Infinigen Procedural 3D Scene Generator for Computer Vision Research

What is Infinigen?

Developed by the Princeton Vision & Learning Lab, Infinigen functions as a procedural generator specializing in the creation of 3D scenes tailored for computer vision research applications. It leverages randomized mathematical rules to construct everything from macro structures to micro details, encompassing shapes and materials, ensuring unlimited variability in generated assets. Users retain control over the generation process by overriding default randomization parameters for customized asset creation.

The platform focuses on generating diverse objects and environments found in the natural world, such as plants, animals, terrains, and phenomena like fire, clouds, rain, and snow. Notably, Infinigen prioritizes real geometric detail over techniques like bump maps or full transparency, providing accurate 3D ground truth crucial for computer vision tasks. It also facilitates the automatic generation of high-quality annotations, including optical flow, 3D scene flow, depth, surface normals, panoptic segmentation, and occlusion boundaries, with customization options available.
