Simulation determinism, Parallel processing.
Posted: Sun Mar 18, 2007 1:26 pm
Hello,
I am experimenting now with Bullet and have some question about it.
For my purpose the real-time is not as important as visual quality.
How to improve quality of the bullet's simulation?
I am also not quite sure how to increase Sub Steps with stepSimulation...
Another question is how to arrive deterministic simulation with Bullet?
So the two runs of the same simulation on the same system will get the same results.
Probably the first problem is the btRand2() from equentialImpulseConstraintSolver and static seed...
And the last question, how to use Bullet on Multi Core CPU's?
As I know there was some work for Parallel processing for Bullet, is this correct?
I am also working on Window 32-bit, 64-bit and Intel,PPC MacOSX, fortunately Bullet is pretty portable.
Thank you in advance for any help and also for this Library!

Code: Select all
stepSimulation(stepTime, 1, 1.0f/60.0f)
