Dat.GUI. Dat-gui - Simple UI for Demos. Dat.gui is a GUI widget for your demos. It provide way for the user to set parameters of the demo to play with it. It is simple to code, yet cool and minimalist on the screen. It is the blue vuemeters on the screenshot below. This post is a presentation of the library. How to include it Simply include the library file in your page. How to use it First initialize the object itself. Here is the visual result on the right. Lets configure it and add some variables First we need to store the values of the variables, lets call that params.
Let add a variable name interation to the widget. It will add a line in the GUI widget. dat.gui will see params.iteration is a Number and thus guess you want to display a slider for it. Lets Custom it Some More You may be easy be notified of user changes with callbacks. onFinishChange is triggered once the value is changed. You can customize further if needed. You can set up min/max limits and steps. Conclusion. Dat-gui - A lightweight controller library for JavaScript.
A lightweight graphical user interface for changing variables in JavaScript. Get started with dat.GUI by reading the tutorial at Packaged Builds The easiest way to use dat.GUI in your code is by using the built source at build/dat.gui.min.js. These built JavaScript files bundle all the necessary dependencies to run dat.GUI.
In your head tag, include the following code: Using dat.GUI with require.js Internally, dat.GUI uses require.js to handle dependency management. Then, in path/to/main.js: require([ 'path/to/gui/module/GUI'], function(GUI) { // No namespace necessary var gui = new GUI(); Directory Contents build: Concatenated source code. src: Modular code in require.js format. Building your own dat.GUI In the terminal, enter the following: $ cd utils$ node build_gui.js This will create a namespaced, unminified build of dat.GUI at build/dat.gui.js Change log Migrated from GitHub to Google Code.
Thanks. Raphaël—JavaScript Library. Web-Drawing Throwdown: Paper.js Vs. Processing.js Vs. Raphael. Advertisement Before drawing anything in a browser, ask yourself three questions: Do you need to support older browsers? If the answer is yes, then your only choice is Raphaël. It handles browsers all the way back to IE 7 and Firefox 3. Raphaël even has some support for IE 6, although some of its underlying technology cannot be implemented there.Do you need to support Android? Paper.js, Processing.js and Raphaël are the leading libraries for drawing on the Web right now.
Choosing the right framework will determine the success of your project. All of the code in this article is open source and can be run on the demo page that accompanies this article. Overview It’s all JavaScript once the page runs, but the frameworks take different paths to get there. PaperScript is a JavaScript extension that makes it possible to write scripts that don’t pollute the global namespace. Processing.js is based on a framework named Processing, which runs in the Java Virtual Machine. Getting Started Paper.js: (al) Paper.js — Paper.js. Processing.js. OpenProcessing - Share your sketches! iProcessing. Getting Started with Processing.js.
Recently John Resig released Processing.js. Its a pretty interesting project, which allows Processing code to be run in the browser. This article is a quick look at why it is worth checking out, and ends with a tutorial explaining how to get started. Why Does Processing.js Matter? I see (at least1) two reasons why translating Processing.js is important. The first is that Processing's philosophy and syntax have never felt like a good match. Downloads Processing.js is pretty easy to get up and running with, but first we have to download a few files. First, you will need to grab a copy of processing.js. Setting Up Now that we have the files we need, we'll need to throw together a hasty development environment. Next, copy or move the processing.js file you downloaded into the directory you just created.
Third, in that same folder, create an empty file called init.js. Now all we have left is to create is a simple html file. Using Processing.js So, lets put together the html template. Wrapup. Processing.js. Demos below! As a sort-of reverse birthday present I’ve decided to release one of my largest projects, in recent memory.
This is the project that I’ve been alluding to for quite some time now: I’ve ported the Processing visualization language to JavaScript, using the Canvas element. I’ve been working on this project, off-and-on now, for the past 7 months – it’s been a fun, and quite rewarding, challenge. The full scope of the project can be broken down into two portions: The Processing Language The first portion of the project was writing a parser to dynamically convert code written in the Processing language, to JavaScript. It works “fairly well” (in that it’s able to handle anything that the processing.org web site throws at it) but I’m sure its total scope is limited (until a proper parser is involved).
The language includes a number of interesting aspects, many of which are covered in the basic demos. The Processing API The second portion of the project is the full 2d Processing API. 10 Impressive JavaScript Animation Frameworks.
