The surface pattern is created in grasshopper from a jpg sourced, heightfield surface. The diameter of the circles are a factor of the z-depth of the resulting heightfield and can be parametrically controlled.

   Hi! this looks great!
   how did you make the depth from Jpeg file?

   June, use the “heightfield” command in rhino. It’s pretty crude – darker colors simply recede – but can be effective to simulate depth from an image.

   Thank you for the share this great grasshopper work!
   How did you paint light brown inside of plenty of circles on top picture?

   Pretty easy – just use the Make2D command in rhino, export as .AI, then open in illustrator and add a fill.
