10:24:42 DL: I don't think so 10:25:09 CC: In our case we are just extending vector graphics with 3D depth information 10:25:25 GK: So are you trying to solve both problems? 10:25:36 DL: We're first focusing on video/images 10:25:55 jalvinen has joined #3dweb 10:26:03 stefanh has joined #3dweb 10:27:21 Present: Dong-Young_Lee, Cheng_Gu, Jens_Bachmann, Yoshiharu_Dema, George_Kakatsakis, Giles_Godam-Brown, Michael_Champion, Stefan_Hahansson, Cyril_Concolato, Jari_Alvinen, Sangwhan_Moon, Ryoichi_Kawada 10:27:42 s/The specification defines/The proposal defines/ 10:28:47 jens has joined #3dweb 10:29:16 DL: When implementing, the image decoder might be able to detect if the image is stereoscopic or not 10:29:23 … of course this is just a possibility 10:29:51 RRSAgent, pointer 10:29:51 See http://www.w3.org/2012/10/31-3dweb-irc#T10-29-51 10:30:06 RRSAgent, make logs public 10:30:33 rrsagent, draft minutes 10:30:33 I have made the request to generate http://www.w3.org/2012/10/31-3dweb-minutes.html kaz 10:31:12 … for HTML content, web content consists of multiple block elements 10:31:47 tpacbot has joined #3dweb 10:31:47 … so you can place the depth of the content using this mechanism 10:32:43 GK: Currently the content is flat, and there is no depth - so what would you have to do to give a z-index? 10:33:14 … z-index being depth of the block element in this case 10:33:46 DL: A cover flow like example could be one possibility to explain this 10:34:10 GK: Would it be a usecase for GUI elements to be steroscopic? 10:35:53 GG: That could be quite disastrous 10:36:00 DL: I agree 10:36:06 rrsagent, draft minutes 10:36:06 I have made the request to generate http://www.w3.org/2012/10/31-3dweb-minutes.html sangwhan 10:36:39 chong has joined #3dweb 10:37:21 GG: We also have to think about subtitles 10:37:51 … there has been prior work regarding this, about placement of objects within 3D video 10:38:41 SH: If you have content in 2D and 3D, would the device be aware of how to display it? 10:39:02 DL: No work has been done, but it should 10:39:23 GK: There was a issue with HDMI overlooking this, so this should be addressed 10:40:06 DL: If there is a 3D image embedded in web content, the authors should also consider graceful degradation 10:40:18 … which is a similar issue to responsive images 10:40:41 … so in case the user agent is not capable of 3D it should display 2D 10:42:29 kawada has joined #3dweb 10:43:13 DL explaining diagram http://www.w3.org/TR/css3-transforms/perspective_origin.png in a stereoscopic context 10:44:33 DL: We can modify the existing implementation inside user agents to draw for both the left and right eye separately, so it probably is not that complicated 10:44:52 SH: Is there any official group work being done on this? 10:45:11 DL: I proposed it in Web and TV, but nothing official as for now 10:45:26 … there is a possibility of setting up a small WG for this 10:45:44 RK: We had discussions about setting up a TF for this 10:45:47 DL: Yes 10:46:29 Chair: Dong-Young_Lee 10:46:44 GK: We should probably look at what the gaming companies have already done 10:47:24 rrsagent, draft minutes 10:47:24 I have made the request to generate http://www.w3.org/2012/10/31-3dweb-minutes.html sangwhan 10:49:53 pal has joined #3dweb 10:50:02 pal = Pierre Lemieux 10:50:16 PL: If you describe a object in 3D, how would you define where the base of zero disparity is? 10:50:17 Dewa has joined #3dweb 10:50:22 DL: That would be the screen 10:50:38 JonathanJ2 has joined #3dweb 10:51:15 Meeting: Stereoscope/3D Web 10:51:21 PL: if zero disparity corresponds to CSS3 coordinate z = 0, it should be explicitly specified 10:51:41 PL: video content is authored with zero disparity corresponding to the screen 10:52:04 rrsagent, draft minutes 10:52:04 I have made the request to generate http://www.w3.org/2012/10/31-3dweb-minutes.html sangwhan 10:53:12 RRSAgent, make log public 10:54:59 JB: I don't think this enough to cover all the usecases 10:56:34 … if you want something that true 3D for HTML content, just using CSS 3D transforms might not be enough and you should talk with the HTML WG 10:58:20 rrsagent, make minutes 10:58:20 I have made the request to generate http://www.w3.org/2012/10/31-3dweb-minutes.html sangwhan 10:58:34 rrsagent, bye 10:58:34 I see no action items
