1. A concise explanation of the problem you’re experiencing.
I have a few different entities which have defined two different display graphics(billboard and model, or billboard and polyline). I’d like to flip the display from the billboard to the model/polyline when the camera is near or far to the entity. Is there something to do this that I’ve missed? The DistanceDisplayCondition offers something similar but that is defined in the billboard not at the entity, and there’s no callback to do anything custom.
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.
