JGraphV

A Java library for Graph Visualization that runs on Android, Web, and Desktop. JGraphV is powered by OpenGL. It is designed to be preformant on graphs with thounds of nodes while supporting panning and zooming to floating point precision.

Sample graphs

Web/mobile web demos.

How it works

A platform API for all platforms is specified in JGraphVCore project under com.github.rma350.jgraphv.core.portable. Each platform must provide a common API to OpenGL through GL.java (an intersection of GLES and WebGL), basic linear algebra, native arrays, and logging. The JGraphVCore project builds on this platform API to provide basic tools for building graphs, rendering them with OpenGL, viewing through an orthographic camera, and responding to input.

There are three additional projects JGraphVAndroid, JGraphVDesktop and JGraphVWeb, that provide implementations of the platform API from JGraphVCore and contain minimal runnable applications using the engine.

Developer set up

  • Make sure you have the Java 7 JDK installed
  • Install a recent version of eclipse (works with Juno, newer tends to be better)
  • Install the android eclipse plugin (see http://developer.android.com/sdk/installing/installing-adt.html)
  • Install the GWT eclipse plugin (http://www.gwtproject.org/usingeclipse.html)
  • git clone anywhere on your local machine
  • Create a workspace anywhere on your local machine
  • From eclipse in your new workspace: File->Import->General->Existing Projects into Workspace. Under Select root directory click Browse, then navigate to to [location where you git-cloned]/jgraphv/. Under the Projects box there should be 4 projects in a list all checked, JGraphVAndroid, JGraphVCore, JGraphVDesktop and JGraphVWeb. Click Finish.

If all is well, then everything should just build in eclipse. Cross platform development is hard! If you don't care about web or android, you can skip installing their eclipse plugins and just not import these projects.

Run locally

  • Android: plug your android device (with developer options enabled) into your computer. From eclipse, right on JGraphVAndroid select Run As -> Android Application.
  • Desktop: Right click on JGraphVDesktop->src/com/github/rma350/jgraphv/desktop/Main.java and select Run As -> Java Application.
  • Web: Right click on the JGraphVWeb project and select Google->GWT Compile. Select com.github.rma350.jgraphv.web.JGraphVWeb.java as the entry point module, the Log level to Info, and the Output style to Pretty. Click Compile. You can then visit the local file from your web browser JGraphVWeb/war/JGraphVWebDemo.html.
