Detailed Description

The MeshPoint class represents a point in the mesh data structure.

The class inherits from Vector3f and provides some additional information such as flag state and property value. The flags can be modified by the Set() and Reset() and queried by IsFlag(). A point can temporary be in an invalid state (e.g during deletion of several points), but must not be set in general, i.e. always usable within a mesh-internal algorithm.

Note: The status flag SEGMENT mark a point to be part of certain subset, a segment. This flag must not be set by any algorithm unless it adds or removes points to a segment.

Note: The status flag SELECTED mark a point to be selected which is e.g. used in the GUI. This flag must not be set by any algorithm unless it adds or removes points to the selection.
