Detailed Description

Class that represents pre-transformed axes samples for 3D volumes.

This class generates an array of 3D coordinate vectors for each of the three coordinate axes X, Y, and Z. These arrays contain direction vectors that directly point to the coordinate of every sample on the respective axis. These vectors are computed with respect to the object's coordinate transformation as well as a second Volume's transformation and coordinate offset. The Z-axis array contains this Volume's coordinate offset as defined by the transformation translation component as well. The vectors from the arrays can therefore directly be used for probing the other Volume using the ProbeNoXform member function.
