Edge/poor video card/Mobil Support

Open gchoqueux opened this issue 8 years ago • 8 comments

iTowns must support maximum devices and navigator. Some WebGL extensions is not supported :

  • float texture (use in elevation)
  • log depth

WebGL 2.0 is now supported on mobile and Edge. As webgl 2.0 is also supported by itowns, Float texture and log depth are no longer a issue for these platforms.

Please be more specific with the intended target :

  • we will definitely not support all version of IE
  • some versions do not even have webgl
  • the situation is quickly evolving with Edge replacing IE ( and other browsers rising)

Reminder of Web browsers shares :

  • IE 11 : 6%
  • IE 9 : 2%

It would be interesting to have statistics from Geoportail over the last 3 months to be able to focus on the important things.

One option would be to have a very degraded mode for IE compatibility.

Only IE11 continues to be supported by Microsoft (announced on January this year), and is the only one to natively support WebGL anyway. This is WebGL 0.94 though, when all other browsers support WebGL 1.

Only IE11, I think IE11 support will open the support of certain cards and mobile

@LoicUTC @PhilippeMarc-IGN, what web browsers, in which versions and what platforms do we aim to support with itowns? Depending on this answer, we can close this issue or not.

Currently, itowns is known to be supported on last versions Chrome, Firefox, Safari and on these browsers for mobile. Others needs to be tested.

Browser market share :

  • Chrome 65 %
  • Safari 19 %
  • Edge 4 %
  • Firefox 3 %

Edge is now Chromium based, I think it could be added. For geoportail we support the last year versions, it seems to be a good option.

We validated in proposal/issue #2256 that we now only support the defaults browserlist target with mandatory support of WebGL 2.0.

This was implemented in itowns in PR #2252.

@jailln We can now close this issue.
