Infinite Photorealistic Worlds using Procedural Generation

TL;DR

Infinigen is a fully procedural system that generates infinite, photorealistic 3D natural scenes and objects, providing diverse data for computer vision tasks without external assets.

Contribution

The paper presents Infinigen, a novel procedural generator capable of creating unlimited photorealistic natural scenes entirely from mathematical rules.

Findings

Generates diverse natural scenes including plants, animals, terrains, and phenomena.

Produces unlimited, varied training data for computer vision tasks.

Operates without external assets, ensuring infinite variation.

Abstract

We introduce Infinigen, a procedural generator of photorealistic 3D scenes of the natural world. Infinigen is entirely procedural: every asset, from shape to texture, is generated from scratch via randomized mathematical rules, using no external source and allowing infinite variation and composition. Infinigen offers broad coverage of objects and scenes in the natural world including plants, animals, terrains, and natural phenomena such as fire, cloud, rain, and snow. Infinigen can be used to generate unlimited, diverse training data for a wide range of computer vision tasks including object detection, semantic segmentation, optical flow, and 3D reconstruction. We expect Infinigen to be a useful resource for computer vision research and beyond. Please visit https://infinigen.org for videos, code and pre-generated data.
