About NVIDIA Lyra
NVIDIA Lyra is an open series of generative 3D world models designed to transform casual image or video captures into explorable, 3D-consistent scenes. It provides both a graphical user interface and training code to support reproducible research, rapid prototyping, and controllable long-horizon world generation. Users can sample and navigate generated worlds interactively via the GUI or run feed-forward inference scripts for batch processing and multi-view generation. The tool reconstructs 3D and 4D scenes from single images or videos, enabling downstream evaluation, visualization, or integration into simulation pipelines. Lyra is tailored for graphics and vision researchers, simulation teams, robotics labs, and technical artists who require data-efficient 3D scene generation and long-horizon consistency. It also serves engine prototypers and content tool developers who need navigable scenes for previsualization, layout studies, or synthetic data staging. The codebase emphasizes reproducibility and evaluation, making it suitable for academics benchmarking long-horizon consistency and practitioners building internal baselines for novel view synthesis and world-model research. The Lyra 2.0 GUI includes a 3D viewport, camera controls, trajectory timeline, sampling parameters, and export options, while inference scripts provide console-based processing for batches of inputs.
