Looking for performance guidelines for my use case

Hi all, after having read up on AABB trees and all the nice things that Bullet does, I'm wondering whether what I have in mind is insane or just what Bullet was built for. The use case is a space simulation (for a game, so realism can be traded off). Stars being orbited by planets being orbited by m...

Wiki partially offline

Some wiki pages load just okay, others respond with a connection abort.
E.g. this loads okay: http://bulletphysics.org/mediawiki-1.5. ... ics_format
This doesn't: http://www.bulletphysics.org/mediawiki- ... ialization

Determining Bullet version

Hi all,

I have this set of shared libs built from Bullet sources by another project, and I need to find out what version of Bullet that is.
Is there a way to glean that information from the libs?

Building just the libs

Hi all, I have zero knowledge of cmake, and I'm having serious trouble finding out which options to set and which options to leave alone. (I'm using a cmake gui tool so at least I see what options are there, phew.) Here's my use case: 1) Needs to use doubles. 2) Just compile the libs. Don't install ...

Re: Cross-platform determinism

@CookieMonster: The game industry reports that you can have cross-platform determinism if you very, very carefully avoid using anything that doesn't follow the IEEE specs to the letter, and avoid a handful of other pitfalls. So my question isn't whether it's doable; I'm pretty sure that the guys who...

Cross-platform determinism

With "cross-platform determinism", I mean that a simulation will give bit-identical results given the same initial conditions, sources of randomness, on a reasonable selection of platforms (can't expect bug-for-bug compatibility between an ancient 8087 and an AMD Turion). I see that determ...
