Infinigen – Create Realistic 3D Scenes with Blender

Infinigen is a 3D scene generator using AI. It works with Blender and was created by Princeton Vision & Learning Lab. Infinigen is a free and open-source software. In this article, we will explore what Infinigen is, how to use it, its key features, benefits and limitations.

Key Features of Infinigen

Infinigen is a procedural generator that generates everything from mathematical rules. This means that every asset in an Infinigen scenario is generated from scratch using a set of mathematical rules, from the macro structures to the minute details. This enables Infinigen to build an infinite number of scenarios each with its own distinct appearance and feel.

Here is the example code for Petal Parameters:

# Petal Parameters Density = uniform(20,5) Curl = uniform(0,50°) Length = normal (.03,.01) Wrinkle = normal (172,273) def make asset (*params):

Here is the output for Petal Parameters,

Infinigen’s Diversity

Infinigen generates a wide range of natural objects and settings like plants, animals, terrains, and natural phenomena such as fire, cloud, rain, and snow are all included.

The current emphasis on nature stems from the discovery that mammalian vision developed in the natural environment. Infinigen, on the other hand, is projected to improve over time to include architectural settings and artificial items.

Infinigen’s diversity is produced through a combination of procedural generation and data-driven strategies. Infinigen can generate an infinite number of items and scenarios via procedural generation.

By leveraging real-world data as a starting point, data-driven techniques enable Infinigen to build scenarios that are more realistic and accurate.

Real Vs Reel Geometry

  • Infinigen has been designed specifically for computer vision research, notably 3D vision. This means that Infinigen is intended to generate as realistic and accurate 3D scenes as possible.
  • Infinigen accomplishes this level of detail in part by employing real geometry. This means that all of the small details of geometry in an Infinigen scene are genuine, not manufactured. In contrast, several other 3D scene generating technologies use techniques such as bump maps and normal maps to simulate geometric detail.
  • Infinigen’s usage of real geometry assures that the 3D ground truth is correct. This is significant in computer vision research because it enables researchers to train and test their algorithms on data that is as realistic and accurate as possible.

Automatic Annotations for Visual Data

  • Infinigen can generate high-quality annotations for a number of computer vision tasks automatically.
  • Optical flow, 3D scene flow, depth, surface normals, panoptic segmentation, and occlusion bounds are all included.
  • Infinigen’s rendering engine generates the annotations automatically. This guarantees that the annotations are uniform and accurate.
  • Furthermore, users have complete control over the rendering process, allowing them to tailor the annotations to their individual requirements.
