Detailed Description

Vertex2 is a base class for all GeometricObject 's that have two vertices. It provides the derived class with methods for accessing that vertices. Further there is the possibility to give an address to a Vector3 as vertice. So if the values of these given vectors changes, the values of the vectors changes as well. To avoid segmentation faults these vector addresses must be valid as long as the Vertex2 exists.

void BALL::VIEW::Vertex2::setVertex1Address ( const Vector3 & v )

Change the vector address of the first vector. If a vector address is given the value of the first vector of this vertex2 is ignored. Instead if the method getVertex1 (or any other access method concerning the first vector) are called the value of the vector given by the vertex address is returned. The vector to which the first vertex address points must exist and be valid as long as this vertex2 exists. An object that uses this method can hook itself onto another object (speaking in terms of position). If the object changes its first position so the object derived from this vertex2 changes its first position.

Parameters:

v

Instead if the method getVertex2 (or any other access method concerning the second vector) are called the value of the vector given by the vertex address is returned. The vector to which the second vertex address points must exist and be valid as long as this vertex2 exists.
