Detailed Description

Data structure for normalised vector in positive z-direction.

The member methods getDX() and getDY() refer to the corresponding direction cosines. Note that the direction cosines may have any value. The method getDZ() will simply return 0 if the sum of the squares of the direction cosines is larger than 1.
