Also does reprojection automatically. 19:11:02 ... got a question from a streaming service that indicated they needed to do reprojection themselves due to increased latency. 19:11:40 ... Rik thinks we could do the reprojection internally, but we need to know when the frame was originally projected to display. 19:12:05 ... Proposal is to make the display time writable, needs some reasonable limits (can't do a year in the future) 19:12:15 ... OpenXR already supports this 19:12:19 q+ 19:12:33 scribe+ 19:12:41 scribe+ ada_ 19:12:41 OpenXR also supports requesting XR position data at any frame - does WebXR? 19:12:42 bajones: so the reprojection is an internal detail 19:12:55 ... that is based is based on the original projection time 19:13:08 ... the page thinks you present in 50ms 19:13:30 .... when you present in 55 ms, the delta will be applied to the actual pose 19:14:10 ... my question is: it seems that if the original time was xyz, the system would have to recalculate 19:14:25 .. I delivered a pose, I delivered a frame back 19:14:43 This slows down a user's input time then - is there a way to get new pose time too? 19:16:04 XR HMD POS -> Server -> WebXR 19:18:25 Could this be done by just lagging your XR app until you get a reply from the server? But that can't work because you can't get HMD / Pos - so it could be for an older XR object like that! 19:19:20 Cloud Multiplayer would totally do reproject on the server too 19:19:40 Declarative Frame Time! 19:19:44 Like CSS!!! 19:21:22 Why can not this be implemented with a Layer like this? Why is there not a WebXR Layer like Quad Layers? 19:23:15 WebXR Layer requests server rendering -> WebXR sends pos -> WebXR gets view from pos lagged in time -> WebXR Layer renders old async render 19:23:28 Async WebXR! 19:24:30 this could work for Modules in JS too! WebXR running in an iframe streaming data into the main system 19:26:49 XR Access Symposium June 15/16 https://xraccess.org/symposium/ 19:27:07 CharlesL: I will let you know about the xr access symposion in New York 19:27:27 ... they do have subsidized event tickets for non-profits and universities 19:27:45 ... I will be speaking on behalf of the social sense XR 19:28:09 ada_: there is a fund for TPAC and they are looking for funding 19:28:26 ... if your organization can help attend TPAC, please reach out and propose it 19:28:47 CharlesL: will we have a face to face at TPAC? 19:28:58 ada_: yes. We already have times 19:29:31 ... we will have overlap with apa, webapps and webgpu 19:29:40 ... and we should also have a meeting with aria 19:30:21 Awesme thanks everyone! 19:30:36 CharlesL has left #immersive-web 19:30:37 RRSAgent, make minutes 19:30:39 I have made the request to generate https://www.w3.org/2023/05/30-immersive-web-minutes.html yonet 19:32:37 RRSagent, make log public 22:35:50 CharlesL has joined #immersive-web 22:36:17 rrsagent, make logs public 22:36:23 rrsagent, draft minutes 22:36:24 I have made the request to generate https://www.w3.org/2023/05/30-immersive-web-minutes.html CharlesL 22:44:07 CharlesL has left #immersive-web 23:59:59 meeting: Immersive-Web WG/CG bi-weekly call 23:59:59 chair: Ada 23:59:59 agenda: https://github.com/immersive-web/administrivia/blob/main/meetings/wg/2023-05-30-Immersive_Web_Working_Group_Teleconference-agenda.md 23:59:59 i/XR Access Symposium June/topic: AOB/ 23:59:59 s|15/16|15/16 ->|
