I have a very large kml file that displays major roads for country that I need to display. The zipped and formatted kml file is 88MB and 2.8 million lines long, and not surprisingly, it doesn’t load into cesium.
How many lines do we expect cesium to be able to render at 30fps? Are there any possible performance enhancements? Could I parse the file myself and stitch the lines together with a series of Entity->Polylines. Are there any other possible solutions? Has anyone else tackled a problem like this? Possibly storing the data, and then creating the lines when the camera is zoomed in to a certain point, kind of a LOD approach?
