Detailed Description

Parameters for the normal-deviation terrain thinning.

Member Data Documentation

gridSpacing

double mesh::DTMThinnerOptions::gridSpacing = 0.0

Sampling step in map units. 0 = native pixel size.

maxIterations

int mesh::DTMThinnerOptions::maxIterations = 0

Number of thinning passes. 0 = unlimited (convergence).

maxPoints

int mesh::DTMThinnerOptions::maxPoints = 0

Stop thinning once the active count falls to this or below. Checked BETWEEN passes, so the result may undershoot; it is not a hard cap. 0 = unlimited.

minSpacing

double mesh::DTMThinnerOptions::minSpacing = 0.0

Min inter-point distance, map units. 0 = auto (2×pixelSize).

normalDotThreshold

double mesh::DTMThinnerOptions::normalDotThreshold = 0.95

Remove vertex when score >= this (smooth surface). score = min (or avg) dot(vertex_normal, face_normal). [0, 1]. 0.95 ≈ 18°; 0.0 = remove everything flat.

useAverageDot

bool mesh::DTMThinnerOptions::useAverageDot = false

true = use average dot product; false = minimum.

useMinSpacing

bool mesh::DTMThinnerOptions::useMinSpacing = false

Enable Poisson-disk minimum-spacing filter.
