1. A concise explanation of the problem you’re experiencing.
GroundPolylineGeometry are broken on mobile (graphical glitch on Galaxy Note 9, Huawei P9 Lite, Wikio UFeel; on a old Note 3 polyline is drawn under the terrain)
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
Just try the Sandcastle demo.
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
Because we made a nice Cesium based widget to show cycle routes and we were very happy,
and now we discovered that it doesn’t work on mobile and we are soo sad
(I’m joking, for our use case I think we can easily switch to corridors - we show just one route at a time - but I think that it simply should works on every device)
4. The Cesium version you’re using, your operating system and browser.
I forgot to specify that you can see the glitch only a certain distances (near - but not so near, a “useful” near, not a “I wanna see the bee on the flower” near, and far).
Hi Omar,
thank to you for your reply.
I have replicated the problem with the Sandcastle example that Gary linked on his article (https://cesium.com/blog/2018/07/23/polylines-on-terrain/),
I tried now the Sandcastle example you linked and I think that the problem is a lot bigger than previously thought. My results: Galaxy Note 9
