jDistMesh is a Kotlin implementation of DistMesh – a simple generator of unstructured triangular meshes.

Originally developed as a Java port for a diploma thesis at CTU FEL, this version has been modernized to Kotlin and uses Gradle for build management.

• JDK 21 or newer

To launch the GUI viewer:

./gradlew run

To run tests:

./gradlew test

• 2D Mesh Generation: Pure Kotlin implementation of the DistMesh2D algorithm.
• Interactive Viewer: GUI for visualizing the triangulation process in real-time.
• Scripting Support: Ability to define mesh parameters (distance functions, edge length functions) using Kotlin Scripts (.main.kts).
• Delaunay Triangulation: Includes a custom 2D Delaunay implementation.

• src/main/kotlin: Core algorithm and GUI viewer.
• src/main/scripts: Example mesh definitions using Kotlin Script.
• src/main/matlab: Original MATLAB implementation for reference.

The application can execute external scripts to define complex geometries. Example scripts can be found in src/main/scripts/.

This project is a port of the original DistMesh by Per-Olof Persson and Gilbert Strang.
