Spell is an AI model launched by Spline that can generate complete 3D scenes from a single image. It is based on diffusion model technology and trained by combining real and synthetic data, capable of producing 3D worlds with multi-view consistency in just a few minutes. The major advantage of this technology is its ability to generate high-quality 3D scenes quickly while supporting various rendering techniques such as Gaussian drawing and neural radiance fields. The advent of Spell has brought revolutionary changes to the field of 3D design, allowing creators to generate and explore 3D scenes more efficiently. Currently, Spell is still in development, and the team plans to frequently update the model to enhance quality and consistency.
