# 3DCoMPaT200 Dataset

The 3DCoMPaT200 dataset is a comprehensive collection of 3D objects with compositional part annotations. This repository contains various formats and versions of the dataset organized for different use cases.

## 📁 Directory Structure

### 2D Folder
Contains train, validation, and test data in tar format for 10 compositions:
- Training set
- Validation set
- Test set

Each file contains 2D representations of the objects with their corresponding compositional part annotations.

### HDF5 Folder
Contains point cloud data in HDF5 format with 2048 points per shape:
- Single composition datasets (train/val/test)
- 10 composition datasets (train/val/test)

The HDF5 files are optimized for efficient loading and processing of point cloud data.

### Challenge Folder
Contains grounding prompts used for the Grounded Segmentation Challenge. These prompts are designed to evaluate models' ability to perform semantic segmentation based on natural language descriptions.

### Compat200.zip
Contains the original 3D object files in GLTF format:
- Training set objects
- Validation set objects
Note: Test set objects are not included in this file.

## 🔍 Dataset Details
- Number of points per shape: 2048
- Number of compositions: 1 and 10 variants
- File formats: TAR, HDF5, GLTF
