Believe it or not, this is accomplished with one projector / one setup. The only reason you would use more then one projector is to increase the brightness (but they would be overlapping projections) or to span a large wide area. I hope that makes sense. Right now I am working with my motion graphics artists to see what we can come up with price wise.
Your absolutely right that each clients needs and equipment will be different. For instance, if a client had an indoor space that they wanted to create a show in, a projector could be selected with a matching lens to fit that room perfectly. No need to overkill it with a Barco projector. We will be working on a more detailed scale model soon. We will stay away from cartoony effects and try for more realistic effects. I think it will ultimately find its place in doors, in pre-shows or queue areas.
Outside building projections would need a higher lumen projector (expense) and are always pointed head on (on plane) with the building, which will not always be feasible for each attraction.
The second example demonstrated is clearly in the tens of thousands to produce. The 3D animation, Barco projectors, sound system, and the media servers that deliver the content. Obviously out of budget for most haunts, so we hope to come up with effects and prices that can be customized for any size budget.
Thanks R&J for your insight!
