Can you offer any advice on working with larger numbers of tiled imagery layers? I have some tiled weather radar imagery recorded at various times. When you go to a specific time on the timeline in Cesium I want to display a classic loop anim e.g. the last hour at 10 min intervals. Currently I’m doing this by creating 6 layers and cycling the alpha values. Some problems I’m having…
Trying to set up too many imagery layers runs into problems, presumably related to WebGL resources running out. e.g. if I try to load 20 frames instead of 6, or if I want to cycle other layers as well (e.g. satellite IR etc). I assume this will vary between clients as well.
If I do a lot of create/destroy I run into issues. Should I be trying to re-use providers or layers?
When zoomed in on a city and the user selects another time there is a large delay before the imagery is visible again as 6 layers simultaneously work their way down from tile level 0. I think skipping coarser tile loads has been covered in another thread and might be on the roadmap. Is there a way I could preference layers such that I could get one frame to resolve before another starts requesting tiles?
Any other ideas?
