| # LooseControl | |
| This is the official demo for the paper [LooseControl: Lifting ControlNet for Generalized Depth Conditioning](https://shariqfarooq123.github.io/loose-control/). | |
| Our 3D Box Editing allows users to interactively edit the 3D boxes representing objects in the scene. Users can change the position, size, and orientation of 3D boxes, allowing to quickly create and edit the scenes to their liking in a 3D-aware manner. | |
| Best viewed on desktop. | |

| ## Instructions for Editor3D UI | |
| - Use 'WASD' keys to move the camera. | |
| - Click on an object to select it. | |
| - Use the sliders to change the position, size, and orientation of the selected object. Sliders support click and drag for faster editing. | |
| - Use the 'Add Box', 'Delete', and 'Duplicate' buttons to add, delete, and duplicate objects. | |
| - Delete and Duplicate buttons work on the selected object. Duplicate creates a copy and selects it. | |
| - Use the 'Toggle Mode' to switch between "normal" and "depth" mode. Final image sent to the model should be in "depth" mode. | |
| - Use the 'Render' button to render the scene and send it to the model for generation. | |
| ### Lock style checkbox - Fixes the style of the latest generated image. | |
| This allows users to edit the 3D boxes without changing the style of the generated image. This is useful when the user is satisfied with the style/content of the generated image and wants to edit the 3D boxes without changing the overall essence of the scene. | |
| It can be used to create stop motion videos like those shown [here](https://shariqfarooq123.github.io/loose-control/). | |
