Grasshopper

algorithmic modeling for Rhino

I am creating a surface from a script that generates a surface grid from an image, however its a square grid. I would very much like to make this grid perpendicular to the way it currently bakes and follow a curve. Where do I start?

Thanks,

John

Michael Pryor made some pretty good definitions on this issue. Take a look:

That is great, thank you. I do not understand what I need to input for the geometry though.

Ripple source is point.
Ripple surface is just a plain surface.

Ripple source is point  can be any geometry :)

Thank you Michael.
I learned something too.

I agree.
My dog pulls me to the ground each time some handsome female dog is passing by.
