Member Function Documentation

GeodesicEngineHeat()

GeodesicEngineHeat ( Mesh & mesh )

explicit

Precompute any data required for repeated geodesic distance computation.

Parameters

mesh	Reference to the input mesh.

single_source_geodesic()

SingleSourceGeodesicResult single_source_geodesic ( const SingleSourceGeodesicOptions & options )

overridevirtual

Compute single source geodesic distances using the heat method.

This function only computes a distance, and does not compute polar angles. It is based on the following paper:

• Crane, Keenan, Clarisse Weischedel, and Max Wardetzky. "Geodesics in heat: A new approach to computing distance based on heat flow." ACM Transactions on Graphics (TOG) 32.5 (2013): 1-11.

Parameters

options

The options for the computation.

Returns

The attribute ids of the geodesic distance (id for polar angle will be invalid).

Implements GeodesicEngine< Scalar, Index >.
