Re: Fast moving bodies and tunneling

Do you mean tunneling like part of the object is in and the other is not? I think I have a solution for you if it's simple enough, set up a periodic check, let's say 5 times a second Now each time record the current position, and the linear velocity. Now cast a ray from the last position to the curr...

Re: How to create a bullet collision shape with mesh file

you take your points, and you shove it into a trimesh, then create a convex or concave object depending on your mesh.

Re: Cloth collision detection-What is the currnt stateof the

The issue is still up that cloth does not self collide.
Shouldn't that be updated on google code if it is the case?

Re: Stopping time for an object

Eh.. Why don't you just keep a buffer somewhere in your code that contains information about the freezed object. Then when the player freezes it, it copies the transform, the shape pointer, and the things like linear and angular velocity. Then remove that body from the world, but not the shape, and ...

Re: Bullet on GPU

It doesn't look like this thread has been updated since 2007, possibly 2006 regarding the status.
If this isn't live, and it isn't functioning, please remove the sticky status of this.

Re: Real-time voronoi fracture and shatter for Bullet Physic

@blenderdude The shattering at the moment seems to be manually applied, and it is just pre-splitting stationary objects, which when disturbed, breaks apart. It needs a lot of custom tweaking on the frames that involve shattering. I hope to take this and come up with a means to have shatter-able obje...

Re: appHACDDemo (and Convex Decomposition tool)

Might you put your work on github or bitbucket? (what license would you put your work under) I would like to fork it and implement an interface similar to how one would generate a concave triangle mesh directly, as an alternate to loading an OBJ or OFF. I'm really excited about this. Are you plannin...

Re: Real-time voronoi fracture and shatter for Bullet Physic

This is really cool! I wonder how well this could be implemented in a theoretically complete OpenCL implementation(including Bullet Physics). Are you still working on this? What are you releasing under?(I see copyright to you, and I see zlib for the bullet part, but not you) Additionally, how involv...
