| SbVec4d Structure |
4D vector class (double precision).
4D vector class used to store homogeneous coordinates. 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
