This is the second part of a series on using Pixel Bender to create effects in Flex. In this part I’ll go through making a simple filter in Pixel Bender that can be used to animate an effect in a similar way to the last post.
You can get hold of a copy of the Pixel Bender toolkit here and also get hold of a lot of good reading material to get started using it.

This is the first of a two part series on using Pixel Bender filters in Flex effects. I’ve recently started to spend a bit of time with Pixel Bender and have found it to be a good tool for creating interesting effects and transitions in Flex. Even if you don’t write any yourself, there are plenty available to use at the Pixel Bender Exchange
In this first part I’ll cover an example of making an Effect and EffectInstance that extend the Flex framework and also use a Pixel Bender filter to achieve the effect. In the second part I’ll cover writing a Pixel Bender filter to use with a custom effect.
I won’t go over embedding and instantiating a filter as a Shader; this is well documented here. There is also a good example of animating a Pixel Bender filter here.
