I currently use heightmap format terrain tiles and looked at the spec recently and was surprised to see that the format is now deprecated:
"This file exists for historical reasons. This format is deprecated and should not be used. Consider quantized-mesh instead."
I searched and did not see any announcement or other info about this, and I would like to learn more:
1. Most importantly, is there a timeline for when support will be removed from Cesium?
2. Are there any current or planned features that are incompatible with heightmap terrain?
3. Was there an announcement for this? I'd like to keep abreast of changes like this, so I'd like to know where I should pay attention.
4. Why is heightmap being deprecated? I understand quantized-mesh is considered better for rendering, but heightmap is simple and much easier to generate tiles for.
Thanks,
Jacob
