Actionscript 3 Color Sampler Class

Actionscript Color Sampler

Yesterday, I published a video visualization experiment that used a color sampling engine to drive realtime data-driven abstractions of a video. I promised that I would release the color sampling class with some documentation and an example. Well, I was fortunately enough to have a chunk of time to do just that.

The color sampling class has been documented and gone through an optimization pass. Depending on the implementation of the sampler, performance can begin to get relatively shaky. Nonetheless, the video sampling was able to sample and spit out results at a fairly impressive pace.

Daily Delicious – Flash Performance and Memory Usage Tips

Posted on 2 March, 2007 at 1:06pm with 1 comment »

If you have not been to the Big Spaceship Blog yet, you should. They have all sorts of great tips and thoughts ripe for the taking. Their most recent article is the second post in a series of Flash performance tips. I was aware of a few, but others were completely new to me. Performance optimization may seem like a nerdy thing to some, but the process allow things to be done in Flash that otherwise would be too costly to the average processor or be a memory hog.

One of the pieces I especially enjoyed were links to resources on advanced collision detection. There has been some really good work in this area and I found is really helpful as my experience in that subject is extremely low. Really though, all the tips are very helpful and any Actionscripter should take a few minutes out of the day to read this article.
