Usable for placing alot of objects (like imposters into your scene).

Example application for usage would be :

- Grassing large areas or vegetation in general.
- Make a forrest of thousands of tree's
- Create cities with thousands of buildings
- Clouds.
- Asteroid field (or saturn rings?)

Simply for whatever you need alot of

Project contains a 16x16 grid in the x,z plane.
It always checks the 256 grid nodes, ..but searches only the nodes in the frustrum.
If a grid node is found, it looks for imposters and then renders only those, excluding imposters not in frustrum.
This makes it very fast, instead of searching all 50000 imposters,
it seaches (256 num nodes)+(nodes in view*imposters registered in each), typically :

256+16*195 = 3376 checks which is alot less than 50000 checks

Have fun.
