Where can I find information about BSP trees and PVS organization and programming algorithms ? Thank You.

You might wanna check out tricks of the windows game programming gurus by andre lamothe. There is a whole section on bsps and algorythms.

Cheers

This is not true. In this book there''s neither information about
PVS nor BSP. PVS is covered almost nowhere. Only at this site under Dan''s tutorials is a short article about PVS.

I was wondering if there are any good open-source programs that use bsp/pvs? I could use them to learn from.

Yes, know this ? http://www.idsoftware.com/archives/sourcearc.html

Stupid me... forgot that they relaised some stuff under gpl.
thanks!
