Processing.js is a JavaScript port of Processing, a programming language designed to write visualizations, images, and interactive content. It allows web browsers to display animations, visual applications, games and other graphical rich content without the need for a Java applet or Flash plugin. Processing.js was originally created to allow existing Processing developers and existing code to work unmodified on web. Processing.js uses JavaScript to render 2D and 3D content on the HTML canvas element, and is supported by browsers that have implemented this element (the latest versions of Mozilla Firefox, Opera, Internet Explorer, Safari and Google Chrome). The development of Processing.js was begun by John Resig and then picked up by students at Seneca College after its initial release in 2008. A team of students finished the port of Processing.js, fixing more than 900 bugs, shipping 12 releases, and creating a vibrant community in the process. The project was done through a partnership between the Mozilla Foundation and Seneca College, led by David Humphrey, Al MacDonald, and Corban Brook. The students continue to maintain the project today. ==Versions== * 1.4.0 The first version of Processing.js released in July 2010. * 1.4.1 This version resolved bugs present in prior version.The key events for focusing the mouse are handled with global keyEvent instructions which execute only when they receive focus. The versions are exclusively for development and production with API option.* Latest Upcoming Version(2.1) Processing.org will be launching a series of "alpha" releases as they prepare for 2.0. Alpha means unstable and that function names and APIs will continue to change (mostly in PShape, XML, and other new bits like JSON and Table). It might be a bit like driving a sports car but with the hood removed and one of the tires might occasionally blow out. There will be beta releases. After the alpha releases which restricts the APIs changing, but the bugs might still be around. You'll have a proper set of tires and a hood, but you might still need a coat of paint and a radio. Changes made in latest release: (2.1) * Libraries of OpenGL are built into core,no need of installing separate library. * Modified version of GSVideo library is used instead of java. * It allows one to choose two modes of platform for executing like Android or JavaScript by selecting from a drop down list in the main window. * Movie Maker class has been removed in that place an item tool which converts frames into video is added. * For reading XMl and loading separate loadXMl is added and getXXXAttribute is now changed to getXXX. * Exception handling is made as choice for advanced users. * A new Table class is added which made easy to deal with punctuation in spreadsheets like comma,delimiter. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Processing.js」の詳細全文を読む スポンサード リンク
