I was just wondering if it's possible to have models that die using ragdoll physics with dark gdk alone.

You would need to to make your own physics one way or another - and for true rag-doll - I'd anticipate: Velocities, Joints, Rotational Velocities, and gravity.

Answer: Yes Fact:Not Easy
If DarkPhysics $$ is your issue - then ODE is free, Newton is free.

The REAL benefit of DarkPhysics is that the library already is integrated so a lot of mesh code memory pointers and directx stuff is done for you (Meaning not only is the physics part done - so is the whole DirectX->Ageia Physx communication regarding the DarkGDK lib. Quite a bit happens under the hood for you. This is where Lee and Mike Johnson kicked serious butt.

The draw backs to Dark Physics - are some features available in Ageia Physx API are not available or don't work the same way:

Vehicles (Number of Wheels Fixed...I THINK its not with Ageia Directly)

Dynamic Mesh - Even the documentation says it doesn't work with all meshs and might get discontinued. I personally have yet to take a MODEL (Even Dark Matter) and make a dynamic Rigid mesh body of it and see it work at all. This irritates me as if I model an Egg, I want it to roll to its side if I place it face up. Not choose BALL or BOX.

also Note - that from what I saw in the DBPro sample of the rag dolls - random crashes are not unheard of...could just be the DBPro version... also the effect was kinda slow (But I have a slow vid card and PC - I'll give it that) but if I increased the gravity a bit in the DBPRo demo - the Rag Doll effect looked more convincing to me in my opinion.

Thanks I guess I'll animate my charaters the old fashioned way
