scdcInterpolationMat()

QSharedPointer< SparseMatrix< float > > GeometryInfo::scdcInterpolationMat ( const Eigen::MatrixX3f & matVertices, const std::vector< Eigen::VectorXi > & vecNeighborVertices, const Eigen::VectorXi & vecVertSubset, double(* interpolationFunction )(double), double dCancelDist, std::function< void(int, int)> progressCallback = nullptr )

static

scdcInterpolationMat Computes geodesic distances (SCDC) and builds the sparse interpolation matrix in a single pass, without allocating a dense nVertices x nSources distance table. Produces identical results to scdc() + Interpolation::createInterpolationMat() but uses dramatically less memory (sparse representation only stores entries within cancelDist).

Parameters

[in]	matVertices	Vertex positions (nVertices x 3).
[in]	vecNeighborVertices	Adjacency list for each vertex.
[in]	vecVertSubset	Source vertex indices.
[in]	interpolationFunction	Weight function (e.g. Interpolation::cubic).
[in]	dCancelDist	Maximum geodesic distance for interpolation.
[in]	progressCallback	Optional callback reporting Dijkstra progress (current, total).

Returns

Sparse interpolation matrix (nVertices x nSources).
