These days, I'm doing some research on Occlusion Culling. There's no doubt dPVS is a great way for that. In the paper, "dPVS: An Occlusion Culling System for Massive Dynamic Environments", I found the words "A more detailed discussion of the algorithms and their implementations can be found in the dPVS reference manual[11] The library and the test scenes are freely available for research projects and academic institutions." I am very glad to see that. But where can I get the dPVS library? Can anybody help me? My eamil is: cmmfir@gmail.com

to Andy: Thank you very much for the information! Maybe I'd have a try to implement some key algorithms myself!
