Polygons, polylines, billboards, and labels clamped to terrain in Cesium 1.7?

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

Hi Giovanni,

This feature did not make 1.7 but is currently being worked in the ground-primitive and globe-depth branches.
