View Full Version : Bullet for a collapsed skeleton

10-17-2013, 06:00 AM
Can anyone point me at a tutorial for getting started with the bullet physics?

What I have in mind is that I need to create a skeleton laying on the ground, and I have the skeleton mesh (upright). It occurs to me that by letting it drop to the ground using the bullet physics stuff, I could get a selection of good credible arrangements of the bones by dropping it at different angles.

You want it to remain connected? I don't know if Bullet has gotten hinge constraints yet. If not, how about trying IKB dynamics?

No, a pile of bones is fine, like the corpse fell a long time ago and the bones have settled.

If the skeleton is an object on a single layer, just make the skeleton a Parts Body (rigidbody with type set to parts), maybe set collision shape to convex (for speed) and place a passive body floor object and run the simulation, tweak to your liking.

Thanks Red, sounds like what I need.

I was thinking more about how to get started though, and the most introductory level never having used this stuff before...

It's really simple setup wise (also very limited options wise unfortunately as it is a closed system).
I suggest downloading the LW 11.6 addendum PDF from your Lightwave3D account page, it contains a pretty straight forward getting started with Bullet.

Ah right, I'm on 11.5, and was not aware of that doc, sounds like exactly what I need.
