Here's a trick combining graphics filters with Google maps for some interesting effects. They don't necessarily make it easier to read the maps, nor do they have a lot of value, but they look interesting, and are fun to play with. I can't claim this idea as my own. I just randomly stumbled across this post on axismaps.com, and figured I'd throw together a Flex example showing how to do it.
Since diving back into PaperVision3D in my last post, I've been having some fun playing with 3D concepts. I forgot how cool 3D visualizations can be, but at the same time, they can get really confusing and really complicated very quickly. At the same time as they are getting complicated and confusing, they also start creating abstract shapes that are intriguing.
With all this talk about Astro, and PixelBender, it made me think more about graphics filters. So, I thought I'd revisit them. A few months back, I did a series on graphics tricks. This time, I'm sticking to the good old filters (not the shiny new ones in PixelBender), and decided to focus on displacement map filters. Basically, the displacement map filter displaces the pixels of a component, based on the bitmap data that is passed into the filter.

I've discussed graphics filters previously, and here's a trick to use them to extend the capabilities of basic Flex controls. In this example, graphics filters will be used to alter the appearance of a basic tree control. I've run into this scenario numerous times... How can you change the appearance of tree folder icons to imply meaning to the branches of the tree?

Here's the third installment of my mini-series on Flex graphics tricks. These do not only apply to Flex, they apply to Flash as well. My particular focus here is using graphics filters within a Flex application. Graphics filters allow you to perform bitmap-level effects on any DisplayObject... thus any object that can be displayed in Flex. Filters enable everything from blurs, glows, and dropshadows all the way to color processing, sharpening, and edge detection. This sounds very daunting, however they are really pretty easy to get started with.
