Simulation
See what a mapping looks like.
A house and a cube at night, lit by one projector running BeamerMap. Step through the scenes, switch the projector off to compare, or shake the projector and drag the corners back into place yourself.

Surfaces follow the object
The facade and each cube face are separate surfaces. Their four corners sit exactly on the real corners, so the picture is warped in perspective to match.
Masks keep windows dark
Windows and the door are masked, so no light shines into the house. Switch the projector off to see the bare building.
Scenes with crossfades
Every scene is a different look. The show advances on its own and fades between them; pause it any time, just like the Play show button in BeamerMap.
