On Chrome 5 / FP 10,1,53,64 Debug :
Processing time : 2-4s
Memory : ~10Mo
CPU usage : 5-10 % on a Intel Core2 Quad 2.83GHz

It’s very nice stuff ! I’m looking for some time to implements new GUI experiences on the Web, and i would use 3D (and other good stuff like voice recognition). But at this time, existing technologies (like PV3D) are too heavy…

So I’m very exciting to try Minko ! Hope something will be out soon !

@Cardin Thank you for your comment and your benchmark!

When dealing with large sets of pixels/numbers, Pixel Bender is the king. The best way to be verify that would be to redo the sample kernel I give in the post using the Flash bitmap API only. I’m pretty sure the difference will be huge! If I have some time I’ll try to put some numbers on “huge”

About multi-threading: it is not enabled if the kernel does not run asynchronously. Which is the case here. And as you can see, the performances are still good. Actually it runs pretty well even on an Atom @ 1.6Ghz notebook (Asus eeePC 901).

Another thing to take into account is how PB kernels are portable and distributables. It is a lot easier than releasing some random class with a poor doc. Here you can have everything in one file, with standards ways to handle input/outputs.

The problem would be the PB Toolkit itself: it’s not easy to work on this kind of shaders in the toolkit and we have to run them inside of Flash to make sure everything is OK. Sadly, a lot of features are not supported in the Flash player but it still possible to handle a large variety of effects.

It runs 3 – 5ms on mine, Firefox Flash 10.1 4-thread 2.26GHz. I’m interested in finding out more about PixelBender for bitmap effects in my project, but there’s just so little written about it regarding stability and portability.

Is PixelBender truly run-everywhere? I’ve read that unless the target audience have multi-core processors, PixelBender is not worth trying out. There’s also issues regarding the PixelBender Toolkit and what Flash displays. What are your opinions? Thanks in advance.
