Ripple Tank, webgl version
RippleGL is a ripple tank simulation that runs in the browser. It was originally written by me, Paul Falstad, as a Java Applet. Then Iain Sharp adapted one of my other applets, a circuit simulator, to run in the browser using GWT. So I used some of his code to build a similar port of the java ripple tank to GWT. In the process, I also converted the simulation code to WebGL, for much better performance.
For a hosted version of the application see http://www.falstad.com/ripple/
The tools you will need to build the project are:
This repository is a project folder for your Eclipse project space. Once you have a local copy you can then build and run in development mode or build for deployment. Running in super development mode is done by clicking on the "run" icon on the toolbar and choosing http://127.0.0.1:8888/Ripple.html from the "Development Mode" tab which appears. Building for deployment is done by selecting the project root node and using the GWT button on the Eclipse taskbar and choosing "GWT Compile Project...".
GWT will build its output in to the "war" directory. In the "war" directory the file "iframe.html" is loaded as an iFrame in to the spare space at the bottom of the right hand pannel. It can be used for branding etc.
The link for the full-page version of the application is now:
http://<your host>/<your path>/Ripple.html
Just for reference the files should look like this
-+ Directory containing the front page (eg "ripple") +- Ripple.html - full page version of application ++ ripple (directory) +- various files built by GWT +- examples (directory) +- setuplist.txt (index in to example directory)
You can link to the full page version of the application using the link shown above.
If you want to embed the application in another page then use an iframe with the src being the full-page version.
You can add query parameters to link to change the applications startup behaviour. The following are supported:
.../Ripple.html?rol=<string> // Load the example from the URL .../Ripple.html?startExample=<filename> // Loads the file named "filename" from the "examples" directory .../Ripple.html?colorScheme=rrggbb,rrggbb,... // 8 hex color specifications for walls, + waves, - waves, 0 waves, +,-,0 waves in media, sources
The Electron project allows web applications to be distributed as local executables for a variety of platforms. This repository contains the additional files needed to build Ripple as an Electron application.
The general approach to building an Electron application for a particular platform is documented here. The following instructions apply this approach to Ripple.
To build the Electron application:
Thanks to @Immortalin for the initial work in applying Electron to CircuitJS1, which was then applied to Ripple.
