Real-Time Physics Simulation Forum

with the one in your fork without threading included


I did not notice any significant speed difference when going from the latest trunk to your version when threading is not enabled

EDIT in this version is it possible to ray cast from multiple thread ?

The latest patch seem to have fixed it good work Also when my simulation consist of only 10-12 rigid bodies isolated by huge distances (talking millions of units here) this seem about 10% slower but as soon as it gets crowded around one of these base island this version seem to take the upper hand a...

Alright so after fixing my issue with Bullet I found an issue when using the GIimpact mesh


It crash on this method btGimpactShape.h line 846

yes I found it out I mixed up the method I use to add other object with the one I use for rigidbody when refactoring one of the class I use to manage bullet

I found it the rigid body added by world->add collision object glitches out

Well so far it's working good but I have other issue with bullet physics that until resolved prevent me from testing more in depth

I have an issue where i'm creating several rigidbody and I add them to a world most of them will work fine but randomly some of them won't seem to accumulate any velocity they just stick there and do nothing they at most sidestep other rigidbody when they are penetrating but that's about it once the...

EDIT: This is working great any chance this would get merged back into the main trunk

alright the reason is that xgetbv is a 64 bit pointer related instruction this is why it crashes on 32 bit windows I have no idea why bullet uses it 32 bit build

cheq that in the project property ->c++ -> code generation ->enhanced instruction set you are using sse2 and not avx
also do you have a 32 bit windows or a 64 bit?

i do understand i'll have to test how much i can stretch with just those update but in no case i see where telling bullet something happened in the past could help because in any case i can just tell the client this happened and now the motion state of those implied is that because i don't get what ...

I had similar issues with the HACD and no answer so I just let it go but if any one could help that would be great

attach it with a constain like in the ragdoll example and use forces to control it

a kinematic is an object that will not respond to collision

so you could emulate it like it's done in the kinematic controller

or you could use a dynamic object and control it using forces

if you are using bullet double precision you can technicaly fit a somewhat realistically sized solar system using 1 = 1 meter
but ya what ever float your boat as long as the floating point error does not get in your way

how ever irrlicht will really not like you at this scale
