VRML BOF at night in Harajuku

[Jump to Japanese page]

Been to VRML (Virtual Reality Modeling Language) Bird-Of-Feather party. The main performance was Bliss that was introduced in SIGGRAPH '97. By using this, the world's first trans-pacific demonstration was done.


Date: Sat., Sep. 20, 1997 19:30~23:30 JST(+0900)

Place: Cybernet Cafe (Harajuku FACE Building OZ City 6F)

About 19:30, there was almost a hundred people on the floor of Cybernet Cafe, and they were drinking and chatting at ease. When I was about to enter the circle, I happened to meet a friend of mine. Enjoyed talking each other and ate some snacks.

20:30, David Frerichs and Shinya Matsuoka from SGI, cosponsor of this event, started the presentation about their policy for VRML. Not only the contents of the PR, but CosmoPlayer 2.0 (inner release version), the VRML browser they used attracted the audience. When they were asked "Applause if you want the Mac version (of CosmoPlayer)!" many of them (including me ;) responded.

After 21:00, the demonstration over the pacific ocean finally started. At this time, VRML data and live audio which both sampled int real time from a performer at SGI in Mt.View, California, U.S.A were going to be distributed to Tokyo. And..., detailed story will be available in other articles, so I just enjoyed the character "Bliss" jumping, dancing, and talking (in a loose high-school girl's tone ;).

data flow

dancing Bliss This was the first time ever for such a long distance data transfer and the stuff seemed to be so busy to prepare the demo. Especially the stuff at the U.S.A side had to wake up in pre-dawn time...

There were actually some sudden break of action and speech, because the data came to Japan through the SGI's intranet was transferred to ISDN line and then reached the Cafe. That could make me feel the distance in which the data came from overseas, and also reminded me of "Max Headroom." It was a little funny but "cyber"-like experience. crunched Bliss (It was also cool that I saw the head of Bliss was going to be crunched when the line between the U.S.A and Japan was cut down after the demo session. :)

After the demo finished, Mark Pesce, one of VRML frontiers, answered questions from the audience through the system. He sometimes emphasized the importance of such newly introduced technology for telling the future of VRML.

About 21:30, the attendants were enjoying VRML worlds on the workstations set in the floor after the demo and the discussion period. I left the place because the time for the last train for me was approaching.


By implementing streaming function on VRML, which will take more opportunities to be handled in a same dimension as other media.
If higher compatibility is achived, it might be possible to distribute various media in a single channel, for example, you can dynamically select video and VRML at your choice.
Interesting applications will be found if the information such as numeric values, documents, images, voices and models which can be put in streams get relations between each other and provide events happening at the place far away in a speedy and accurate way reflecting the request from the receiver (or even the sender). (So far, that could be implemented in MPEG (Moving Picture Expert Group) format media. Or QTML (QuickTime Media Layer) might do, doesn't it?)

At a technical point of view
