Any updates on polylines over terrain?

1. A concise explanation of the problem you’re experiencing.

**I’m trying to draw lat/long, or mgrs grid lines over terrain. I noticed that using a using the SingleTileImageryProvider works really well, but mapping the current view to the positions the lines should go is really hard(unless someone has figured this out??). This is essentially what a shader would do, but the math to convert the mgrs points to lat/long to Cartesian is really intense. Anyway, just wanted to see where vector 3D tiles support was at? Is there a timeline or anything that I can pass along to my managers? This is a really big deal and I’ve spent a lot of time trying to work within the current API to make the powers to be happy. **

2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.


3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

4. The Cesium version you’re using, your operating system and browser.

Version 36, but we’re upgrading to 38 next week.

Hi Scott,

3D Vector Tiles support work is being done in a branch here. A lot of work has been concentrated on classification and on performance by moving the more intense calculation to a web worker.

I don’t have a date for you, but contributions are welcome and would definitely help move things faster!
