0042 /// in a world so that their axial symmetry axis is in given theta and phi
0043 /// polar angles. The various ways of placement are implemented in the
0044 /// DetectorConstruction class in the following private functions:
0045 ///  - PlaceWithDirectMatrix()
0046 ///  - PlaceWithInverseMatrix()
0047 ///  - PlaceWithAxialRotations()
0048 ///  - PlaceWithEulerAngles()
0049 ///  - PlaceWithReflections()
0050 ///
0051 /// which are then called from the Construct() function.
0052 /// All method defines exactly same geometry except for the placement
0053 /// with reflection where trapezoids are placed with their symmetry axis
0054 /// in parallel with z-axis in order to make easier to check reflection
0055 /// visually.
