/// in a world so that their axial symmetry axis is in given theta and phi
|
|
/// polar angles. The various ways of placement are implemented in the

|
/// DetectorConstruction class in the following private functions:

|
/// - PlaceWithDirectMatrix()
|
|
/// - PlaceWithInverseMatrix()
|
|
/// - PlaceWithAxialRotations()
|
|
/// - PlaceWithEulerAngles()
|
|
/// - PlaceWithReflections()
|
|
///
|
|
/// which are then called from the Construct() function.
|
|
/// All method defines exactly same geometry except for the placement
|
|
/// with reflection where trapezoids are placed with their symmetry axis
|
|
/// in parallel with z-axis in order to make easier to check reflection
|

/// visually.
