Question about the internal parts of Unity

News & General Discussion

This is really geared toward the OTEE guys, and probably more specifically Aras and Joachim. How does Unity handle scene management and visibility tests? I know a lot of smaller engines use Octrees, BSPs or some type of k-d trees, but this seems primitive for an engine like Unity. I’m not looking for a very technical answer, a simple “We use…” would suffice :stuck_out_tongue:

Thanks,
Jedd

We use frustum culling and make it really fast :slight_smile:

Thanks :smile: (I’m sure PhysX handles some of the issues with collision testing also that would go on with scene management).

Thanks Aras!

PhysX using sweep-and-prune combined with something, I think. Not sure what exactly, I checked that ages ago.
