PhysX-Omni: 3D Generator — What It Does and What You Need to Run It

PhysX-Omni is an open source 3D generator that handles the image-to-3D task. As described by the authors, it is designed for unified generation of physically correct 3D objects ready for simulation: rigid, deformable, and articulated.

What it does

The tool takes an image and creates a 3D model from it. The authors describe the project as "Unified Simulation-Ready Physical 3D Generation for Rigid, Deformable, and Articulated Objects" — that is, they claim support for generating three types of objects: rigid, deformable, and articulated. The repository lists the tags 3d, image-to-3d, and physical-modeling.

What you need to run it

The code is written in Jupyter Notebook and published on GitHub. The largest model weights file takes up 4.6 GB, and the full set of weights is 15.4 GB. The weights license is MIT. The code license is S-Lab License 1.0: non-commercial use only, commercial use requires permission. The repository was created on May 20, 2026, and the last code change was on June 11, 2026.

Who it suits

The project may be of interest to those working on generating 3D models from images and needing objects suitable for physical simulation. The open source code and the available repository make it possible to study the implementation and adapt it to your own tasks.

The tool is unlikely to suit those looking for a ready-made application with a graphical interface: the code is provided as a Jupyter Notebook, which implies working in a development environment. You should also take into account the size of the weights — 15.4 GB in total — and the S-Lab License 1.0 code license, which permits non-commercial use only.

PhysX-Omni is an open research tool for generating physically oriented 3D models from images. Its practical value depends on the specific task and on your willingness to dig into the code and the license terms.
