# HSM

## Overview
This repository contains the support region dataset introduced in the paper [HSM: Hierarchical Scene Motifs for Multi-Scale Indoor Scene Generation](https://arxiv.org/abs/2503.16848). For the project page, see [here](https://3dlg-hcvc.github.io/hsm/).

It includes manually annotated support regions for 3D furniture meshes from the [Habitat Synthetic Scenes Dataset (HSSD)](https://huggingface.co/datasets/hssd/hssd-models), as well as HSM-generated scenes for the [SceneEval-500](https://github.com/3dlg-hcvc/SceneEval/) benchmark used in the paper.

### Note on Dataset
The dataset contains 81 objects from HSSD. This release excludes 19 non-public assets that were present in internal datasets.
