1. A concise explanation of the problem you're experiencing.
Not ideal behavior when attempting to attach features to terrain on lunar surface.
There's notes in the sandbox link below but i'll summarize here:
- polyline clampToGround does not seem to work at all
- point and label features work but have some behaviors that seem to deviate from what I see in the sandbox Clamp to Terrain example. Seem to be partially hidden more often, also disappear if i zoom in too far on them.
- polygon seems like it tries to clamp to terrain, but ends up mostly hidden
- all features seem to disappear as i tilt the camera to look as is from the crater surface
I understand Clamp to Terrain is a work in progress! Hope this is helpful and happy to contribute just not super familiar with the internals so any guidance as to where the problem areas might be is appreciated.
Thanks in advance
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
The below is a map using lunar terrain tiles with some features drawn on it near Tycho crater
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
Showing labels and lines and shapes on the moon!
