How would you simulate a RigidBody that is lighter than air?

Is there any neat way to simulate RigidBodies that should float? Right now I'm applying different gravity vector to every object that I want to be floating. Is there any other way?

Re: Implementing JBullet into Java Games

Bah! It took me fucking 5 days of debugging to finally notice that mesh.numTriangles should be actually number of triangles -1.

@JumperBR
Well, you could just scale your world down. Quite simple.

Re: Implementing JBullet into Java Games

Did anyone successfully simulated terrain in JBullet? How may vertices were you able to simulate with satisfying results? What shape did you use? Are there any optimizations i could do? Please, give some code snippet. Edit: One more question: Is the order in which I add points to ConvexHull shape im...

Re: Java port of Bullet

Ok, i got it working triangle stride should be 3 points, and vert stride 1 point. But I have another problem - simulation works as ConvexHullShape and also BvhTriangleMeshShape, but both are EXTREMELY SLOW. I reduced my mesh to 15682 polygons, and 7983 vertices, which is absolutely unacceptable, and...

Re: Java port of Bullet

Hi, could anyone post a snippet of a code on how to use TriangleMesh in JBullet? From what I see it's a lot different than original Bullet. I'm just trying to construct a simple static terrain mesh. I have no idea how to do that - ConvexHull works, but of course terribly slow ( terrain has something...
