Re: problem loading mesh from .bullet file

/offtopic: how are you exporting the mesh from 3dsmax? Last I checked the bullet plugins were only available for Maya.

If its not too much trouble would you also be able to confirm for me if this (clicky) is similar to the method you used?

Re: serializing / deserializing btBvhTriangleShape

I tried adding a rigid body to the physics world and serializing the world, but the mesh data still does not load correctly. Can someone verify whether or not this is valid data? (file attached) I had a look using the file inspector you linked me but the btVector3FloatData doesn't seem to be correct...

Re: serializing / deserializing btBvhTriangleShape

I don't understand - you yourself state in this thread that btCollisionShape::serialize() should be used for serializing a single shape. Is this no longer the case? If you choose to manually serialize individual collision shapes, you cannot use the btBulletWorldImporter to load the .bullet file. In...

serializing / deserializing btBvhTriangleShape

I'm writing a tool to convert an Ogre mesh file to a bullet file for use in our game. Problem is, I can't for the life of me get serializing / deserializing to work as expected; the triangle data produced is just plain wrong . I've been stepping through bullet all day long trying to find the cause, ...

Re: rotation not being simulated?

forgive my insulence!

I forgot to calculate the local inertia as I created each body *facepalm*

Re: rotation not being simulated?

if its any help this guy describes a similar problem (No rotation, even if he applies torque manually).

As far as I can tell his problem was also unsolved.

rotation not being simulated?

I've been working with bullet for a few weeks now (on and off) with Ogre and I just cannot figure out for the life of me why no rotation is being simulated. Just translation. When I create a line of capsules (For testing purposes), each with a slight overlap, they spawn inside each other and then ju...

btConeTwistConstraint rbAFrame and rbBFrame?

I'm developing a ragdoll simulation in Ogre using a series of btCapsuleShapes as the bones. I've been able to succesfully construct the bone hierarchy from an Ogre::Skeleton, however I've been unable to find the correct method of connecting them. Bullet's ragdoll sample hasn't been very helpful, wit...

Re: access violation in btCollisionWorld::updateSingleAabb

nevermind, I was creating a plane and allocating the StaticPlaneShape on the stack and it went out of scope. I was under the impression that Bullet made a copy of the shape, apparently not!

access violation in btCollisionWorld::updateSingleAabb

Hello! Unfortunately i'm enduring a bit of pain trying to use Bullet here... I'm getting an access violation inside of btCollisionWorld::updateSingleAABB on the line.. colObj->getCollisionShape()->getAabb(colObj->getWorldTransform(), minAabb,maxAabb); I've stepped into the function and it's crashing...
