Could you help me please.
I draw a lot of entities/billboards/primitives on page initialization. This approach kills performance dramatically, the page has freezing effect. How can I optimize it the best way?
Seems like I need to "redraw/rerender" entities/billboards/primitives that are within the current camera view region ONLY.
How can I get the current camera view region ?
How can I check that entites/billboards/primitives are within the current view camera region ?
Does "redraw/rerender" mean to remove entites/billboards/primitives from viewer and add the new ones) ?
Thank you very much.
