Overview
dart_earcut is a high-performance triangulation library for Dart, implementing the Earcut algorithm originally developed by Mapbox. It efficiently converts polygonal shapes into triangles, making it ideal for rendering complex geometries in 2D graphics and visualization applications. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, ensuring cross-platform consistency. Designed for speed and accuracy, it handles both simple and complex polygons with holes, providing reliable results for computational geometry tasks.
Use cases
- 2D game development
- Web-based map rendering
- Vector graphics processing
- Interactive data visualization
- Mesh generation for UI components
Key features
- Fast triangulation performance
- Supports polygons with holes
- Cross-platform compatibility
- Simple API for polygon input
- Accurate results for complex shapes
Suitable for
- Graphics developers
- GIS application creators
- UI/UX designers working with custom shapes
- Game engine integrators
- Data visualization engineers
Considerations
- Requires valid polygon input (non-intersecting edges)
- Not optimized for real-time dynamic updates
- Limited to 2D triangulation
- Does not handle self-intersecting polygons directly
- May need preprocessing for irregular inputs
