PhysX-Omni: 3D generator — what it does and what you need to run it

PhysX-Omni is an open source 3D generator that tackles the image-to-3D task. As described by the author, 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,” meaning 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 is 4.6 GB, and the full set of weights is 15.4 GB. The weights license is MIT. The code license is non-standard; the authors do not specify its type directly — you need to check the terms manually before use. 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 with 3D model generation from images and needing objects suitable for physical simulation. The open source nature and the presence of a repository allow studying the implementation and adapting 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 presented as a Jupyter Notebook, which implies working in a development environment. Also, consider the size of the weights — 15.4 GB in total — and the non-standard code license, which needs to be checked separately.

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