Projection Calculator

Found this online; which is good in one respect, but if you have a look it puts us at the very limit of the projectors capabitities.

There may be a way to maximise the space we have by matching the surface area to the aspect, in this case just to turn the projector on its side.

Atm i am just starting to make an absract model to show the way the method works. This is a short vid of a speaker i mapped; i was not too happy with it; but it will get better. (Believe me!)
