New tutorial on Flash QuickTime export

As promised, I just finished uploading a new tutorial that shows you how to export ActionScript-based animations from Flash as QuickTime video as well as how to composite them in After Effects. This work flow allows you to create some really cool motion graphics that would be extremely hard to do without using Flash. Below is the finished product from the tutorial. The music is by HECQ, who works a lot with the Ronin. Check out the [...]

Acrobat animation with Fermat spiral

This is another little experiment I whipped up using Fermat’s spiral formula. It takes the the Acrobat logo and uses it to create some flower effects. Click on the image below to download a ZIP file including the FLA and SWF file. It chugs a little in the browser so it’s better to view it in the standalone player.

Flash Mathographics


While I was in Singapore I found a cool book that talks about various Math graphics theories called Mathographics. It also contains sample code written in BASIC. On the flight home I started translating some of these into AS3. The only bad part about the book is that the author leaves a lot of the work to you when it comes to trying to reproduce his graphics. Maybe I’m just spoiled by Flash books where you [...]

My first Pixel Bender filter (SquarePattern)

Today I spent a few hours getting up to speed with Pixel Bender. It definitely has a steep learning curve but it is well worth the effort. Below you can check out my first creation called SquarePattern for lack of a better word. This filter essentially samples the current pixel as well as a different pixel and averages them out. Which pixel is dependent on the amount parameter. The result is a kind of crosshatch effect.

I was actually [...]

ActionScript 3 Wedge Drawing Class

Here is another class that I wrote thanks to this old tutorial. This is similar to the Arc class except that it draws wedges instead. These are great for doing lightweight charting stuff. You can get the code at my Google Code repository. The example below rapidly animates new wedge shapes creating a cool effect. You can click on the image below to check it out.

Below is the source code for [...]
