-characters dynamically updating their physics bounds
-armature deforming mechanical objects
-dynamically updated bounds when a mesh is replaced
-tentacled creatures where each tentacle can collide with objects independently because of the dynamic updating of bounds
He mentions this is a frequent requent from these forums and now you have it, enjoy.
BTW: Don’t forget Benoit’s latest work for the BGE as well (the IK algorithm)
This is perfect for a real-time sculpted level editor (as seen in WC3, for example)- also, average framerate for intensive stuff (such as this will probably be) can be improved by updating once every X frames (or splitting up which objects are updated on which frame)
I don’t know the framrate hit, but I doubt it would be viable to update even one character regularly, and expect to be able to do anything else (I could be way off base though) if you want a character to interact with the environment, it’s probably best to have a collision object set to cylinder parented to each bone.
Or you could divide the terrain in little tiles as different objects and just update the small parts that are being edited. Unless for whatever reason you wanna change the whole planet 60 times every second, then that could slow you down
