WebGL

[kmbar2013]

Due to google earth api going away soon, we've decided to give Cesium (http://cesiumjs.org/) a try. However using it has been troublesome.
I created a test Qt application (Qt 5.3) to load a significant amount of data into Cesium using QWebView, as soon as the data is loaded navigation/moving the globe slows down drastically. Removing the loaded data and the globe is back to moving smoothly. Has anyone been able to load data successfully? (Using the same data with google earth, did not have these slow response times.)

I also created a test Qt application (Qt 5.4) using QWebEngineView and received the error that while my browser supports WebGL Cesium failed to initialize. Using the QWebEngineView in my app, I went to https://get.webgl.org/ and got the following: "While your browser seems to support WebGL, it is disabled or unavailable." I attempted to use 5.4 in an effort to see if the responsiveness would be affected or not but was not able to get to the point of loading data.

Any help/info would be appreciated.

If WebGL is not currently supported, are there plans for it to be supported soon?

Just an FYI, disabling network adapters (used by virtual machines) in Device Manager solved the sluggishness for me.
