Event after finish drawing

[Mr_Fun]

What kind of data are you adding to the Cesium Viewer? Are you retrieving your data from Cesium ion? I do not know of any simple ways to check if your data has been drawn on your map. Does anyone else from the community have any suggestions?

I did find this community forum thread that seems to address an issue related to your question.

rendering is out of order. How to wait for rendering to finish?

I've created a prototype for a time series application that I am working on. I create a circle and then move it by 0.01 degrees to the east with each time step. I have this part working. However, the ordering of Cesium's event handling seems to be slightly off. Ideally, I should see a smooth transition where the circle moves to the right over a period of 5 seconds. What I actually see, is the circle generally moves to the right, but jumps backward every now and then. I have a hunch that the pr…

Let me know if you have any other questions or concerns.

Thanks for your reply, my data consists of large polygons, and I receive them from API - (backend)

Thank you for providing a few more details. I just have a few more questions that might help me get a better understanding of your use case. What data type are you importing? Which API are you using to import this data? In the meantime, I would be curious to hear your thoughts on the community forum thread that I shared in my last post. As mentioned earlier, I believe that your issue is at least partially addressed in the thread.
