Real-Time Physics Simulation Forum

Follow this tutorial. It'll get you up and running adding shapes and seeing things move about.

Thanks for your response! I'm going to try to tinker with your suggestions and see if they have a level of accuracy high enough for what I'm being asked to do. Unfortunately, what I'm working on is closer to rocket science than gaming, so it might require some tweaking.

If you want simple, you could just have an if statement where if the value is less than some threshold, set the value to 0.

Not sure if any of this will help you, but they're the first things that came to mind when I read your post. -Is the mesh you're importing only the brown arch part? Could the ground be getting added, too, which might be causing your collisions? -Have you tried dropping the mesh into one of the Bulle...

Hello Bulleteers, I'd like to be able to simulate the physics of an object experiencing the force from a blast. For simple cases, I can just use ApplyForce() to launch an object, but if I want a more accurate representation, I have to consider the fact that the force applied to the object varies ove...

If it can't find the headers, it's a source problem and not a linker problem. Make sure that the directory containing the headers is specified under Additional Include Directories (see the attached screenshot). Hope this helps.

I've experimented with using a list of vertices and triangles to create a GImpactshape in Bullet. You may be able to find more info on that via a forum search.

Do you have Glut? Those demos didn't build for me either and I assumed it was because I don't have Glut.

I *think* you should be able to do that pretty simply. Bullet can definitely apply the force the way you want, but the way it deals with friction is a little confusing to me. From what I know, it uses a scale from 0 to 1, where 0 is frictionless and 1 is complete friction. So figuring out how to get...

I saw this when I was checking out the other forum section last week. Maybe it would give you a foundation?

You have do do something like this:

I followed the same tutorial and ran into that problem. You have to change bool callbackFunc(btManifoldPoint& cp, const btCollisionObject* obj1, int id1, int index1, const btCollisionObject* obj2, int id2, int index2) to bool callbackFunc(btManifoldPoint& cp, const btCollisionObjectWrapper* ...

One thing I'm confused about is do I specify rolling friction onto the sphere or the body the sphere will be rolling on? From what I've read and toyed about with, you have to specify rolling friction on both objects. In the rolling friction demo, they set the friction on the ground shape like: body...

Do you use the setAnisotropicRollingFriction() function? I'm still pretty new to Bullet, but I've seen this used where rolling friction is used (like in the rolling friction demo).

Can you show us? I'd like to see what worked for you either by screenshot or video and/or code.
