# NeRF & DreamFusion

## NeRF

From a diffusion model we can generate several images of a scene or object from different views -> NeRF -> 3D model

## DreamFusion

DreamFusion uses StableDiffusion to generate several images of the same object/scene/person from different points of view. These pictures are passed to a NeRF model to generate a a 3D object
