Using Mirrors in a design
It is possible to use mirrors in projection theatre designs in nControl.
Whenever you want to use a mirror in your design, you should first model the theatre as if there was no mirror.
Place the projector with no regard to obstacles or walls in such a way that the projector fills the area of the screen you want it to fill.
Then you add the mirror.
You can now adjust mirror angle and mirror distance to projector in order to get the projector to the position you want it to be.
NOTE: when using mirrors nControl operates with both projectors and "projectors in virtual position".
By right-clicking in the 3D view and selecting properties, you can choose if you want to see projectors or "projectors in virtual position" or both.
