Moving a Model

I'm really new to all this so I'm sorry if this is a stupid question but...

How would I use the ScreenSpaceEventHandler to move a model around the screen with the mouse? Should I even be using ScreenSpaceEventHandler? I saw that MouseEventType was switched to that and MouseAction was switched to InputAction.
So if I were to implement this in 3D models, how would I make the model move around the screen with my mouse?


See the picking example for how to get the world position under the mouse. Then see the 3D model example for how to move the model to that position. In particular, you want this line:

var modelMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(ellipsoid.cartographicToCartesian(Cesium.Cartographic.fromDegrees(-123.0744619, 44.0503706, height)));

which will be a bit more concise when b29 is released on June 2:

var modelMatrix = Cesium.Transforms.eastNorthUpToFixedFrame(Cartesian3.fromDegrees(-123.0744619, 44.0503706, height));


Thanks!! I don't have it perfect but it will be fine for what I need. I appreciate the help!
