Hey,
I’ve been trying to start working with GroundPrimitives, and this is what I see when I try to work with the example in Sandcastle.
Unless it is a bug, could it be a gpu issue? I am using Radeon HD 6450 with 512 memory, on windows 7. There are no errors in the console or WebGL reports
Cesium.GroundPrimitive.isSupported(scene)
``
returns true
This is my chrome://gpu in case that helps
