Help me identify this location/event in China?

July 26, 2019 7:57 AM

I was watching a documentary (The New Silk Road, From Kyrgyzstan to Duisburg, from DW) and I would like to find out more about the lighting display shown at 41:37 in this youtube clip. I am assuming this is some kind of projection display but I'd like to find out more details. Can you help me narrow down the location and/or the particular event or initiative this was for? Thanks!

Yes it's projection. The term you are looking for is projection mapping. Very related to what you see on a court or ice before NBA or NHL games. Companies like christie digital make the processors and projectors.

Essentially the processor smooths out irregularities of the surface being 3 dimensional so you can see a cohesive image. The gaps are often referred to as air gap or mulliol removal (even though window millions are tiny and these gaps are building sized).

It's a lot of stuff. Each projected image is a stack of projectors mirroring each other to get the net brightness higher. Lots of payout servers making the image and then the above mentioned processors mapping those play out sources onto the surfaces.

Wow. I was so focused on the technical part I completely missed the spirit of the question. Sorry.
