<ada_> Hi, I just rememebered the URL changed to the zoom one and the meeting template has the old URL
Allow adjustment of display time https://github.com/immersive-web/webxr/issues/1328
rik: WebXR gives display time, which is when it thinks the frame will be displayed. Also does reprojection automatically.
… got a question from a streaming service that indicated they needed to do reprojection themselves due to increased latency.
… Rik thinks we could do the reprojection internally, but we need to know when the frame was originally projected to display.
… Proposal is to make the display time writable, needs some reasonable limits (can't do a year in the future)
… OpenXR already supports this
<Koolala> OpenXR also supports requesting XR position data at any frame - does WebXR?
bajones: so the reprojection is an internal detail
… that is based is based on the original projection time
… the page thinks you present in 50ms
… when you present in 55 ms, the delta will be applied to the actual pose
… my question is: it seems that if the original time was xyz, the system would have to recalculate
… I delivered a pose, I delivered a frame back
<Koolala> This slows down a user's input time then - is there a way to get new pose time too?
<Koolala> XR HMD POS -> Server -> WebXR
<Koolala> 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!
<Koolala> Cloud Multiplayer would totally do reproject on the server too
<Koolala> Declarative Frame Time!
<Koolala> Like CSS!!!
<Koolala> Why can not this be implemented with a Layer like this? Why is there not a WebXR Layer like Quad Layers?
<Koolala> WebXR Layer requests server rendering -> WebXR sends pos -> WebXR gets view from pos lagged in time -> WebXR Layer renders old async render
<Koolala> Async WebXR!
<Koolala> this could work for Modules in JS too! WebXR running in an iframe streaming data into the main system

… if your organization can help attend TPAC, please reach out and propose it
CharlesL: will we have a face to face at TPAC?
ada_: yes. We already have times
… we will have overlap with apa, webapps and webgpu
… and we should also have a meeting with aria
<Koolala> Awesme thanks everyone!
