Advanced culling technic in ogre? Like CHC++?

Post by lmas19820607 »

I think Ogre really need to implement a occlution culling technic.
Without the oc, the scene like crowd city can't be rendered efficiently.
In real commercial project, it's really important.
I am not sure, but maybe that was why there isn't any big commercial project using Ogre, except fixed camera scene like TorchLight.

Kidding aside:
Yes, people have tried to implement CHC++ in Ogre, but it didn't take off.
Tuan Kuranes and Praetor would be the two obvious ones to ask.

Praetor has been working on a CPU-side scene manager for occlusion culling -- I'm sure he'll announce it when it's ready. ;)
Do you need help? What have you tried?

Working on it. Culling is a an area that explodes when you start peeling back the layers. There's so many possibilities and choices. Different ways of combining different techniques. I'm in the thick of it right now.
