i have two definitions: on one side a definition that shows displacing a mesh with an image in GH, and on the other side the creation of a rectangle components.

so my question to you is, how can i bring them together?
would be nice to get any kind of suggestions.

thank you.

Hi RWNB, is it an option to use a SrfGrid instead of a Mesh (sorry I'm not much of a mesher), and then MapSrf?

dear pieter,

i want to know how to manipulate objects with a bitmap.

if you can do this with a srfGrid, why not. i want to see it. (:

dear pieter,

thank you, an interesting approach. the curves are now on ..

but the faces are gone! would look forward to a release. (:

Maybe you can just create the curves, map these to the surface, and then create the 4Ptsurfaces. They won't be planar though, if that's what you're after...

dear systemik,

i have tried to build your example, but with little success.
what have you typed in the expression editor of the input parameters U and V?

Ahah !

Hint:

Also, you connected P to image sampler instead of UV. That can work if your image has same dimensions as the surface though. Or if you redefine the domains in the imagesampler component.
