Qtwebengine - WebGL

Development
1

I am very new to (Anki) development and for the idea I am having I need 3d plots in Anki.
I tried using the echarts-gl library, but my Anki doesn’t seem to support WebGL. However, on Windows, it seems to be supported:

Anki 2.1.26 (70784154) Python 3.8.0 Qt 5.14.1 PyQt 5.14.1
Platform: Windows 10
Flags: frz=True ao=True sv=2
Add-ons, last update check: 2020-06-13 08:48:18

Whereas on macOS:

Anki 2.1.26 (70784154) Python 3.8.0 Qt 5.13.1 PyQt 5.14.1
Platform: Mac 10.15.4

I guess it has to do with the qtwebengine. As I feel like this is unfair treatment, will macOS get a webGL-enabled qtwebengine in the future or will everyone now hate me for calling out on Windows? :stuck_out_tongue:

Also, if there are other suggestions for my problem (being able to render various 2D and 3D plots), I would appreciate them. I just need those graphs in a qt window. Numpy doesn’t seem like an easy solution to have it platform-independent.

Not something I’ve looked into I’m afraid. Maybe there are JS libs out there that can render 3d graphs without needing WebGL?

WebGL will obviously be quicker, and can get nicer results (echarts-gl can create some really, really fancy graphs - Not that I need them, but quickly rendering for 3D rotation of the graph is important to me). It would be nice if WebGL could be expected to run - or not run - on all Anki versions in the future, because otherwise developers could run into troubles if they started on one version of Anki.

With that being said, I will probably have to look into numpy anyway.

EDIT:


This example works in a browser add-on on my macOS, thus D3-3D.js is likely to work.
