RectanglePrimitive has been deprecated

[gezonthenet]

As of Cesium 1.17 RectanglePrimitve has been deprecated so this will need to be updated as the Extent primitive can no longer be drawn.

@getardretard did you manage to figure out a way of solving this?

I am no expert but I updated this section:

if (extent == null) { 
                //extent = new Cesium.RectanglePrimitive();
                //extent.asynchronous = false;
                //primitives.add(extent);
                extent = new Cesium.Primitive({
                        geometryInstances :  new Cesium.RectangleGeometry()
                        //appearance : new Cesium.EllipsoidSurfaceAppearance({
                        //      material : Cesium.Material.fromType('Checkerboard')
                        //})
                });
                extent.asynchronous = false;
                primitives.add(extent);
}
extent.geometryInstances.rectangle = value;

But I cannot get the rectangle to be yellow when it is first drawn. When I add the appearance option (just to test) I get an error saying there is an undefined Worker.

I just changed extent = new Cesium.RectanglePrimitive(); to extent = new Cesium.Primitive();

Hi @getardretard, I am using following but still not getting rectangle while drawing.. did you get any solution for this.

if(extent == null) { var rectangleInstance = new Cesium.GeometryInstance({ geometry : new Cesium.RectangleGeometry({ rectangle : value, vertexFormat : Cesium.PerInstanceColorAppearance.VERTEX_FORMAT }), attributes : { color : new Cesium.ColorGeometryInstanceAttribute(0.0, 1.0, 1.0, 0.5) } });

            extent = new Cesium.Primitive({
              geometryInstances : rectangleInstance,
              appearance : new Cesium.PerInstanceColorAppearance(),
              releaseGeometryInstances: false
            });
            //extent.material = options.material;
            extent.asynchronous = false;
            primitives.add(extent);
        }
        extent.geometryInstances.geometry._rectangle = value;

Thanks

Hi @raghuburgala, I still use the code I posted above. I haven't seen any update to this. It seems to do the job for me. Cheers.

Hi @getardretard, I resolved my issue by using following code.

if(extent == null) { extent = new DrawHelper.ExtentPrimitive({ extent : value, material : options.material, }); extent.asynchronous = false; primitives.add(extent); } extent.setExtent(value);

Thanks.

cesium version 1.24 can't find the api of RectanglePrimitive or ExtentPrimitive. replace it GroundPrimitive,and i find it works！ http://cesiumjs.org/Cesium/Build/Documentation/GroundPrimitive.html?classFilter=GroundPrimitive

Thanks.
