Optimize bitmapData Post-Proccess effects (included source)

Hey I’m new to the forum but figured this was a good place to start looking for some help.

I’m working on a game engine that will let me do some cool visual effects but I find I lose alot of FPS on the perlinNoise and fading the alpha of the reflection.

I’m sure I’m not coding this as well as it could be. As I am new to all the bitmapData stuff.

Here is a link to it in action --> http://rybram.com/flashStuff/bitmapFilter.html


 
removed - updated version of it will be available on my site rybram.com
 

So yeh any feedback on how I could improve this would be awesome! Also if anyone has any questions on how any of this stuff works I’d be more than happy to share.

Cheers.
