Introducing a new ActionScript 3.0 SlideShow class

September 16th, 2008 : Nik Rowell

There’s just something about high quality photos fading in and out that always seem to take the feel of a site up a notch or two. Good examples are AMO’s very own Arizona Medical Group Management Association (AZMGMA) and Metro Atlantic Relocation Council (MARC). Both of these sites use a custom XML-driven Flash slide show, developed internally a couple of years ago. The ease of updates from using XML, and the aforementioned Flash flashy-ness make it a perfect solution for breathing life into an otherwise static page.

Make Some Perlin Noise! … a Flashbelt Follow-up

June 15th, 2008 : Nik Rowell

I had the opportunity to attend Flashbelt again this year. And it was awesome.

This year’s highlight was seeing Jared Tarbell speak again, who’s done amazing work in both Processing and Flash, and is a the co-founder of Etsy, an excellent marketplace for all things handmade! For those who have kids, or like wearing really small clothing, be sure to check out Orange Rhino for some sweet threads from our very own Jess Louwagie.

Jared’s session once again left me speechless. The work was refined and elegant, the music fitting, and the presentation seamless. What inspired me the most of about these speakers, however, was not just their work. It was how approachable they all were. And how apparent it was that their work was fueled by curiosity; a willingness to make mistakes and a stubbornness not to give up.

One of Jared’s pieces that caught my eye was a series renderings that used Perlin Noise to generate forms resembling an iris (of the eye, not the flower).

While analyzing some of his source code (special thanks to Jared for providing it), and listening to Eric Jordan’s mix, Indigo, it became apparent to me the potential of using BitmapData.perlinNoise() and BitmapData.getPixel() to achieve organic, pseudo-random results.

Papervision3D DOES NOT meet SoundData, unfortunately

April 17th, 2008 : Nik Rowell

I had every intention of using my recently released SoundData class in an experiment with Papervision3D. I got pretty far: Picked out a good Armin Van Buuren track, had an interesting animation started; just hadn’t added the code to respond to the sound spectrum.

Unfortunately, once I loose a little momentum on one of these side projects, the likelihood of a bigger, better experiment stealing it’s lunch money gets pretty high. I grew rather attached to this latest experiment and, despite it’s somewhat ‘incompleteness’, I wanted to share it anyways.

Special thanks to Seb Lee-Delisle for the inspiration and all his particle work on Papervision3D!

Here’s the experiment. Enjoy! (there are several colors and speeds… so if you don’t like what you get on the first pass… refresh the page ;)

Programmers Debate: _underscore private class properties?

April 2nd, 2008 : Nik Rowell

I tend to be a very thorough and detail-oriented person… at least I hope so (there are other words for it, but we’ll leave it at that). So naturally, when I’m writing code - whether it’s xhtml, CSS, ActionScript etc - I try and keep things neat, clean and easy to read. I indent like it’s going out of style, I strive for consistent naming conventions, and I use descriptive variable and function names.

SoundData: Facilitating Audio Visualization Experiments

March 31st, 2008 : Nik Rowell

In an effort to simplify audio visualization experiments with ActionScript 3.0, I’ve developed a SoundData class. The class’s main attraction is centered around the flash.media.SoundMixer.computeSpectrum() method, but it also provides additional control over playback, including startSound(), stopSound() and toggle() methods. The class also allows manipulation over volume and panning.

Fields of Purple - experiments with Papervision3D

March 29th, 2008 : Nik Rowell

I realize it’s been a while since my last flash experiment covering Audio Visualization with ActionScript… but fear not - I haven’t been taking a break. Very much the contrary :)

Flash Audio Visualization - See Music Without The Aid Of Drugs

January 30th, 2008 : Nicholas Longtin

Sound Visualization With Flash

My esteemed colleague Nik Rowell has graced these pages with some really cool Flash experiments in the past, which has inspired me to also explore the wonderful capabilities of ActionScript 3.

Audio visualization is a fun area to experiment in, as you can do some very interesting things with very little code. Nik showed us a unique way of looking at sound in this post. His code utilizes one mode of Flash’s sound compute spectrum method, which returns the raw sound wave data.

In my program I decided to use the Fourier transformation mode, which returns a set of calculations derived from the sound wave data. These calculations output a set of frequency numbers, starting with lows and ending with highs.

If your browser has Flash 9 installed click here to see a really cool song by Kate Havnevik brought to life with Flash. If you don’t see anything except the background right away, please be patient. On slower connections the sound may take a minute to load.

Audio Visualization with ActionScript 3.0

January 14th, 2008 : Nik Rowell

As many of you know, I’ve been spending a bit of my time exploring the cool features in ActionScript 3.0 - some new, some not. Lately, I’ve been intrigued by the SoundMixer class which has a special method, computeSpectrum(), that essentially takes a snapshot of the wave of a streaming sound (or an embeded sound, but I’m talkin’ 100% code here)…

The finer details quickly boil down to binary data, but the power of this is the potential to create audio-powered animations in Flash.

After a refresher in Trigonometry, some tortellini, and a late night (or early morning), I’m pleased to present latest ActionScript 3 experiment!

3D Glasses Optional: A New Twist on the ArcStone Logo

January 3rd, 2008 : Nik Rowell

I’ve done some more experimenting with the Papervision3D class library. This experiment uses a “Plane” object, the ArcStone logo for the plane’s “material” property, and a little bit of math to allow a full 360-degree view of the logo. The logo’s X and Y-axis rotation is determined by the mouse position.

Season’s Greetings from Outing, Minnesota - Virtual Postcard

December 31st, 2007 : Nik Rowell

I spent a good portion of my holiday weekend sifting through the documentation for Papervision3D (let this load, it’s worth the wait!). Papervision3D is robust, open source ActionScript class library that aims to simplify the process of creating and animating 3D objects and effects in Flash.
