You need a webcam to enjoy this blogpost to the fullest This post is a brief addendum of my previous post about Azoth. I was so excited about Azoth’s performance in my previous post that I didn’t take enough time to come up with a more practical example. Like I said last time, ByteArray operations [...]

Supercharge your ByteArray operations using Azoth
(edit: take a look at my next blogpost for more fun with Azoth !) I recently came across an interesting use of Adobe’s Alchemy technology. Basically what Alchemy allows you to do is run compiled c/c++ code inside of the ActionScript Virtual Machine. This in turn allows you to implement low-level optimizations that can lead [...]
Encoding a GIF from webcam snapshots with Flex Hero 4.5
As a Flash/Flex developer, I was very dissappointed when I found out Flash and Flex can’t handle GIF (Graphics Interchange Format) files. Untill I came across Thibault Imbert’s work ! He wrote an easy to use GIF Player & Encoder class in ActionScript 3. We’ll be creating a Flex application that uses Thibault Imbert’s classes [...]

Prerequisites: – an iOS device. – Flash professional CS5 – an iPhone dev. license/certificate that allows you to package flash and deploy on iOs.

Adding swipe gestures to your mobile Flex application

drawing a perfect circle with the curveTo function.
I’m guessing most of you already know what the graphics.curveTo function is. As the name suggests, it allows you to draw a curved line that starts at a certain point, bends towards a control point, and ends in an anchor point. The starting point of the curve can be defined in three ways: undefined: the [...]
the Monty Hall problem: A programmer’s approach
I’ve always enjoyed mindgames, but there was always one riddle that I just couldn’t wrap my head around. You may or may not have heard about the Monty Hall problem: Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a sportscar; behind the others, goats. You [...]
estimating the duration of a Sound Object while loading.
In case you never used the Sound class before, let me give you a brief introduction. The Sound class is found in the flash.media package and is used (hard not to be obvious here) for playing sounds. The constructor for the Sound class has 2 optional parameters: stream:URLRequest = new URLRequest(“url:String“); context:SoundLoaderContext = new SoundLoaderContext(“buffertime:Number” [...]

3D rotation at runtime with 2 lines of code
In the weeks before my workshop at Multi-mania (getting up to speed with native 3D) I spend a lot of time experimenting with some new api’s. One thing that I kinda needed from the start is a decent rotation class to rotate an object in 3D (at runtime). So I set off and create 2 [...]
