I looked around and didn’t see this bug reported anywhere. (Is there a better way to report bugs than a forum post?) Billboards get cutoff on the wrap-around edge in 2D scene mode. Here’s sandcastle code to see the problem:
var viewer = new Cesium.Viewer(‘cesiumContainer’, {
sceneMode : Cesium.SceneMode.SCENE2D
});
viewer.entities.add({
position : Cesium.Cartesian3.fromDegrees(175, 40.03883),
billboard :{
image : ‘…/images/Cesium_Logo_overlay.png’
}
});
If you switch back and forth between 2D and 3D you’ll see the billboard displays correctly in 3D but is cutoff in 2D. This is on Chrome Version 50.0.2661.102 m
