AJAX WEB SCRIPTING

Creating the illusion of depth in images was first invented 1838 by Sir Charles Wheatstone. It is today still a great experience to
view high quality large format images with depth perception, exceptionally of virtual objects like reconstructions of the past or
building projects.

High quality presentation of computer graphics is provided by projection onto a transparent screen surface from behind. Image
separation can be easily performed by polarisation filters in front of the projection lenses. It is necessary that the beholders carry
polarized glasses. Interactive viewing in this context means, that the observer is able to select image pairs from the database, can
zoom in and out, select the display details and sets the zero parallax to an arbitrary position. The selection must be simultaneously
transferred to the second image of the stereoscopic pair.

While each data projector is driven by its own computer, a PDA (personal digital assistant) is recommended to receive the
instructions from the presenter or viewer. That network configuration requires amongst other software tools Bluetooth, to connect
the PDA to a local computer network, and ActiveSync, to hold a continuous connection between the PDA and the host computer.
Furthermore a Web server with PHP (hypertext pre processor) extension is running. Web browsers are acting as clients on both
computers and the PDA as well.

The challenge is now to write an application software that provides an interface on the PDA to set the adjustments and pushes the
image information to the graphic cards of the host and the slave computer. To minimize the effort in software development, open
source software components are largely applied to this system. We take advantages from Mozilla Firefox Web browser and Apache
Web server.

free ebook and tutorial - AJAX and Connection Manager

As far as web interface design techniques are concerned, AJAX is definitely the way to go. So what JavaScript library worth its salt these days wouldn't want to include a component dedicated to this extremely useful and versatile method of client/server communication?
The Connection Manager utility is by no means the smallest, most light-weight component included with the YUI, but it's certainly not the largest either, yet it packs so much functionality into just 12Kb (for the–min version).

free ebook and tutorial - 4D Ajax Framework 1.2 Addendum

The 4D Ajax Framework developers have heeded the requests of many 4D developers to make version 1.2 a much more customizable and effi- cient product than version 1.1. New developer hooks are introduced, a newer and more robust callback schema is implemented, and the framework itself went through a diet of sorts by reducing unneeded resources for the purpose of optimizing speed and performance. These changes, along with the numerous bug fixes, have made the 4D Ajax Framework an impressively improved build that 4D developers are sure to love.

free ebook and tutorial - The security risks of AJAX

The term web 2.0 was coined by O’Reilly Media following a number of conferences that it hosted in 2004. The popular media latched onto the concept and turned it into a popular phrase that has become synonymous with a new breed of website. Web 2.0 sites typically bring user collaboration to the foreground and offer interactivity closer to that of a desktop application.

Welcome to the world of Ajax, the technology that lets Web software act like COPYRIGHTED MATERIAL desktop software. One of the biggest problems with traditional Web applications is that they have that ìWebî feel ó you have to keep clicking buttons to move from page to page, and watch the screen flicker as your browser loads a new Web page. Ajax is here to take care of that issue, because it enables you grab data from the server without reloading new pages into the browser.
