Obi is an advanced particle-based physics engine capable of simulating a wide range of deformable material behaviors. It depends on the Burst, Jobs, Collections, and Mathematics packages. With Obi Softbody, you can simulate complex elastoplastic softbodies composed of thousands of polygons, complete with collisions, self-collisions, and rigid body interaction. Softbodies are physically represented by a set of ellipsoidal particles held together by shape-matching constraints, allowing them to deform both elastically (restoring their rest shape) or plastically (absorbing some of the deformation into their rest shape).
