Hi,
within the “Cesium in 2015 - Kickoff” thread [1] Patrick said on its reply on the 21st of January that Polygons, polylines, billboards, and labels clamped to terrain would have been available with Cesium 1.7. I can’t see this mentioned in the blog post nor in the changelog.
Is it there or was it procrastinated to a future release?
Cheers,
Giovanni
