Dataset Summary

This dataset contains 14,202 high-quality texture images and HDRI environments from ambientcg.com. It includes a comprehensive collection of materials such as fabric, metal, wood, stone, concrete, nature elements, and HDRI skyboxes for 3D rendering and computer graphics applications. The original archives were downloaded, unpacked, and images were compressed using PNG optimization and JPEG quality compression (90%) to reduce file size while maintaining excellent visual quality.

Languages

The dataset is monolingual:

  • —English (en): Texture titles, descriptions, and tags are in English.

Dataset Structure

Data Fields

Each texture/HDRI in the dataset is accompanied by a JSON metadata file containing the following fields:

Individual asset metadata (in .tar files):

  • —tags: Array of strings representing material types, colors, environmental conditions, and descriptive terms associated with the asset
  • —technique: String describing the creation method (e.g., "Stitched HDR Panorama", "Photogrammetry", "Procedural")

Complete metadata (in metadata.jsonl.zst):

  • —id: String containing the unique identifier for the asset
  • —title: String containing the full title of the texture or HDRI
  • —tags: Array of strings representing material types, colors, environmental conditions, and descriptive terms associated with the asset
  • —technique: String describing the creation method with additional details (e.g., "Stitched HDR Panorama (horizon clearing)")
  • —download_url: String containing the original download URL from ambientcg.com

Data Splits

The dataset contains a single split:
