void WGridRegular3DTest::testGetVoxelNumberOfGeneralPosition ( void  )
inline

The cell number of a Position is defined as follows:

 y-axis
   |_____ _____ ___   _
 3 |     |     |       |
   |     |     | ...   + dy
   |_____|_____|___   _|
 2 |     | . Line
   |     |/    | ...
   |_____/___ _|___
 1 |    /|     |
   |   ' |     | ...
   |_____|_____|______ x-axis
  /0     1     2
 / `--.--ยด
/    dx
origin e.g. ( 3.1, 3.2, -6 ) and dx == dy == 1.0 ( the z-axis is ignored in this example )

Hence the line starts at approx. ( 3.85, 3.7, -6 ) and ends at approx. ( 4.35, 5.0 , -6 ). The Cell number e.g. of the start point is then: 4 and of the end point: 7.
