# Ctrl-Room dataset introduced in "Ctrl-Room: Controllable Text-to-3D Room Meshes Generation with Layout Constraints" 
[paper](https://arxiv.org/abs/2310.03602) | [project page](https://fangchuan.github.io/ctrl-room.github.io/) | [code](https://github.com/fangchuan/Ctrl-Room)

This repository hosts the Ctrl-Room dataset, a collection of semantically annotated 3D scenes derived from the [Structured3D dataset](https://structured3d-dataset.org/). It contains 11,986 filtered rooms, including 4,961 bedrooms, 3,039 living rooms, 1,848 kitchens, 1,500 bathrooms, and 638 studies.
Additionally, we also provide the scene descriptions following the format in [SceneFormer](https://arxiv.org/abs/2012.09793) for each room, which can be used for training text-to-3D generative models.
