RIAs in HTML versus Flash
In an ideal world, my life would be spent tinkering with computational fluid dynamics, morphogenesis and other physics goodness in ActionScript and Flex, but sadly the rent has to be paid and the cats...

Gray Scott Reaction Diffusion using Pixel Bender
I recently used ActionScript Workers to simulate the Gray Scott reaction diffusion model. Now, while it was an interesting experiment with Workers, there was an obvious elephant in the room by the name...

Pixel Bender Gray Scott Revisited
I had a few hours spare this evening, so I thought I'd tweak yesterday's implementation of Gray Scott in Pixel Bender. I wanted to vary the Gray Scott parameters across space - with a graduation of...

Reaction Diffusion Explorer in Flex and Pixel Bender
Here's an end of year treat for any reaction diffusion geeks - it's an evolution of my last Pixel Bender based experiments, the Reaction Diffusion Explorer. The original Gray Scott engine has been...

False Colour Rendering with Pixel Bender
As part of my Reaction Diffusion Explorer, I wanted to add false colour rendering. I've done this in the past in ActionScript, but to render in real time, I need to implement it in Pixel Bender.The...

Apache Flex 4.9.0 - VectorCollection vs ArrayCollection Performance
I got Apache Flex 4.9.0 installed under FlashBuilder 4.7 today - not the easiest software installation ever, especially for somebody with a command line aversion like me. So most of my day has been...

Stage3D: Belousov–Zhabotinsky in AGAL
Sadly, it seems that Pixel Bender might be nearing the end of its life and being replaced by AGAL - Adobe Graphic Assembler Language. AGAL is a low level language designed specifically for creating...

More Stage3D: Gray Scott Reaction Diffusion Model in AGAL
Following on from last week's implementation of the Belousov Zhabotinsky reaction in AGAL, I made the next step and spent a snowy Sunday porting my Pixel Bender implementation of the Gray Scott model...

Stage3D and AGAL Reaction Diffusion Explorer
I'm excited to be able to post the first iteration of my Stage3D based Reaction Diffusion Explorer based on my AGAL Gray Scott shader. I dusted off my SoftSkin skin from a few years ago which gives the...

Reaction Diffusion Explorer - Stupid Little Bug Fixed!
I noticed this morning there was some odd behaviour in last night's release of my AGAL Reaction Diffusion Explorer: even when the two dV parameters were the same, its parameter gradient type still...

Exotic Morphogenesis: Willamowski–Rössler in Stage 3D & AGAL
My experiments with reaction diffusion simulations continue with an AGAL implementation of a slightly lesser known model: the Willamowski–Rössler equations. After some pottering on the internet, I...

Willamowski–Rössler: Stage3D Sampling Artefacts Fixed
In my previous implementation of the Willamowski–Rössler equations in AGAL and, indeed, in all my previous AGAL experiments (with one inexplicable exception: my first AGAL demo, Belousov Zhabotinksy),...

Stage3D & The Joys of Mipmapping
This evening, I locked myself away with a glass of Rioja determined to fix my Stage3D rendering woes once and all. Last night's efforts were so close, but I couldn't help feeling they could be tweaked...
View ArticleFlex and Pixel Bender Running in a Browser on an iPad? Easy!
I heard about Puffin Browser a while ago, but never got round to trying it. Puffin is an iOS browser that supports Flash content by executing it in the cloud. I'd assumed that it might be a little...

ActionScript Workers Now Work Under Chrome/PPAPI
I did a lot of tinkering with ActionScript Workers towards the end of last year. However, because I'd swapped out the PPAPI Flash Player in Google Chrome, I was oblivious to the fact that Workers...
