I am studying the use of SMPL human models in Omniverse and executing the relevant motion data in the AMASS dataset.
The first question I encountered was the difference between OmniJoint and Physics Joint, which one should I choose? And whether the two types of joint data can be converted to each other.
I hope someone who is doing related research can help guide me. Thank you very much.
I’m not e expert but if this helps
OmniJoint - joints more for traditional game engine characters for driving skinned meshes / mainly for animation driven characters / assets. So the joints are driven by animation data / clips.
Physics Joint - Physics based joints to work with physX, where you can define the physical property’s of a joint, attach colliders and setup physics based simulations. So your asset would move based on physics e.g. falling to the floor, hinge joints so parts bend in a set direction based on physical property’s.
Doesn’t seem like they are interchangeable, I’ve been trying to connect the two myself with no luck / noticed a few unresolved tickets with the same issues so might not be supported?
