Infinigen- developed by Princeton Vision & Learning Lab- is an open-source procedural generator that allows users to create a wide variety of high-quality 3D scenes. It is specifically designed for computer vision research and is capable of generating realistic training data. By utilizing randomized mathematical rules- Infinigen can produce an infinite number of shapes- materials- and details. Its focus is on accurate geometry rather than artificial details- offering a range of generators for natural objects and scenes. Additionally- Infinigen provides automatic annotations for various computer vision tasks and encourages community involvement to enhance its capabilities.
