Hi all,

Let say I want to add a div element on a particular position overlay on top of the 3D globe. If I got a 3D coordinate on the globe, how am I project the coordinate and retrieve the 2D screen position that corresponds to the 3D coordinate in Cesium?

Or at least where can I get the world, view, projection matrix in cesium?

Thank you.

Regards,  
Dave

Dave,

See [SceneTransforms.wgs84ToWindowCoordinates](https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Source/Scene/SceneTransforms.js#L61) and perhaps [Billboard.computeScreenSpacePosition](https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Source/Scene/Billboard.js#L1007) and [Label.computeScreenSpacePosition](https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Source/Scene/Label.js#L828).
