Detailed Description

This class holds static methods for sensor-to-mesh mapping and surface constrained distance calculation on a mesh.

This class allows sensor-to-mesh mapping and calculation of surface constrained distances. Given the positions of a row of sensors in 3D space, it finds the best fitting vertex of an underlying mesh. This can be used for later signal interpolation (see class Interpolation for more details). Given a mesh, the class can calculate shortest path on said mesh. It outputs a distance table.
