Box entity distorted in ios

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

I drew a box in Sandcastle, but the output looks twisted in ios safari.

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

var viewer = new Cesium.Viewer(‘cesiumContainer’);

var redBox = viewer.entities.add({

name : 'Red box with black outline',

position: Cesium.Cartesian3.fromDegrees(-107.0, 40.0, 0.0),

box : {

    dimensions : new Cesium.Cartesian3(0.2,0.2,1),

    material : Cesium.Color.RED,

    outline : true,

    outlineColor : Cesium.Color.BLACK





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

Cesium 1.49

ios 11

Safari browser

Any help is appreciated.



That is a little bizarre. I’m not sure why off the top of my head it would be distorted like that. I opened a GitHub issue to track this:

Feel free to follow the discussion there. I’ll post back here once it’s been resolved.
