Polygon Triangulation Tool

Visualize, edit, and triangulate simple polygons interactively.

💡 What This App Does

This application performs simple polygon triangulation, transforming any valid polygon into a set of triangles by connecting non-adjacent vertices.

You can paste your coordinates, preview the polygon, adjust points interactively, and finally generate a triangulation diagram — all inside your browser.

📌 Input Guidelines

✔ Valid Input

A list of coordinates forming a closed loop with no self-intersections.

Example:
(x1 y1), (x2 y2), ..., (xn yn)

✘ Invalid Input

Polygons where edges cross, or where the order of coordinates does not form a closed boundary.

⚙ How It Works

1. Paste or enter the polygon coordinates.

2. Visualize and drag vertices to adjust the shape.

3. Submit the polygon for triangulation.

4. The system automatically generates the triangulated mesh.

5. View, compare, and analyze the output triangles.
