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.

🚀 Quick Start

Prerequisites

  • JDK 21 or newer

Build and Run

To launch the GUI viewer:

./gradlew run

To run tests:

./gradlew test

✨ Features

  • 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.

📂 Project Structure

  • 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.

🛠 Scripting Interface

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