Amazing light show on the face of a building. I have no idea how this was done.

Projectors with very precise keystone alignment and a LOT of lumens.

Reminds me of the Rendezvous Houston light show by some comic book artist back in the 80's. Mobius I think. That was impressive. Not the music mind you. Really bad electronica crap but the light show and fireworks were awesome. Those little keytar thingies were funny too. I think it's a French thing. I looked for video on youtube but only found grainy docu-type stuff not worth posting.

Jason ON To be fair this thing was almost entirely CGI.

Lol well they didn't film the building warping folding and collapsing and transforming itself around and things crawling through it etc

That's the projector show. That was sone with a project, regular good old fashioned lights, and the building as the backdrop/screen.

And what was the video being projected?

I'll save a step... It's a technique called 3d Projection Mapping. A company called NuFormer does a lot of them and they are the ones that made them popular in advertising. They map the building in 3d, then create a 3D replica of it digitally. Then they do all kinds of cool CGI effects to it to create a video, then they 'virtually' project the video back onto their 3D model of the building facade (to get the shadows and angles etc of the video correct as it would appear to the audience) then they output a final video which is fed to several projectors which are lined up to precisely match the building in the video.

But in the end we really don't know what was being projected: was is CGI, hand drawing, 3D modeling, etc? What we do know is this show was put on before a live crowd on the side of a building using a projector, or three, and not done on a computer with graphics overlaid on a building image.

The projection was CGI. The video you see is not editied. It's what the audience saw. Amazing stuff.

So, I asked Andrew Tamm, who filled my Stream with a hundred (sarcasm there) animated gifs and cat pictures to remove me from whatever Circle he has me in where he posts the animated gifs and cat pictures. It was either that or unfollow him and I didn't see any reason to unfollow him. Me asking https://plus.google.com/112885755521259735422/posts/78dwnvvgh4p <==edited to add the correct link Then he plusses me onto Public posts of animated cat gifs : https://plus.google.com/u/0/112885755521259735422/posts/EuuR1tnU3vJ https://plus.google.com/u/0/112885755521259735422/posts/8r6Grcm2Jpj https://plus.google.com/u/0/112885755521259735422/posts/74PgSu6iL2s Then one of his friends (or Circlers) starts plussing me into posts of animated cat gifs : https://plus.google.com/u/0/107120198886093172821/posts/gRW9JhWLs5T Don't get me wrong, I'm all about sarcasm and messing with people, but this seems sort of childish to me.

I'm shutting down Google+ for the night and quite possibly for the weekend. Why? This stupid #gifwars thing people are so proud of. This Adam Black guy said he doesn't like gifs and now everyone is mass trolling him. Having been mass trolled like this I can relate to him easily enough. Have an opinion and the collective might of Google+'s lower class denizens jump on a bandwagon. I just saw a post where someone wanted to jump on board and had to get clarification she was tagging the proper Adam Black. She wasn't even connected to him ! Nor was she a part of the original discussion. She just wanted to follow the herd. When I called her out of it she claimed, "one gif doesn't make a troll." Perhaps not, but she's contributing to a larger troll effort. One straw doesn't break the camel's back, but thousands will. So, tonight, Google+ disgusts me. It probably will tomorrow as well. And possibly Sunday. I gave up Google+ for two months this spring
