HSSD: Habitat Synthetic Scenes Dataset |
|
================================== |
|
|
|
The [Habitat Synthetic Scenes Dataset (HSSD)](https://3dlg-hcvc.github.io/hssd/) is a human-authored 3D scene dataset that more closely mirrors real scenes than prior datasets. |
|
Our dataset represents real interiors and contains a diverse set of 211 scenes and more than 18000 models of real-world objects. |

|
|
|
This repository provides a Habitat consumption-ready compressed version of HSSD. |
|
See [this repository](https://huggingface.co/datasets/hssd/hssd-models) for corresponding uncompressed assets. |

|
|
- `hssd-hab.scene_dataset_config.json`: This SceneDataset config file aggregates the assets and metadata necessary to fully describe the set of stages, objects, and scenes constituting the dataset |
|
- `objects`: 3D models representing distinct objects that are used to compose scenes |
|
- `stages`: A stage in Habitat is the set of static mesh components which make up the backdrop of a scene (e.g. floor, walls, stairs, etc.) |
|
- `scenes`: A scene is a single 3D world composed of a static stage and a variable number of objects |

## Getting Started |
|
|
|
To load HSSD scenes into the Habitat simulator, you can start by installing [habitat-sim](https://github.com/facebookresearch/habitat-sim) using instructions specified [here](https://github.com/facebookresearch/habitat-sim#installation). |
|
|
|
Once installed, you can run the interactive Habitat viewer to load a scene: |
|
|
|
``` |
|
habitat-viewer --dataset /path/to/hssd-hab/hssd-hab.scene_dataset_config.json -- 102344280 |
|
# or ./build/viewer if compiling from source |
|
``` |
|
|
|
You can find more information about using the interactive viewer [here](https://github.com/facebookresearch/habitat-sim#testing:~:text=path/to/data/-,Interactive%20testing,-%3A%20Use%20the%20interactive). |
|
|
|
Habitat-Sim is typically used with [Habitat-Lab](https://github.com/facebookresearch/habitat-lab), a modular high-level library for end-to-end experiments in embodied AI. |
|
To define embodied AI tasks (e.g. navigation, instruction following, question answering), train agents, and benchmark their performance using standard metrics, you can download habitat-lab using the instructions provided [here](https://github.com/facebookresearch/habitat-lab#installation). |
