Real-Time Physics Simulation Forum

- my game world is setup with an octree, each node containing static geometry. in ode i could create a separate space for every octree node to speed up simulation. is there a simular way in bullet? so far i just add each mesh to the world itself. I was wondering about this too, when I switched to b...

Is there any progress on this?

Thanks,

I implemented another joint type: btHingeConstraint *btJointCreateHinge (btRigidBody *body0, btRigidBody *body1, const btVector3 &anchorPos, const btVector3 &axis) { btTransform frameInA, frameInB; frameInA.setIdentity (); frameInB.setIdentity(); frameInA.setOrigin (body0->getCenterOfMassTra...

i have just implemented a ODE like fixed joint: btGeneric6DofConstraint *btJointCreateFixed (btRigidBody *body0, btRigidBody *body1) { btGeneric6DofConstraint * joint6DOF; btTransform localA, localB; localA.setIdentity(); localB = body1->getCenterOfMassTransform().inverse() * body0->getCenterOfMassT...

thank you, this was exactly the type of explanation I was looking for.

I'm creating my ragdolls (see demo1 or demo2 ) using the data from an OGRE skeleton. Then I have an aditional XML file which descripes shapes and joints, see attached skeleton.zip Now I create a body for each bone and the joints. Creating the bodies is not the problem with bullet. Only one thing: I'...

thanks for the fast answers. For my ragdolls I'm using this code in ODE: hinges: j = dJointCreateHinge (getGameWorld()->getWorld(), jointGroup); dJointSetHingeAnchor (j, anchorPos.x, anchorPos.y, anchorPos.z); dJointSetHingeAxis (j, axis.x, axis.y, axis.z); dJointSetHingeParam (j, dParamLoStop, minA...

Hi, this weekend I took some time to integrate Bullet into my project. Coming from ODE I have to say I really like Bullet, it has a good C++ interface and already great features. But I have a few problems with it: 1. My ragdolls aren't working, which is probably because I don't really understand the...

thank you for the fast answers. I'll comment it out for now.
@Dragonlord: I'm using gcc-Version 4.1.2 (Ubuntu 4.1.2-0ubuntu4)

Hi, I get this error when compiling bullet in 64-bit linux: C++ ./out/linux/optimize/src/BulletCollision/CollisionShapes/btOptimizedBvh.o src/BulletCollision/CollisionShapes/btOptimizedBvh.cpp: In member function ‘bool btOptimizedBvh::serialize(void*, unsigned int, bool)’: src/BulletCollision/Collis...
