/** Helper for 3d object changes affecting 2d geometry
|
|
|
|
This class is a helper to encapsulate 3D object changes which shall
|
|
change the scene's 2D geometry. E.g. when moving one 3D object in a
|
|
scene, the visualisation would not change since the scene's 2D
|
|
attributes are defined by its 2D object transformation and the
|
|
changed content would be projected to the same 2D bounds as
|
|
before. To reflect the fact that the 2D positions may 'change' for
|
|
the user's imagination, it is necessary to calculate a new 2D
|
|
object transformation of the scene (the SnapRect) using the old 3D
|
|
transformation stack and the possibly modified 3D content and to
|
|
use it. This is only desirable if changes to the scene's content
|
|
are intended to change the scene's 2D geometry attributes
