I'm trying to get Cesium to gracefully recover after a crash. I've got showRenderLoopErrors set to false, and I'm listening for the renderError event. When it happens, I clear all the drawings and all data sources (entities.removeAll, dataSources.removeAll). I reset the camera back to the "default earth" view. Then I resume rendering by setting useDefaultRenderLoop back to true. This allows me to continue using the viewer. However, it normally fails if I try to create entities again.
Is there some way I can completely reset the viewer back to its initial state so I can completely recover from the crash? For example, completely emptying the render queue, etc? There must be a way to clear the internal state of the viewer after it has become corrupted so I can create entities again. Any advice on how to go about attempting a crash recovery?
My next avenue will be to load a new viewer upon an error and start again, but obviously this is clunkier and less desirable than simply resetting the internal state of the existing viewer. Thanks in advance.
