Function Documentation

buildMeshProfile()

MeshProfile MeshProfileSampler::buildMeshProfile	(	SWMM2DMeshLayer *	mesh,
		SWMM2DResultsLayer *	results,
		const QVector< QPointF > &	scenePolyline,
		double	stepHint = 0.0
	)

Resample scenePolyline at fixed arc length and sample ground / depth / max-depth along it.

Parameters

mesh	The mesh layer (ground elevation via sampleZAt). Required.
results	The results layer (depth + envelope). May be null — then only ground is populated and hasResults is false.
scenePolyline	Traced vertices in scene coords (sx = mapX, sy = -mapY).
stepHint	Optional fixed arc-length step (scene units). When ≤ 0 a characteristic cell size is derived from the mesh extent.

kMaxSamples

constexpr int MeshProfileSampler::kMaxSamples = ProfileSection::kMaxSamples

inlineconstexpr

Hard cap on sample count so a very long polyline can't blow up the per-frame resample / per-cell envelope work.
