Re: Wrong fall height calculation
Thanks Basroil! About question 1: I've just started Bullet, and I just saw the time tuning can be done in stepSimulation() function. So if I use "stepSimulation(1,0)", it means that at every step, simulation will go 1 second forward and without any internal stepping (since the second param...

Monitoring forces between rigid bodies
Hi, In the hello world example I am trying to monitor forces between the falling sphere and the ground. So I added this command in the simulation loop: cout<<"Fz= "<< fallRigidBody->getTotalForce().getZ() <<endl; But I get always the force of "Fz= 0". Even after sphere collided t...

Wrong fall height calculation
Hi, I just started working with bullet. (Actually, I had a relatively hard time understanding stepSimulation function and its related arguments.) I began with "helloWorld" tutorial, however, I have found a small issue with calculation of the falling height. I have 2 questions: 1) With the ...

Bullet in blender: capabilities and limitations
Hi all, I am new to both blender and bullet. I am doing a research dealing with capabilities of physics engines (e.g Bullet physics) and their accuracy in simulating physical phenomenons as an engineering tool. During my studies I found out Bullet is integrated in blender and made it very easy to wo...

Re: What kind of damping Bullet uses? :?:
Mybe I need to clarify better: There are different kinds of damping: one is "mass damping" which is a coefficient multiplied by velocity; and "non-viscous damping" which is a coefficient which multiplied by unbalanced force. What is the type of damping Bullet physics uses? :?: :?:

What kind of damping Bullet uses? :?:
Hey, I am new to bullet and I started using it in blender. In the physics engine tab, I see damping can be specified for both "translation" and "rotation" My question is that does bullet use the concept of "mass damping" or "non-viscous" damping? :?: Thank you...

Re: Error in compilation
Bullet doesn't use SDL. You forgot to add the OpenGLSupport library. You better use a build system that ships with Bullet, such as premake or cmake. It should compile out-of-the-box. See the instructions in the docs folder. How to add OpenGLSupport library in the command I should type? (where shoul...

The equations Bullet Physics uses for solving physics system
Hi, I'm student and I am going to evaluate whether Bullet Physics is capable of simulating physical phenomenon accurately or not. But before that, I need to study and to know what kind of equations Bullet uses to solve physical systems. For instance, for friction, for rigid body and soft body. How d...

Re: Error in compilation
nullChar wrote:This isn't really a Bullet build issue, but a dependencies problem. You're trying to link the SDL and SDL_image libraries, but they don't exist on your machine.
Find the library files for SDL and place them within your library directories and it should link correctly.
Thanks

Error in compilation
Hey, I am very new to Bullet (a few hours!, version 2.82), linux (I am using Ubuntu 13.10) and programming! I just installed Bullet physics on my ubuntu. I tried to compile the Helloworld example using this command in the shell: g++ *.cpp -lSDL -lGL -lGLU -lSDL_image -lBulletSoftBody -lBulletDynamic...
