Infinigen Indoors: Photorealistic Indoor Scenes using Procedural Generation

TL;DR

Infinigen Indoors is a Blender-based procedural system that generates diverse, photorealistic indoor scenes with constraint-based arrangement, facilitating training of embodied agents in real-time simulators.

Contribution

It extends the Infinigen system to indoor scenes by introducing a library of assets and a constraint-based placement system, enabling realistic scene generation for AI training.

Findings

Generated scenes are highly diverse and photorealistic.

Scenes can be directly used for training embodied agents.

Open-sourced with tools for easy integration.

Abstract

We introduce Infinigen Indoors, a Blender-based procedural generator of photorealistic indoor scenes. It builds upon the existing Infinigen system, which focuses on natural scenes, but expands its coverage to indoor scenes by introducing a diverse library of procedural indoor assets, including furniture, architecture elements, appliances, and other day-to-day objects. It also introduces a constraint-based arrangement system, which consists of a domain-specific language for expressing diverse constraints on scene composition, and a solver that generates scene compositions that maximally satisfy the constraints. We provide an export tool that allows the generated 3D objects and scenes to be directly used for training embodied agents in real-time simulators such as Omniverse and Unreal. Infinigen Indoors is open-sourced under the BSD license. Please visit https://infinigen.org for code and videos.
