Pixel Bender to Native Plugin

$

Hi!

 

I'm quite used to expressions, scripting, and pixel bender, but I don't know about programming (yet...).

 

I have a bunch of pixel bender plugins that I'd like to be native Plugins. And I don't really know how to start...

 

I figured out how to set my parameters and controls, compile into .aex.

But I still don't understand how to get my pixels coordinates, transform them (with a matrix or simple operations) and then render them...

 

for example, in pixel bender, I would have:

 

float2x2 myMatrix = some matrix value...

 

float2 pos = outCoord();

 

pos = pos*myMatrix;

 

dst = sampleLinear(src,pos);

 

can I do it, for example, in the skeleton file?

 

I saw the "put your interesting code here"... but don't know how to write that code!

 

If anyone can tell me, just on that example, it would be great!!

 

Thanx

 

PS: or is there somewhere an example of something similar to the Geometry effect?
