# Delaunay Triangulation pattern maker



This project allows you to create beautiful high quality images featuring a nice pattern created from Delaunay triangulation and applying a flat surface shader. These images could be used for:



- Wallpapers

- Blog post headers

- Magazines

- Posters

- And more



The tool provides export to PNG and SVG formats. With SVG format you could create an image of virtually any size, even as big as a billboard. Go crazy with it!



## Show me some results!



Here are a few of most obvious uses for the tool:

![two devices](https://raw.github.com/msurguy/triangles/master/examples/two-devices.png)

![billboard](https://raw.github.com/msurguy/triangles/master/examples/billboard.png)



And I made a video on Youtube of the tool in action, creating 11 wallpapers in under 7 minutes:

You can also see some examples of the patterns made with this tool in this repository in the examples folder (the first one had text overlay added in Photoshop):

## Using



- To add a new light press Enter key on your keyboard or increase count manually via the slider.

- To "drop" or "pick up" the currently selected light, press Space bar.

- To change colors of the lights, change the ambient and diffuse color controls.

- To export as SVG select SVG in the "renderer" panel and then export the image via "Export big" button. Then navigate to "File -> Save as" in the browser's menu to save the resulting image to your computer.

## Building



Install Dependencies:



    npm install [email protected]



Build (cd into 'build' folder first):



    node build.js



## Inspiration



The iOS game called "[Monument Valley][monument]" by [ustwo][ustwo] served as an inspiration for this project. Specifically the simulation of the ocean in the game.



## Acknowledgments



The shader work was done by Matthew Wagerfield on his MIT-licensed [repository][repository].

## TODO



There are a few things that can be improved to make this tool even better.



- ~~Add varying depth of the vertices of the triangles~~ (Done as of 4/15/2014)

- ~~Add more color variation and presets~~ (Done as of 4/25/2014 with the randomizer functionality)

- Add text overlay and customizer for text



If you can do any of these things - feel free to make a pull request!
