This concept was suggested by me a long time ago for blender,but now is commercial-"RATS"
A lost opportunity.

I'm guessing it doesn't work reliably when the arms are against the sides or with textured fabrics, but even so it is a big advance to not need special markers.

Really neat developments… but I doubt it will replace marker mocap systems as is.

It relies on clear silhouettes.

Notice that the model always had her arms and legs out, she never folded her arms or touched her body. also notice she's wearing very dark solid color clothing (no need to change clothing claim is inaccurate.) and she has her hair up.

This doesn't have any applications yet– except maybe capturing ballerinas.

Now when they get it to understand shading clues, and reliably make guesses of where hidden body parts are (where arms are if the subject is rolled in a ball. or where the neck is when hair is down) as we do- or understand even if the person is wearing white pants, with striped shirts- they'll have a marker mocap killer.

At that stage they wont be very far off from capturing motion (understanding what it sees as we do) from raw videos with one camera, and no special backdrops… that will be cool.

Well,

until someone finds a real dragon,unicorn, or a 12 headed p00f monster from mars, I really dont see MOCAP as much of a threat to animators.

I love the idea of nice new tools, hopefully this technology will be cheap enough that we can all enjoy and experement with it :D

However, if you are a developer and you want the feature for yourself go right ahead. ;)

To all you wonderful people who have said or are thinking this. You people end up sounding like a spoiled kid in a candy store sometimes, you know that you can talk to the developers, and you know that you'll never have to pay, so you abuse this constantly.

Before you opt for someone to create a feature for you, think please. Are you a professional, are you even any good as an artist? Do you need this feature, do you REALLY need someone to spend ages hacking together a huge feature, just so you can do absolutely nothing with it, like so many people have wasted so many of Blender's features? Will you use this in a production environment?

Seriously, think before flinch-reacting with 'U SHOULD PUT TIHS IN BLENDER AND ALSO MAKE GI KTHX'.

Although a bunch of people have already said it, I really think mocap and animators will always coexist. The team that did Advent Children talked about how they used mocap for characters walking around and speaking and subtle things, but like 90% of the action sequences wouldn't been virtually impossible to do with mocap. There've also been game studios that used mocap extensively, and ultimately realized that actions like jumping, running, and attacking simply look weak when mocapped.

Nice documentation, blendernation have full coverage of siggraph, for us blenders users, is always nice see some new technology and better, have people who want to show this advances, good work and thanks for sharing this news :D
