hello.
I'm still studing the bsp and other space partitioning tecniques In a book on math (before testing all the opengl or directx I would understand math)I not understand:
1)the partitioning of the space must be done as preprocessing?because i read that is too complicated and computationally heavy for do it at runtime.
2)if the first question is true , how an engine preprocessing tool can do this?
I read that collect all the convexes objects?
why(i would understand)?
next .there are some tool for do this?

thanks

Do not use BSP. They are too slow to build... Try some kind of BVH, they are efficient, and pretty fast to build (and fast to traverse too). There are a lot of techniques that are allow you to build them even on the gpu.
