I’m trying to create stone work for a model of the Kincaid building (image) in Thurmond, WV. One of the attached images shows the Kincaid building and the other shows where I am not. I populated a box with 25 or so random points and then made a patch to the base rectangle. This creates a suitable surface, but it is smooth. Cut stone has a series of fracture planes. I’m trying to generate a series of fracture planes that comes close to matching that patch surface. I’ve tried slope analysis, combining the original point mesh with the patch mesh, and both didn’t work - at least the way I tried. Eventually the result will be fed to a laser engraver that is driven by the grayscale of the image. The grayscale of a photo of a stone face is the shadow generated by he lighting. What I want is a grayscale based on the distance of the surface from a base plane.
I’ve only been working with grasshopper for a week or so and have a limited knowledge of all the available functions. Hoping someone might be able to suggest a strategy that might get the result I need.
Thank you.
