Re: damping a function of velocity
Hi sparkprime, thanks for you reply! that is the only damping I'd guess it has to be....angular damping and linear damping are the only damping?! and yes, the factors you supply are the proportion of velocity lost per second. damping = -kv -> I set k in the damping function btRigidBody::setDamping (...

damping a function of velocity
Hi there, as I read in the last entry of the thread http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2718&p=10875&hilit=damping+velocity#p10875 damping is dependent of velocity. Does this apply to linear and angular damping in the btRigidBody::setDamping (btScalar lin_dampi...

Re: timesteps
Hi ejtttje,
Thanks for your answers!
One more question: when my simulation runs slow motion (Q3) or faster (Q4), what exactly is the idea of fixed time steps?
Cheers Leo

timesteps
Hi there! I have some questions concerning the use of time steps in bullet. As I could read in the forum and manual, bullet is working with 60 frames per second (fixedTimeStep). But there is the possibility to set time steps in the class btDiscreteDynamicsWorld with the function stepSimulation(...)....

public const btVector in class header file
Hi there, I'm trying to create a public const btVector3 in a class header. Somehow it did not work because the btVector3 is not a native C++ variable... #include "btBulletDynamicsCommon.h" #ifndef Test_H_ #define Test_H_ class Test { public: Test(); // constructor ~Test(); // destructor co...

Re: Hello World...
Hi Dominik, thanks for your reply! Good argument with the compilation.... Concerning the linked libraries: I include (as default in the HelloWorld) btBulletDynamicsCommon.h file in which the rest of the includes for all the other .h files is defined. As far as I understand it there is no need to inc...

physics engines: comparisons, performance tests, benchmarks
Hi all. I'm looking for comparisons, performance tests, benchmarks and similar documentation the following physics engines: - Bullet - PhysX - JigLib - Newton - ODE - Tokamak - True Axis - Havok - Impulse-based dynamic simulation - Simple physics engine - ... I know that Adrian Boeing did a very goo...
