I'm trying to solve this problem from quite sometime now but couldn't get a satisfactory answer. I have an object in the scene whose trail I want to draw. I'm adding lines to the polyline collection class. I also want to be able to place the object somewhere in the middle of it's path and remove/add trail track from present position to previous position ( Simply remove/add to top polyline from polyline collection object). Everything works great expect as the time passes and the trail is too long the performance starts to degrade. I'm looking at 1-2 fps with maybe ~3000 polylines in the collector object. Is there a better way of doing such a thing? I saw CZML demo, not sure if it can be used to draw trail/trajectory at run time.
Is there a way to generate secondary 3D window with same object representation but different angle?
