This definition takes any curved surface and populates it with a gradient of circles. The gradient is driven by a pixel sampling of any given image. For best effects, the surface size in inches should equal the image size in pixels. The definition also allows for the circles to be projected back onto the input surface in order to trim out the pattern from the existing surface, allowing for a perforated texture representing the given image.

Hello Sean:

Do you know how to keep the holes the same size only varying the quantity of holes per gray scale?

Thanks in advance.

Can't really help without knowing the error message.  You may be running an older version of grasshopper. (I built this in 08.0061  with rhino 4.0 sr9)  maybe try downloading the latest build?

Hey, this looks great, but I can't open your file...I get an error message, any ideas?
