thanks pixelero! I just did my first PixelBender filter, can be seen here

@oyd11 : I might try that some day, I’ve just recently done some first studies with generating Sound with Flash 10.

@JP DeVries :
yes, it’s sometimes %, sometimes mod, see http://en.wikipedia.org/wiki/Modulo_operation

I think you’ll info in Menu:Help/Pixel Bender Specification in the toolkit, on the last pages of that pdf.

btw and generally, one thing sometimes causing extra trouble is that different languages have different practicies when it comes to the sign of a modulo operation with negative values: see http://en.wikipedia.org/wiki/Modulo_operation , second table on the right

Figured out the modulo question. This worked
float xr = float(5);
float yr = float(7);
float qer = mod(xr,yr);

Anyone know of a full list of built in PixelBuilder methods…I haven’t found any such thing from Adobe

Are you doing modulos division using ActionScript or from within PixelBinder? I’m having trouble doing simple modulo division in PixelBender getting ERROR: (line 35): ‘%’ : syntax error parse error

Cool man, the modulu-waves is real similiar to what we call in (musical) Analogue-oscillators “Hard-Sync”,
The 2d example is real cool. attach an oscillator man!

I’d love to see the pixel bender code for the random tile effect — can you link to it?

Awesome, well presented, many thanks.
