Sand3D

Overview

Sand3D is presented as an open-source 3D library written as code. The dataset contains 3D objects created with Sand3D, an LLM-friendly language, and each object is a Python program describing parts, holes, positions, and materials. The collection also includes mechanical CAD parts whose dimensions are program parameters, plus meshes for Blender, three.js, and glTF engines.

Key Features

• 3D objects written as code in Sand3D, an LLM-friendly language.
• One Python program per object, describing part shape, holes, position, and material.
• Open-source dataset and library available through Hugging Face and GitHub.
• Mechanical CAD parts with dimensions expressed as program parameters.
• Meshes ready for Blender, three.js, and any glTF engine.
• Programs written part by part so people can read them and LLMs can learn from them.

Use Cases

• Learning 3D modeling through readable, part-by-part code examples.
• Building 3D applications or experiments from parametric object programs.
• Rendering object meshes in Blender, three.js, or glTF-based engines.
• Using mechanical CAD part programs with adjustable dimensions.

Getting Started

• Download the dataset from Hugging Face or access the Sand3D library on GitHub.

Before You Adopt

• License: Apache-2.0. Review its terms before using, modifying, or distributing the project.
• Meshes are intended for external 3D tools such as Blender, three.js, or glTF-compatible engines.
• Object programs are Python files that import the sky3d library.
