Hello :)
I would like ask, if you know any other good way, how to manage mesh instances like frustum culling, octree etc.

My idea is to make octree for every mesh

My octree dynamicly removes empty cells or creates new one, when mesh is inside that cell. Contains only mesh list, cell size,position,cell parent pointer and root pointer, so it should be relativly small.

When i want to render it, i will go though all visible cells and make an array with information about position a color then render it as instances.

What do you thing about this technique ?

Thank you very much ;-)
