...thanks for listing my shaders too, John. For my taste, people are a bit too reserved with developing Pixel Bender shaders. I really would like to see more of that stuff coming up in the future. For my part, I just released another shader-snippet on Adobe´s PB-Exchange: Deformer. -frank [Nice! It runs beautifully inside Photoshop. --J.]

I believe John may have been referring to Petri's TubeView filter. It's pretty cool. Check it out at: TubeView in Labs or TubeView in Exchange

… and from me also thanks for the mention John.
About my tunnel demo, Yes, Mr.doob’s right: my tunnel-demo uses drawTriangles, not pb
- nevertheless I did spend some plenty of thoughts on how to do that with pb, specially having the tunnel to bend would have been a bit more challenging …
Anyway, Glad you liked it !

Thanks for the mention John.
But, I though Petri Leskinen’s Tunnel was mainly using Flash10 drawTriangle and not using Shaders? I’ll have to check the code again.
[You would know infinitely better than I would! Sorry if I've confused the issues. I know that Petri is doing a bunch of PB work and has posted other cool PB examples on the page. --J.]

Hey John,
Is ‘silly fast’ a technical term on the Photoshop team? ;-)
I’ll point out that some of the same GPU goodness is also been applied to the After Effects product.

Interesting news! Will PixelBender filters running through the Photoshop CS4 plugin be able to present an interface (sliders?) to the user, and can these settings be recorded in actions and (by extension) in smart filters?
[Yes, and I believe yes. --J.]
Simon
PS – Although I’m not expecting it, it would be great if a PixelBender filter could determine the current color space – or ask for the RGB data to be delivered in a particular color space.

Pixel Bender won’t be supported in the box in the next version of Photoshop
Just to clarify: Does that mean that there won’t be any GPU acceleration for the regular filters in Photoshop CS4 and the GPU enhancements are basically limited to the rendering pipeline?
Peter
[That's correct. It's an evolution, not an all-out overnight change. --J.]

Good demo! Glad the PS World clip was made available for show & tell.
Being able bend those pixels any which way -on the fly- was amazing to see.
