Re: Frame Rate Independence

i dont understand anything anymore... are you not the same person whom Erwin wrote: Again, if you want to manage time and substepping yourself, with similar behaviour to ODE, disable substepping, don't use/create motion states and use stepSimulation(deltaTime,0); and you said: Yes, thanks a lot, it ...

Re: Frame Rate Independence

thanks.. ok, i see all that.. something... numbers... submarines... rainbows it all looks fine, except that little bit there which is horribly wrong, so maybe some problem in the test? your comment is most valuable to me... i dont absorb numbers well and im not really sure whats happening there with...

Re: Frame Rate Independence

its good to have someone to talk to about this... cheers! i still have no idea if iam reporting a bug or my stupidity here.. anyway, ok, that looks all good to me.. not really testing the case in question? - because you still use (dt, 0)? - you have plenty of time left to sleep() after each simulati...

Re: Frame Rate Independence

I used the term "newbies" to refer to simple apps.. you are right, sorry... i did exaggerate there a bit because i was struggling to prove my point otherwise ..i felt it was worth it BTW, in the end, it looks like Bullet works exactly as i expected, and the only problem seems to have been...

Re: Frame Rate Independence

a.) Bullet features 2nd kind of "frame-rate Independence", which gives you FREEDOM to sync your timer and animation with Bullet's internal 60fps as you see fit b.) it can do 1st - "FALLING-framerate" Independence by using stepSimulation(dt, 0), but it is not deterministic c.) st...

Re: Frame Rate Independence

If the computer is too slow to perform the simulation substeps in real-time, this has nothing to do with failing 'Frame Rate Independence', but the simulation is too intensive for your computer ok, thats wonderful, i thank you ...allow me to take something out of that i havent come across so far an...

Re: Frame Rate Independence

It is your arrogant attitude that make us ignore you. Change your attitude to be more friendly, or get banned. The CcdPhysicsDemo 'stepSimulation' is framerate independent. English is not my 1st language, i made clear that im stupid, that i do not understand and merely seek explanation - but it did...

Re: Frame Rate Independence

i dont understand how every single one of my questions that started this discussion ended up ignored, together with almost everything else i said later on? chunky, Abaraba: OK, one last attempt before I quit responding to this. what does that mean? ..you dont really have to, and i wish there was muc...

Re: Frame Rate Independence

If a computer is too slow to compute all required simulation time steps in real-time, I suggest to either buy a faster CPU, improve the physics simulation performance or simplify the simulation. computer is 2ghz with ati Xpress and latest drivers and im talking about simple Bullet demos like "...

Re: Frame Rate Independence

chunky, Assuming you're passing time in milliseconds instead of seconds... they say assumption is mother of all fuk-ups ;-) but seriously, you might be right for all i know, i have no idea about that function i just copy/pasted it as it was already used as example, illustrating that i tried differen...

Re: Frame Rate Independence

sparkprime, im not quite sure what is it you're saying in regard to "Frame Rate Independence", except that stepSimulation() is confusing... - does that mean you agree with "my" definition here of "Frame Rate Independence" and you too are unable to achieve that effect wi...

Re: Frame Rate Independence

http://www.bulletphysics.com/mediawiki-1.5.8/index.php?title=Stepping_the_World "Stepping The World" article says this: maxSubSteps == 0 ? If you pass maxSubSteps=0 to the function, then it will assume a variable tick rate. Every tick, it will move the simulation along by exactly the timeS...

Re: why Bullet demos feel like happening on the moon?

and so, thanks to simple misunderstanding i guessed it right without even knowing what i was talking about really.. how strange at least right about what i was talking about, still not quite sure if we were all talking about the same thing.. anyway, as i said - just change stepSimulation arguments t...
