Detailed Description

VSG extension 3D vector class (double precision).

3D vector class used to store 3D vectors and points. Although Open Inventor fields still store only single precision values, for certain applications it is useful and convenient to be able to store and manipulate double precision values, for example, double precision coordinate data or values that will be used for further computation.
