Generate Synthetic Data with NVIDIA’s Omniverse Replicator Lightning App (beta)

NVIDIA and Lightning AI introduced the beta Omniverse Replicator Lightning App at SIGGRAPH to help machine learning researchers create synthetic, physically accurate 3D training datasets without the expense and effort of collecting and annotating real-world images. Users can select built-in environments and assets or upload USD, STL, and OBJ files, then randomize object placement and rotation to generate varied rendered images with ground-truth bounding-box annotations for object-detection training. The app enables users to preview and refine datasets, generate samples, launch computer vision model training through Lightning with configurable hardware usage, monitor jobs, download checkpoints, and compare model performance on synthetic and real images. Available for free through a Lightning AI account, the beta also invites user feedback on features and desired library environments.
