Re: [Opensim-dev] BulletSim testing

[Mister Blue]

Thanks all for testing. I have some Manti to fix. :-)

I'm travelling at the moment so I won't be on IRC for a few days. But soon
I will be back to making BulletSim run smoothly.

I have 2 test setups that switch to ODE quickly for comparison.
(we do a Havok comparison with copied vehicles) 

a Win 8/.Net ivy-bridge/16gb D2. (opensim-61b816e)
a Suse12.2 /mono sandy-bridge/16gb on OSGrid (opensim-61b816e)

Initially checked basic region asset and Avatar actions. Was only marginally
different from ODE. 

Ran a 1 prim way-point vehicle with identical rectilinear route and
parameters.
speed was slower and it ran the last side with pauses. Bullet (108 sec) ODE
(58 sec) Havok (57 sec).

Tried two sailboats and concluded the up-wind tacking switchover lag is too
large to do any meaningful tests.  
Friction did feel lower running downwind. Perhaps scripting can improve the
boat's vector changes.
(tacking is pointing a boat into the wind and running a zig-zag course)

[Opensim-dev] BulletSim testing

[Adams, Robert]

I have been working on a Bullet based physics engine for OpenSimulator.  It is 
in a fairly stable state and works pretty well as a regular physics engine.

If you have the time and resources, I invite testing and stressing. The version 
checked into 'master' sources works on Windows and Linux both 32 and 64 bit. 
BulletSim is turned on my changing the physics engine selection in 
"OpenSim.ini" - change "physics=OpenDynamicsEngine" to "physics=BulletSim". 
That's it!

Brakages should go into Mantis (Category: "[REGION] Physics Engine", Physics 
Engine: "BulletSim"). I especially want vehicles to work - any input on what 
needs fixing or tuning would be great.

Thanks.
