I need to load a large scene, the model comes from UAV scanning generated, I hope to be able to smooth loading on most devices, including mobile phones. In my solution, I need to release objects outside the view (objects and materials are released), but I found that the BJS's own Frustum Clipping did not release the object outside the view, but I will use LOD, I will load multiple precision models, if not released, LOD will be meaningless, how can I do, I need to rewrite BJS code?
I tried to use incremental load, it did not release the memory of the object, but I found in Debug Layer when moving the viewport the total vertices in the change, I do not know what reason? But the total meshes not change;http://www.babylonjs.com/Demos/Espilit/
