ProfileSection::CellCrossing Struct Reference

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...

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).
