RuntimeError: Fragment shader failed to compile

CesiumJS
1

Hello everyone.

1. A concise explanation of the problem you’re experiencing.

CesiumJS is throwing a “RuntimeError: Fragment shader failed to compile” (full trace at the end).

After searching the forums, the suggestion has been to update the graphic card’s drivers, however I’m using the latest ones.

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.

The problem occurs only if the GUI widgets are included.

If they are deactivated during initialization, the exception is not raised.

var viewer = new Cesium.Viewer(‘cesiumContainer’, {

homeButton : false,

fullscreenButton : false,

navigationHelpButton : false,

navigationInstructionsInitiallyVisible: false,

sceneModePicker: false,

selectionIndicator: false,

infoBox: false,

terrainProvider : new Cesium.CesiumTerrainProvider({

url : ‘//assets.agi.com/stk-terrain/world’

})

});

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you’re using, your operating system and browser.

Cesium version: 1.42

Browser: CEF 3.2987.1601.gf035232 (Chromium 57.0.2987.133)

Graphics card: Intel HD Graphics 520

I’m having a hard time figuring what could be going on here. Is it possible to run your application against Build/CesiumUnminified rather than Build/Cesium? It will give us a more description stack trace.

Thanks,

Hello Gabby.

I was unable to find instructions on how to use CesiumUnminified. How can I use it instead?

Thanks.

You should be able to use the Getting Started tutorial instructions and replace “/Build/Cesium/Cesium.js” with “/Build/CesiumUnminified/Cesium.js”.

You should also be able to put your code in this version of Sandcastle.

Thanks,

Gabby
