Problems with grasshopper with ecotect input

I am trying to make a definition in grasshopper that is defined by points in a surface which can be matched on a large geometry with subdivided surface.

The material can be adjusted in terms of length and numbers on the surface which can in turn control the opening on the model. However I have no idea to make use the analysis from ecotect (attribute export?) or it's RGB color difference to re-divide the surface...

All I need is some samples or tutorial about linking the ecotect result to grasshopper which can inform the geometry to divide the surface with size differences... or anyway variations on the division...

It's quite rush as i have submission in 1 month... Thanks so much for the help!!!!
