I have a code about octree - now,in order to load it I active the function : make_octree(&3d_model) - meaning that I load a 3d model and make an octree from it. now, what should I do to load alot of objects - make a giant 3d_model which contain all the models I need or something else? in this way I don't see how can I implement a collision detection. is there maybe an octree code that you can give me that not sepearte each model's verticies into the octree leaves but remain the model attached. or is there a octree code that uses this kind of octree to render alot of objects and also implement collision detection that you can give me.
