The latency is way more impressive than the fps Edit: the video gets the point across more effectively IMO: https://youtu.be/-bh1MHuA5jU

Well you can't really achieve low latency if the end-to-end system has low FPS.

Yes but you can achieve high fps very easily if you have a day to compute each frame! :)

Disney has a (poor) version of this idea. They project an animation onto wedding cakes at their resorts. They're pre-rendered though, rather than dynamic like this. It'd be fascinating to see what uses they could come up with for this stuff.

Disney does a lot of projection mapping in the parks right now, but it's all (AFAIK) the traditional, pre-rendered type, with animations projected onto large static surfaces like the Magic Kingdom's castle, or onto animatronics with pre-planned motion paths. I'm having a little trouble visualizing how this non-rigid projection mapping could get applied in a practical way in the parks today, mostly because it seems li…

Augmenting human actors/customers (think Harry Potter spells) could get interesting.

The second generation of the projection tech does color: http://www.k2.t.u-tokyo.ac.jp/vision/dynaflashv2/index-e.htm... And they can now do the tracking without the infrared paint: http://www.k2.t.u-tokyo.ac.jp/vision/MIDAS/index-e.html

I cant describe how awesome this is to me, personally.

In 1998 I was hired on a contract to do a Fashion Show, where I developed graffix to project onto models who were on the catwalk in this theater....

Basically it was a music + visuals show where the models would walk down the catwalk and present themselves....

Guess what tool I had available to me to make this happen...

FUCKING POWERPOINT

I F5'd that bitch and projected a slide per model on a projector borrowed from work with me manually changing slides with --> for each model....

> Disney has a (poor) version Seems an unnecessarily nasty way to refer to what I guess is earlier less advanced work.

What exactly is "nasty" about it, and why would anyone take offense at the use of the term "poor version"?

What do you think the word 'poor' means when referring to quality? Might be kinder to say 'less advanced' or 'simpler' or 'earlier'.

I was fortunate to see some of the 2019 projection mapping competition on odawara castle. It is absolutely mind bending technology. This is the real beginning of augmented reality, not VR or cell phones

One downside with this approach is that you need something to bounce the light off of (e.g., a surface), so adding virtual objects to AR is difficult if the objects aren't positioned at the surface of real world objects. That's an effect you often want to achieve in AR applications.

Nah if you see it in person you understand. No matter the surface, you can create a virtual 3d space from the perspective of the observer.

This gives you an idea but in person the illusion is stronger.
