pclod / unity-delaunay

Port of as3delaunay to C# for Unity

NOT MAINTAINED

The original code kept crashing Unity, revealed internal core bugs in Unity. I tried to get Unity corp to accept / fix these, but they refused, so ... I found a better library to work with.

Use Triangle.net, the open-source C# library that's higher performance with more features. It does delaunay and voronoi.

Fork of Unity-Delaunay

This fork exists to add:

• Issue-tracking (missing from master project)
• More interactivity in the demo project / add missing docs to source code

I hate forking projects - big waste of time - but with no issue-tracking on upstream, I really had no choice.

Current features

Upgrades compared to upstream:

• NOW PACKAGED AS A SINGLE .DLL FILE YOU CAN DRAG/DROP INTO UNITY
• Demo project lets you enable/disable rendering of individual features
• Helps you understand the definitions (undocumented in source)
• Helps you experiment with the data structures before embedding in your own projects
• Usage instructions!

Instructions

Running the Demo

• Open the "demo" folder in Unity as a new Project
• Open the "Demo" scene inside Unity (otherwise nothing will happen when you run)
• Select the "Extended demo" object
• Click the "re-generate" button to make a new random Voronoi
• in the Editor view you'll now see a coloured diagram of your data
• also you now have tickboxes to show/hide various features of the output data

Including in your own game/app

1. In the CSharpLibrary folder, there should be a subfolder: AS3DelaunayExtended/AS3DelaunayExtended/bin/Debug
2. ...which contains the DLL: AS3DelaunayExtended.dll
3. Drag/drop that DLL into your Unity3D project, and Unity will automatically load + add it
4. You can now use all the classes and features in your project
5. NB: this DLL does NOT include the Custom Editor classes (Unity requires two DLLs if you want that)
6. NB: this means you lose the custom buttons for "Re-generate Voronoi"; you can use the function via script/code only!

Unity-Delaunay

Voronoi diagrams, Delaunay triangulation, minimum spanning graphs, convex hull and more. Ported to C# for use in the Unity game engine from https://github.com/nodename/as3delaunay.

Features:

• Voronoi diagram
• Delaunay triangulation
• Convex hull
• Minimum spanning tree
• Onion
