Creating Surface Patterns Using Bump Maps Created in Photoshop as an input parameter in Rhino’s Grasshopper
Tuesday, November 18, 2008 3:28This tutorial describes how to create patterns on a surface using bump map images from Photoshop as control surfaces for the patterns. First, bump maps are created in Photoshop and imported into Rhino using the HeightField command. These are then referenced in the grasshopper file to control the size of the circles that make up the pattern. This is a technique that can be used to create patterns and super graphics quickly.
Note: there are a few audio problems on this video from my iphone being too close to the mic. sorry about that.
High quality video…
Low quality video…
UPDATE:
I recieved an email question on this post asking if it is possible to make the circles into hexagons. To do this I replaced the circle component at the end of the definition with a polygon componet. I set the number of sides of the polygon to six and that’s it. See the screenshot below for a visual explanation.

HI
Thanks for your wonderful tutorial!
What should I do if I want to use other kind of geometry which I made instead of circle or polygon which are made by grasshopper commands?
thanks

First: Thanks for a great tutorials… cant find them much for Grasshopper, especially done so studiously.
Question would be concerning the BRep CP function. As my surface is quite wavy, shortest distances are not simply projected from the bounding box surface to the Rhino shape… it congregate on the highest points. I would like to use lines which are in your example all parallel and perpendicular to the b.box surface.
Hope i made my problem clear. Thanks!

Thanks a lot for the video and descriptions, they’re very helpful.
I have the same question as some of the people above.
What should I do if I want to use other kind of geometry or even 3D geometry which I made instead of circle or polygon which are made by grasshopper commands?
Thanks
Regards,
Rosanna

Hi. tnxs for tut! How w can make something like this but with hexagons connected to one wire?
