The project I am doing is to visualize data.
For example, I retrieve four JSON files, which are longitude, latitude, time, and the value that corresponding to longitude and latitude, then display them on the globe.
The way I am doing is that I used Extent to draw a lot of geometries on the globe, then used clock.onTick event to trigger a function to reset the color of the geometries to make an animation effect. The problem with this approach is that it rendered really really slow, so I think maybe I could try with imagery provider. I also considered to convert the JSON files to CZML, but the JSON files are sometimes over gigabytes. The converting cost could be very high.
So what might be a fast way to do this in Cesium?
