wave terrain input

hi

i've been working on a dynamic wave terrain synthesizer which uses video input for terraforming.

i thought you guys could give me some pointers...
what i'd like to do is create arrays from the brightness values of the X axis of a matrix, moving downwards. (a 600X400 matrix would then output 400 different arrays as fast as possible)

the arrays would be fed one by one into a buffer to be played back by a cycle~ object.

the MSP side of it is super simple. the jitter side on the other hand... i need your help!

thanks!
