Dataset Viewer

The dataset could not be loaded because the splits use different data file formats, which is not supported. Read more about the splits configuration. Click for more details.

Couldn't infer the same data file format for all splits. Got {NamedSplit('train'): (None, {}), NamedSplit('test'): ('json', {})}

Error code:   FileFormatMismatchBetweenSplitsError

Ctrl-Room dataset introduced in "Ctrl-Room: Controllable Text-to-3D Room Meshes Generation with Layout Constraints"

paper | project page | code

This repository hosts the Ctrl-Room dataset, a collection of semantically annotated 3D scenes derived from the Structured3D dataset. 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 for each room, which can be used for training text-to-3D generative models.
