Member Data Documentation

allowSteiner

bool mesh::GenerationOptions::allowSteiner = true

false = -YY (no Steiner points on boundary).

conformingDelaunay

bool mesh::GenerationOptions::conformingDelaunay = false

-D switch.

customSwitchString

QString mesh::GenerationOptions::customSwitchString

If non-empty, overrides everything above. Advanced.

maxArea

double mesh::GenerationOptions::maxArea = 0.0

0 = no global cap; else upper bound on triangle area. Ignored when a refinement size function is installed (see MeshGenerator::setRefineHook).

maxSteinerPoints

int mesh::GenerationOptions::maxSteinerPoints = -1

-SN cap; -1 = unlimited.

mergeTrianglePairs

bool mesh::GenerationOptions::mergeTrianglePairs = false

G2: after Triangle (and after any patches are stitched in), greedily merge adjacent triangle pairs into convex quads (mesh/meshquadmerge.h). Locked edges = every constrained segment (domain boundary, holes, breaklines, patch boundaries). Off by default (plan decision D2).

minAngle

double mesh::GenerationOptions::minAngle = 26.0

0..33 reliable; above that Triangle may not terminate. Cost rises steeply near the top of the range — 33° commonly yields 2-4x the vertices of 26° for no practical benefit.

patchSnapEps

double mesh::GenerationOptions::patchSnapEps = 0.0

G3: snap radius (map units) used to match patch vertices against the Triangle output vertices. 0 = the generator's own 1e-7 quantisation (exact match of the coordinates the PSLG was built from).

quadCleanup

QuadCleanupOptions mesh::GenerationOptions::quadCleanup

Cleanup / smoothing knobs applied to Free regions after pairing.

quadMerge

QuadMergeOptions mesh::GenerationOptions::quadMerge

quadRegionBounds

QuadQualityBounds mesh::GenerationOptions::quadRegionBounds

Acceptance bounds for quads produced inside quad regions (template and gap pairing, cleanup, smoothing). Independent of quadMerge.

quadRegionDefaultSpacing

double mesh::GenerationOptions::quadRegionDefaultSpacing = 0.0

Free-region spacing when QuadRegion::spacing == 0 and no size function is installed: side of the equilateral triangle of maxArea (sqrt(4·maxArea/sqrt 3)); when that is 0 too the region is skipped with a report line. With a size function, h = sqrt(2·targetAreaAt(centroid)).

quiet

bool mesh::GenerationOptions::quiet = true

-Q (suppress Triangle's stderr).
