Bullet3 is a professional physics simulation engine designed for calculating rigid body, soft body, and collision dynamics within 3D environments and robotics applications. It functions as a computational framework for determining complex geometric intersections and contact manifolds between objects in simulated space.
The library distinguishes itself through a distributed rendering framework that scales heavy graphical workloads and scene generation tasks across large clusters of machines. This capability enables the production of massive datasets by distributing complex scene generation across thousands of connected systems to minimize total completion time.
Beyond its core simulation capabilities, the project serves as a synthetic data generator for computer vision research. It automates the creation of photo-realistic video scenes and exports detailed metadata, including instance segmentation masks, depth maps, and optical flow data, to provide ground truth for training and validating machine learning models.
