Classes
struct	ProfileSection::Sample
	One point along the traced cross-section. More...
struct	ProfileSection::CellCrossing
	A point where the traced line crosses a mesh-cell (triangle) edge. Plotted as a dot on the ground line so the per-cell interpolation basis (constant-per-cell depth → stepped WSE) is visible: each dot marks a cell boundary; the span between two dots is one cell. Unused by raster sections (a DEM has no cells to cross). More...
struct	ProfileSection::Section
	The assembled cross-section: ordered samples + a results flag. More...

Namespaces

Originally the MeshProfileSampler::MeshProfile struct; extracted here so the DEM-raster sampler (RasterProfileSampler) can feed the same MeshProfilePlotWidget chart. MeshProfileSampler's names are aliases of these, so every existing mesh call site is untouched.

A raster (ground-only) section leaves depthNow / maxDepth at 0, triIdx at -1, crossings empty and hasResults false — the chart's water passes are already gated on hasResults, so it renders ground + soil fill only.
