Grasshopper

algorithmic modeling for Rhino

Extrusions based on image sampler, need help! :)

Hi Guys,

So I am a bit of a grasshopper noob, but I am attempting to do the following and a bit lost on where to begin:

I have a black and white image. I would like to apply the image to a surface, then I guess divide the surface into a grid of squares and extrude those based on the darkness value of the corresponding area on the picture.

I then intend to 3d print that surface after I give it a thickness (I am fine with that part)

Cheers and thanks for any help!

Miles

Hi man, thanks for the link!

I tried it out however and am getting a problem. I have an integer connected to my srf grid set to 200. However I receive the error: * the u-count value is incorrect for this number of points*.

I tried changing the u expression to : *u + 1*

that did not work, picture is attached, any help would be much appreciated :)

effectively (u+1), but the integer should be the same at DivideSurface component
