Extra information about QUMA

Hi, it is Dr. NISHIO Hirokazu. Did you already read Quma: 3D Motion-Capture Figure For 3D CG Production (Video) | TechCrunch or The Washington Post? I'm very glad to see a lot of people are interested in the project. Unfortunately, there are less information in English than in Japanese. I'll write about them.



Pronunciation
COO of 'cool' + MA of 'mama'. It is similar to the word 'KUMA'(bear) in Japanese. It is because early prototype was put in teddy-bear skin.

How much? It must be expensive!

There are no official announcement about the price. However, SoftEther said "the selling price will be between 10000 JPY and 20000 JPY" on 2009/10/30, with showing QUMA prototype. (ref. 1) In my humble opinion, it will cost much, 2 or 3 times. However it couldn't possibly imagine that it costs over 100000 JPY. Again, it is my humble opinion, not an official one.

About contributers

SoftEther said CELSYS、ViVienne, 3D-GAN and University of Tsukuba are the contributor of the project. (ref. 2)

CELSYS is selling software to make illustrations, comics and animations. It is nice if those soft supports QUMA directly. It seems possible.

ViVienne got a subsidy to a 3D-related project from MEXT(Ministry of Economy, Trade and Industry) (ref. 3). SoftEther got the subsidy form MEXT too. SoftEther colocates with Tsukuba Univ. It seems those three players are cooperating tightly.

Additionaly, the figure designer ASAI Masaki tweeted about his contribution. (ref. 4) He is very popular as a creator of figma, action figures with exchangeable faces and modules.

Modularity
SoftEther said, the joints of QUMA are modular and can be re-assemble, so you can make various animals like camels, snakes etc, not only human. In my humble opinion, no one use snakes as snakes, but tentacles. ;)

'git add -p'

Hi, it is NISHIO Hirokazu. I just found "git add -p" is very nice. I show it.

Here is a sample script. I'm going to add new function on it.

def hallo():
    print "hello!"

When I added new function 'bye', I also found there is a typo s/hallo/hello/. I fixed it too. Let me show 'git diff'

$ git diff

Now I wanted to commit it, but there are two changesets. I didn't want to commit all in one changeset. That's when I should use 'git add -p'!

Git asked me whether choose the block of changes (hunk). But it contains both changes... I chose 's' to split it.

Let me show 'git diff' again. The other modification left. Add it and commit it.

How nice is it! Does other VCS (mercurial, subversion etc.) has such feature?
