Speed and performance were great without a single crash.
Admittedly this was only at 1024 x 768 resolution but it was a lot more responsive than V3
We built up sections of the projection surface through out the event and changed the mask accordingly.
Each section corresponded to what was happening on stage.
When the surface was complete we projected a video clip over it of a collage of photos taken of the people attending the event which zoomed out to display a picture.
All masks and some of the content were set up before the rig from a CAD drawing of the surface.
