Luma AI enables photorealistic 3D scene capture using Neural Radiance Fields (NeRFs) and Gaussian Splatting. Their Dream Machine model generates 3D objects from text descriptions or reference images, while the capture app turns ordinary smartphone video into explorable 3D environments. The platform is used by game developers, architects, e-commerce companies, and VFX artists who need high-quality 3D assets without traditional modeling workflows.
