I don't quite get the video..... Is it a live projection & if so did they digitaly map the buildings into a computer 1st then project the renders onto it? which makes it look amazing. There are two things i am sceptical about mind sorry & that is that the people walking about at the church don't seem to even notice the projection...... now if i was walking by i would stop, stare & point at it & some of the lighting as bright as it is doesn't reflect anywhere else in the scenery? EDIT: unless if your at the wrong angle you don't notice it?
It's "real", Mike... http://www.projectiononbuildings.com/ http://www.vimeo.com/nuformer/videos ...I think the projections are on a loop, when a company did this in Bristol that's what happened there. I guess the people had seen the animations before so didn't stop to watch again.
Yes, I think you are right. They must know exactly where the projector will be, then map things like the columns and building edges.
The ones in bristol ages ago where dont by a couple of guys from Germany, the building was mapped out by someone else and details sent over to them in Germany, they arrived a few hours before the show, made some adjustments and they where ready to go. They came to our house afterwards for a party and set up some visuals on our projector, clever guys.
