Mandelbrot (WebFX demo)

TARGET AUDIENCE

This app has been published for developers following the WebFX project, and is part of the project demos.


FOR NEW AUDIENCE

WebFX is a free, open-source cross-platform solution that can target 7 platforms (Web, Android, iOS, macOS, Linux, Windows & embed such as Raspberry Pi) from a single Java code base.
Underlying technologies: OpenJFX, Gluon & GWT.

For instance, you can visit the web version of this same app at https://mandelbrot.webfx.dev

Whatever the platform, the application source code is exactly the same (see the LINKS section below to access the source code of this demo).
The application is written in Java and uses the JavaFX API to build the user interface.
The Gluon toolchain (built on top of GraalVM) is used to compile the application Java code into a native app for all platforms except the Web (so this includes this Android version).
GWT is used to compile the Web version. It transpiles the Java code into an optimised JavaScript code.
As a result, all executables in all platforms offer optimized performances.


ABOUT THIS PARTICULAR DEMO

This demo is similar to the Ray tracer demo, but in addition it does take advantage of WebAssembly on the Web platform.

Like for the Ray tracer, the Mandelbrot demo shows an example of an app that doesn't block the UI despite a heavy CPU usage, and this on any platform (even on the Web).

While the application is doing computation, the UI is still reactive, you can even play the animation computed so far while it continues the computation in the background.

This is achieved by using the WebFX Worker API and WebAssembly API, which is translated to actual Web Workers for the web platform, and standard Java threads for other platforms.

When WebAssembly is supported (Web platform only), the computation is done using WebAssembly.
