I'm using Cesium for an app that calls for frequent tile updates. The question is, how would I go about reloading the modified tiles?
Poking through the source code to try and find a clue, I decided to try and hack that logic into queueChildrenLoadAndDetermineIfChildrenAreAllRenderable in CentralBodySurface.js, calling freeResources on any tile whose extent contains the updated lat/lon.
That worked, to an extent (no pun intended) - there's an update happening, but not for lower zoom level tiles. I'll keep messing with this solution for now, but I'm sure there are better ways to do this.
Any hints would be appreciated!
