About

This app computes the Delaunay triangulation of a set of points. Input points by tapping the screen or generate random sets to test computation speed. It's useful for interpolating data, like temperature readings between weather stations, by creating optimal triangulations.

What's New in Delaunay Triangulator

3.1.2

April 7, 2026

Minor updates and bug fixes

User reviews

Cool little visualizer

As someone with an interest in geometry this was fun to play with. A few feature suggestions to make it even better:

* Ability to drag or delete existing points
* Ability to create holes and multiple contours (perhaps with control over winding rules?)
* Import/export as SVG path

FAQ

What is Delaunay Triangulator used for?

Delaunay Triangulator computes the Delaunay triangulation of a set of points. This is useful for optimizing data interpolation, such as estimating temperatures between weather stations, by minimizing sliver triangles.

How do I input points into Delaunay Triangulator?

You can input points into Delaunay Triangulator simply by tapping on the screen. The app then computes the triangulation based on your tapped points.

Can Delaunay Triangulator generate its own points?

Yes, Delaunay Triangulator allows you to generate random point sets of different sizes. This feature helps in observing how computation time varies with the number of points.

What makes a triangulation 'optimal' in Delaunay Triangulator?

The app aims to create a triangulation that minimizes high aspect ratio triangles. This is considered optimal because it restricts region boundaries to be as close as possible to the input points, leading to more accurate interpolations.

Is Delaunay Triangulator available on Android?

Based on the provided data, Delaunay Triangulator is supported on iPhone, iPad, and iPod. Information regarding Android availability is not included.

How often is Delaunay Triangulator updated?

The latest version of Delaunay Triangulator is 3.1.2, last updated on April 7, 2026. This indicates a recent update, though the frequency of future updates is not specified.

What is the age rating for Delaunay Triangulator?

Delaunay Triangulator has an age rating of 4+. This suggests it is suitable for a wide audience, including children, with no mature content.

Does Delaunay Triangulator have ads?

No, Delaunay Triangulator does not contain advertisements. The app is free and does not feature any in-app purchases or ads.
