Compute geodesic distance from a set of seed vertices.

The methods works by a Dykstra-like breadth first traversal from the seed vertices, implemented by a head structure. See [9] for details.

SurfaceGeodesic | ( | SurfaceMesh & | mesh, |

bool | use_virtual_edges = `true` |

) |

Construct with mesh.

Computes virtual edges only (if set to true). Call compute() to compute geodesic distances.

unsigned int compute | ( | const std::vector< Vertex > & | seed, |

Scalar | maxdist = `FLT_MAX` , |

) |

Compute geodesic distances from specified seed points up to the specified maximum distance and up to a maximum number of neighbors.

returns how many neighbors have been found
