## What is VoronoiPlotter?

This app creates a Voronoi/Delaunay diagram from inputted generating points.
It is very suitable for study or education in area of science and technology.

The generating points can be inputted with a dedicated list view or a text editor, or imported as CSV or space separated text with copy and paste from the other app. 

An image picker is available to input coordinates on a image as a option.

On the "Graph" view, boundaries of Voronoi diagram and Delaunay diagram (triangular mesh), Voronoi cells, distances between generating points, or etc. can be drawn.
The image used in image picker can be displayed as a background image.

The created image can be exported as PNG/PDF/SVG/EPS file.
(PDF/SVG/EPS is option)

Geometry data of Voronoi/Delaunay diagram can be exported as CSV or tab separated text (option). Please refer app support page about the format.

The triangular mesh of Delaunay diagram can be used as a FEM mesh.

You can try all options with sample data.

## Key features

- Input generating points via list, text editor, or CSV import
