Penn Researchers Combine Agentic Reasoning With Geometry Models to Build 3D Scenes From a Single Image

The HARMONY framework uses a hierarchical chain of thought to decompose a photograph before handing geometry to a visual foundation model, an approach that treats scene reconstruction as a planning problem.

A team at the University of Pennsylvania has published HARMONY, a framework that converts a single image into a 3D scene by combining a hierarchical chain-of-thought controller with a visual geometry foundation model, according to the autho…
