WebGL visualisations not rendering on iOS

[mattpolicastro]

I've tried opening a few WebGL-powered visualisations (e.g. wavenumbers) on iOS devices in Safari but am greeted with "Webgl is not supported by your browser - visit http://get.webgl.org for more info". However, WebGL is well-supported in Safari and is able to render graphics from other libraries (e.g. three.js).

I'm not terribly familiar with the project, but I'm poking around how GL context is determined and when showNoWebGlMsg() is fired in /src/plots/gl3d/scene.js. Am I barking up the right tree, or totally off-base?

It might be that we are passing incompatible parameters to the webgl context creation. This is hard to test without access to an iOS device. I'll see if I can scrounge one up or borrow something to test.

This is the error I'm able to trigger from Safari's developer console (iPhone 6 Plus, iOS 9.2.1):

TypeError: undefined is not an object (evaluating 'scene.glplot.canvas')              1295

Though raven.js is for Sentry, no?
Edit: happy to test anything you have from my end.

I have the same issue in both Chrome and Safari on iPhone 6 iOS 9.3. Funny thing is visiting http://get.webgl.org in the error message shows a spinning cube just fine.
Hope you can figure it out and fix so iOS users can enjoy awesome plot.ly 3D charts :)

Has there been any progress on this issue? I'd love to have a working 3D scatter plot on iOS but currently get the same message as above.

I second the request for progress on this issue. This issue is a blocker for me using 3D charts.

Same issue for Firefox running on Android (Samsung Galaxy S6)

Ok, part of the issue, at least for scatter3d, appears to be in gl-fbo ↑

Seems that iOS just does not allow rendering to floating point textures. It should be fixed here.
just mention @dfcreative

It also is a big drawback for me as I use an Ipad often for data visualisation presentations. Any updates on this?
