We should define/recommend splash images

[joshmarinacci]

There will be some interfaces that collect a group of WebVR links into a catalog like interface, meaning a group of larger images. The really is no standard for this today, but we could at least encourage people to use one of the Open Graph protocol elements, similar to what Twitter does.

Good example of an interface like this (both the menu and title cards) from Supermedium: https://www.youtube.com/watch?v=QZVSVW5_taw

This is a generic web page ask, not specific to XR, correct? This seems covered by Web App Manifests (https://www.w3.org/TR/appmanifest/), e.g. app icons and/or screenshots.

That raises a good point, though... do we want to be considering how XR plays with the display-mode option? https://www.w3.org/TR/appmanifest/#display-modes
Perhaps that's a different issue to be filed though?

yes, I totally recommend leveraging the Web-App Manifest.

there's some interesting background info. in the section about the background_color key:

The background_color member is only meant to improve the user experience while a web application is loading and MUST NOT be used by the user agent as the background color when the web application's stylesheet is available.

it's totally okay to extend the manifest format without needing the spec to change. see the Extensibility section in the spec.

so you could imagine a manifest containing a key like this one:

{
  "xr_splash_images": [
    {
      "src": "/img/splash.png",
      "type": "image/png"
    }
  ]
}

👍 yep, I still like the idea of leveraging display-mode.

I saw that you, @kearwood, and others were involved in the discussion in the CSS issue, w3c/csswg-drafts#2723. I see a PR was also merged: w3c/csswg-drafts#2719

yeah, tbh i'm a bit concerned that issue wasn't brought to the attention of this group more broadly when it was posted. We now have two different sets of values for environment blend modes that I suspect will be confusing to developers.

It seems like forward motion on this topic has stalled so I'm going to close this Issue. If someone has a plan for how to move it forward then ping me and we can re-open it.
