of a shared edge, in cm; a measurement, not a verdict.

Definition at line 4719 of file BoundedSurface.h.

uint32_t o2::cad::surface::ClosureReport::maxSharedEdgeDeviationEdge = 0

which edge that was

Definition at line 4720 of file BoundedSurface.h.

◆ maxSharedEdgeDeviationFaces

int o2::cad::surface::ClosureReport::maxSharedEdgeDeviationFaces[2] = {-1, -1}

between which two faces

Definition at line 4722 of file BoundedSurface.h.

◆ maxSharedEdgeDeviationPoint

Vec3 o2::cad::surface::ClosureReport::maxSharedEdgeDeviationPoint {}

and where on it

Definition at line 4721 of file BoundedSurface.h.

◆ nonManifoldEdges

int o2::cad::surface::ClosureReport::nonManifoldEdges = 0

edges shared by more than two faces

Definition at line 4680 of file BoundedSurface.h.

◆ nonManifoldRims

int o2::cad::surface::ClosureReport::nonManifoldRims = 0

some chord has two or more other faces within rimEpsilon

Definition at line 4699 of file BoundedSurface.h.

◆ orientationConsistent

bool o2::cad::surface::ClosureReport::orientationConsistent = true

shared edges are traversed in opposite directions

Definition at line 4678 of file BoundedSurface.h.

◆ reversedEdges

int o2::cad::surface::ClosureReport::reversedEdges = 0

edges shared by two faces in the same direction

Definition at line 4681 of file BoundedSurface.h.

◆ reversedRims

int o2::cad::surface::ClosureReport::reversedRims = 0

matched, but the partner traverses the shared curve the same way (one face's outward normal points inward)

Definition at line 4697 of file BoundedSurface.h.

◆ rimChordResolution

double o2::cad::surface::ClosureReport::rimChordResolution = 0.

the largest amount by which any rim polyline can sit off the smooth rim it samples, in cm; the per-chord value of this is what widens the match band

Definition at line 4691 of file BoundedSurface.h.

◆ rimEpsilon

double o2::cad::surface::ClosureReport::rimEpsilon = 0.

the declared matching tolerance, in cm

Definition at line 4690 of file BoundedSurface.h.

◆ rimRecords

std::vector<RimRecord> o2::cad::surface::ClosureReport::rimRecords

One entry per rim, in the order the faces were visited: the detail behind the counters above. The counters say how many rims are open; these say which, and where.

Definition at line 4703 of file BoundedSurface.h.

◆ rims

int o2::cad::surface::ClosureReport::rims = 0

total number of trim loops over all faces

Definition at line 4694 of file BoundedSurface.h.

shared edges both of whose faces could be sampled

Definition at line 4723 of file BoundedSurface.h.

◆ sharedEdgesUnmeasured

int o2::cad::surface::ClosureReport::sharedEdgesUnmeasured = 0

the rest: a parametric-rectangle face names its edges but carries no curve for them, so there is nothing to compare

Definition at line 4724 of file BoundedSurface.h.

◆ signedVolume

double o2::cad::surface::ClosureReport::signedVolume = 0.

divergence-theorem volume; positive if normals point out

Definition at line 4682 of file BoundedSurface.h.

double o2::cad::surface::ClosureReport::totalRimLength = 0.

summed length in cm of every face's trim boundary

Definition at line 4688 of file BoundedSurface.h.

◆ unmatchedRimLength

double o2::cad::surface::ClosureReport::unmatchedRimLength = 0.

how much of it has no other face within the match band, cm
