Currently, each point’s coordinate is taken from CZML obtained by propagating about 20,000 RSO’s TLE data.
With the coordinates, I displayed the RSO on the cesium viewer.
However, the frame rate was 2~4, which is horrible.
I tried various methods such as changing the propagate interval and interpolation method, but the frame rate did not improve.
When I draw only 3,000 RSOs in the same way, the frame increases to about 20, so it seems to be a problem because there are too many RSOs.
I would like to know how I can improve the frame rate while drawing 20,000 RSOs expressed in TLE data format.
Do I need to use a method other than drawing by CZML?
