## Marble: A New Approach to 3D Worlds Fei Fei Li, often referred to as the "godmother of modern AI", has presented Marble, a generative 3D world model developed by World Labs. This innovative tool is based on Neural Radiance Fields (NeRF) and Gaussian splatting, offering an alternative to traditional rendering methods. ## Features and Performance Marble stands out for its speed and ability to generate explorable 3D worlds in minutes. Unlike videos, the created environments are not simple sequences of frames, but real, persistent and editable 3D spaces. Users can expand regions, modify materials, and merge different worlds. The platform natively supports virtual reality (VR) and it is possible to export the models in formats compatible with Unreal, Unity or Blender. ## Potential and Future Prospects Despite being in its early stages, Marble demonstrates remarkable potential. Its ability to represent complex 3D environments without triangle-based geometry or real-time rendering opens new perspectives for the creation of interactive and immersive content. The platform offers free options for experimentation and paid plans for more intensive use.
