How can I create an arbitrary collision shape?

[maxxfire]

Hi , How can I create a collision shap like a bottle or a cup.
I mean does it has any API to do this. Or I just made it by Maya, and then import it.
Thanks!

There's no API to do this but the SDK contains a few examples.

• Your first choice is to look at maya to produce a .bullet file and load it up. See Bullet/Demos/SerializeDemo.
• OBJ parsing, see Bullet/Demos/ConvexDecompositionDemo. That's a bit crude in my opinion but it works.

I use this tool with a lowpoly obj file:

then I load the resulting .bcs file as my collision shape
