After the overwhelming response of posting the sources of 300.000 pixels with Alchemy and Pixelbender, I thought it would be nice to post some more from my session at FITC Amsterdam.

First let's take a look at what people have done in response of the previous sources.

Yonatan Offek - Sierpinski Particles

Peter Nitsch - Alchemy Particles

David Lenaerts - Smoke, Milk and Ink

Dennis Ippel - Incredibly fast Plasma

Joa Ebert - Massive amounts of 3D particles without Alchemy and Pixelbender

All the work in that list is incredible, but for this post, I'm most interested in the last 2. Joa's work on getting AS3 up to speed with my Alchemy demo (Joa's demo is actually faster then the Alchemy version on my machine) is incredible. And it also proves the one thing I tried to convey in my blog post Adobe Alchemy, is it ActionScript Heresy ?.

Pushing around +300.000 3D particles, realtime, on screen, using Flash ? No problem, if you are using Adobe Alchemy & PixelBender to compile and run your code!

During my session "professionally pushing pixels" at FITC Amsterdam this year, amongst other things, I talked about how to best utilize parts of the Flash Player to get top performance. This is one of the examples I showed. What you are seeing in this example, is +300.000 particles being 3D transformed, projected and draw to 2D. And it does so at quite a good framerate (well, it'll depend on your machine too).

So, how do we achieve this ? The answer is a combination of PixelBender and Alchemy.

It's been silent here. Next to tripping to Tokyo to speak at Adobe MAX in Januari and doing some small jobs, I'm doing a very, very cool Flash 10 Project utilizing the upcoming Papervision for Flash 10. For some optimization parts I've been looking into using Alchemy as an easy way to write optimized bytecode. As opposed to what some people took from my previous post on Alchemy, I don't hate Alchemy. My point there was that if Alchemy can perform that well, so should ActionScript be able to, with the standard compiler.
