| This live demo allows you to control camera rotation and thereby generate novel viewpoints of an object within a single image. | |
| It is based on Stable Diffusion. Check out our [project webpage](https://zero123.cs.columbia.edu/) and [paper](https://arxiv.org/pdf/2303.11328.pdf) if you want to learn more about the method! | |
