LINETOEDGE3D Convert a 3D straight line to a 3D finite edge.

   EDGE = lineToEdge3d(LINE)
   Returns the edge with same origin as the line LINE, and with second
   extremity corresponding to the addition of line origin and direction.
   LINE is represented as [X0 Y0 Z0  DX DY DZ]
   EDGE is represented as [X1 Y1 Z1  X2 Y2 Z2]

   Example
     line = [3 4 5  1 2 3];
     edge = lineToEdge3d(line)
     edge =
          3   4   5   4   6   8
