0043 /// in a world so that their axial symmetry axis is in given theta and phi
0044 /// polar angles. The various ways of placement are implemented in the
0045 /// DetectorConstruction class in the following private functions:

0047 ///  - PlaceWithInverseMatrix()
0048 ///  - PlaceWithAxialRotations()
0049 ///  - PlaceWithEulerAngles()
0050 ///  - PlaceWithReflections()
0051 ///
0052 /// which are then called from the Construct() function.
0053 /// All method defines exactly same geometry except for the placement
0054 /// with reflection where trapezoids are placed with their symmetry axis
0055 /// in parallel with z-axis in order to make easier to check reflection
0056 /// visually.
