Detailed Description

Quadrilateral-cell statistics (workplans/TRI_QUAD_MESHING_PLAN §5): count, interior-angle range and bed non-planarity.

Member Data Documentation

count

int mesh::QuadStats::count = 0

Quads with valid vertex ids.

irregularVertices

int mesh::QuadStats::irregularVertices = 0

Interior vertices (not on a boundaryEdge) touched only by quads with valence != 4.

maxAngleDeg

double mesh::QuadStats::maxAngleDeg = 0.0

Largest interior corner angle.

maxAspect

double mesh::QuadStats::maxAspect = 1.0

max over quads of opposite-side-mean ratio.

maxNonPlanarity

double mesh::QuadStats::maxNonPlanarity = 0.0

Largest bed twist |z0 - z1 + z2 - z3| / 4 over the quads — the residual of the least-squares plane through the four corners; 0 for a planar bed. Project vertical units.

medianRectangularity

double mesh::QuadStats::medianRectangularity = 0.0

median of 1 - max|theta-90|/90.

minAngleDeg

double mesh::QuadStats::minAngleDeg = 360.0

Smallest interior corner angle (0 when count == 0).

minScaledJacobian

double mesh::QuadStats::minScaledJacobian = 1.0

min over quads of min_i sin(theta_i).

nonConvex

int mesh::QuadStats::nonConvex = 0

Quads failing the convexity test.

sjHistogram

int mesh::QuadStats::sjHistogram[10] = {0,0,0,0,0,0,0,0,0,0}

Histogram of scaled Jacobian in 10 bins over [0,1] (bin 9 = [0.9,1]).
