Detailed Description

MeshViz Class to build a set of axes on a parallelepiped relating to the view.

This class builds a set of 3D axes displayed on some of the 12 edges of a parallelepiped. The choice of the edges depends on the view defined by the current camera (see SoCamera class). The graduations and the title of the axes are always legible whatever the view definition. The two points (start and end fields) define the diagonal of the parallelepiped and only the edges which are intersecting a visible face and an invisible face will be graduated. The visible and invisible faces depend on the view definition. The visible faces of the parallelepiped are the back faces.

       Face 1 : 2 3 4 5 ==> edges : (2,3) (3,4) (4,5) (5,2)
       Face 2 : 0 1 2 3 ==> edges : (0,1) (1,2) (2,3) (3,0)
       Face 3 : 0 1 6 7 ==> edges : (0,1) (1,6) (6,7) (7,0)
       Face 4 : 0 3 4 7 ==> edges : (0,3) (3,4) (4,7) (7,0)
       Face 5 : 1 2 5 6 ==> edges : (1,2) (2,5) (5,6) (6,1)
   

The graduations of these axes are defined by the fields gradStart and gradEnd. However if these fields are equal, the fields start and end are used to define the graduation values. Furthermore, the fields gradStart and gradEnd are always ignored for axis type GENERALIZED.
