A JavaScript library for constructive solid geometry (CSG) operations on 3D meshes using BSP trees.
csg.js is a JavaScript library that implements constructive solid geometry (CSG) operations on 3D meshes using binary space partitioning (BSP) trees. It enables developers to perform Boolean operations like union, subtraction, and intersection to combine or modify 3D solids programmatically. The library handles complex edge cases, such as overlapping coplanar polygons, ensuring robust geometric computations.
Developers and researchers working with 3D graphics, computational geometry, or web-based 3D modeling tools who need to perform solid modeling operations in JavaScript.
csg.js offers a clean, concise, and well-documented implementation of CSG algorithms, making it both a practical library for 3D mesh manipulation and an educational resource for understanding BSP trees and Boolean operations in geometry.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses binary space partitioning trees for efficient and robust CSG operations, with clear algorithmic logic documented in the README.
Correctly manages edge cases involving overlapping coplanar polygons in both solids, ensuring accurate Boolean operations as highlighted in the demos.
Provides intuitive methods like clipTo() and invert(), making it straightforward to implement union, subtraction, and intersection with minimal code.
Serves as a concise reference implementation with well-commented code and Docco-generated documentation, ideal for learning CSG and BSP algorithms.
Lacks built-in support for importing or exporting common 3D file formats, requiring additional coding effort to integrate with other tools.
The BSP tree approach can be memory-intensive and slow for large or complex meshes, as noted in its lightweight, unoptimized design.
Does not directly work with popular 3D frameworks like Three.js, necessitating custom bridging code for practical web applications.
