The Lightning Artist Toolkit (Latk) provides a complete pipeline for hand-drawn volumetric animation—a common exchange file format, a set of ML models, and plugins to integrate 3D drawings into a wide range of XR projects. Readable in any popular 3D graphics application and ready to use in real-world production scenarios, Latk's goal is to make creation in 3D as expressive and intuitive as drawing in 2D.
