Right-hand side of 'instanceof' is not callable

Hello,

I’m playing with geopose sample and trying to integrate some Cesium sample like this one.

So, I tried to replace the highlighted code snippet from geopose sample for…

function computeCircle(radius) {
    var positions = [];
    for (var i = 0; i < 360; i++) {
        var radians = CesiumMath.toRadians(i);
        positions.push(new Cesium.Cartesian2(radius * Math.cos(radians), radius * Math.sin(radians)));
    }
    return positions;
}

var gatechGeoEntity = new Cesium.Entity({
    name : 'Red tube with rounded corners',
    polylineVolume : {
        positions : Cartesian3.fromDegreesArray([-85.0, 32.0,
                                                        -85.0, 36.0,
                                                        -89.0, 36.0]),
        shape : computeCircle(100.0),
	orientation: Cesium.Quaternion.IDENTITY
    }
});

…and am receiving the following error in browser console:

Right-hand side of 'instanceof' is not callable, when instantiating the modified gatechGeoEntity.

Any ideas on how to proceed?

Thanks

@blairmacintyre,

We have focused on using three.js or aframe.io for content; it’s pretty trivial to show polygons or polylines.

Something like these samples?

(What do you think about a gitter channel?)

We tried it at one point; we use slack now. Go to argonjs.io, and look for the link to get an auto-invite to the ArgonJS slack.

I’ve also just created a discourse server at community.argonjs.io, to use for these kinds of discussions. I just set this up, haven’t linked it with the website yet!

Or you could post to Stack Overflow and use the argon tag, for specific coding questions.
