Title: TriDi: Trilateral Diffusion of 3D Humans, Objects, and Interactions
Content: TriDi is a unified 3D human-object interaction model that can generate or infer humans, objects, and their interactions in any direction, rather than only conditioning one modality on another. It uses a three-way transformer-based diffusion process and supports user control through either text descriptions or contact maps embedded in a shared latent space. With one network, TriDi covers seven conditional distributions, outperforms specialized one-way baselines on GRAB and BEHAVE, improves diversity, and generalizes to applications like scene population and unseen object geometries.
