Abstract

The advancement of Embodied AI requires high-quality simulation assets that faithfully mirror the physical world. NeoWorld-Pro reformulates monocular scene reconstruction as a procedural programming task for interactive 3D environments. It leverages multimodal large language models to translate a single RGB image into executable programs defining object geometry, articulation, physical properties, and scene layout.

To ensure simulation readiness, NeoWorld-Pro introduces a physics-in-the-loop mechanism that executes generated programs in a physics engine and iteratively refines them using simulation feedback. The resulting scenes support stable stacking, fine-grained manipulation, and articulated object interactions that are difficult for open-loop reconstruction pipelines.

Dataset and Benchmark

A multi-object simulation benchmark for physically executable scenes.

NeoWorld-Pro is evaluated on PartNet-Mobility and a newly constructed synthetic scene benchmark designed to stress-test monocular reconstruction in physically realistic multi-object environments. The benchmark tasks cover placement, assembly, articulation, and interaction with task-relevant affordances.

Across 84 downstream manipulation tasks, NeoWorld-Pro achieves a 92.85% task success rate.
