What is Infinigen?

Infinigen is a research project developed by the Princeton Vision and Learning Lab, which aims to provide unlimited high-quality 3D data for computer vision research. It is based on Blender, a popular free and open-source 3D creation suite that supports modeling, animation, rendering, simulation, and more.

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. This means you can create any scene, from underwater landscapes to snowy mountains, tropical forests to urban environments.

How does Infinigen work?

Infinite uses a modular system of generators that can be combined and customized to create different types of scenes. Each generator has a set of parameters that can be adjusted to control the appearance and behavior of the assets. For example, you can change the number of trees, the water’s height, the fish’s size, the sky’s color, and so on.

Infinigen also provides a user interface that lets you easily select and modify the generators and preview the results in real-time. You can also export the scenes as Blender files or images with labels for each object. Infinigen can generate scenes at different resolutions and levels of detail, depending on your needs and hardware capabilities.

What are the applications of Infinigen?

Infinigen was originally designed for computer vision research, as it can provide large amounts of labeled data for training and testing algorithms. However, Infinigen can also be used for other purposes, such as:

• Game development: Infinigen can help you create realistic and diverse game worlds without spending hours modeling and texturing. You can also use Infinigen to generate variations of existing scenes or to create new ones on the fly.
• Film making: Infinigen can help you create stunning backgrounds and environments for 3D animations or live-action movies. You can also use Infinigen to add details and realism to your scenes or to create special effects.
• Education: Infinigen can help you learn about 3D modeling and procedural generation by letting you experiment with different parameters and see how they affect the output. You can also use Infinigen to explore different types of ecosystems and biomes or to create your fictional worlds.
• Art: Infinigen can help you unleash your creativity and express yourself through 3D art. You can use Infinigen to create abstract or realistic scenes, mix and match different elements, or add your touch to the generated assets.
