This is an interesting post. It is similar to moving from OpenGL ES 1.1 to OpenGL ES 2.0, where things begin to get moved onto shaders for efficiency and flexibilibility. I intend to pick through and read the follow up posts. Thanks.

just discovered Your blog, nice and useful stuff as far i saw, all thumbs up!!
Let me ask You just a quick question, as You seem to have the experience...
I heard it (somewhere) that the so called "bottleneck" of pixelBender is the "passing to" phase, getting the data into it.
Any words on this issue/topic ?
I assume that it depends on the calculus i'm up to...
On the other side of the balance is the multi-threadedness of the technology (is a great PLUS too), and the (not-so-far-future) hardware acceleration.

cheers.

why did you fix the length of vector after the shader job ?

job.start( true );
output.fixed = true;
