Modelling pitted surfaces eg Travertine

Hi All

I am looking to create a small mould for precasting with a travetine like surface ie pitting etc. Each mould will be different and there will be most like 10 pieces required. I believe grasshopper would be the best tool...any pointers as to the most efficient/flexible way to do this...and has anyone any examples of something like this as a starting point. 

Please see target surface picture...mostly smooth with pitting details.

    Am I asking something too hard or too easy? Just a starting point...

    Cheers

      Can you be more specific about youre trying to do? do you want to control the details? do they have to be non-uniform like your shown in the image?

      one method could be to use the image (or similar) that you have above, use graph mapper to get the details from the image and use that to build a surface. 

      If you want to have more control (but uniform details) then you could use an attractor to push/pull points - array a series of straight polylines with several divisions, use attractor points to displace points of polylines on z-axis, loft the polylines together. 

      Again, all comes down to the level of detail and control you want. These are pretty simple and quick definitions to build.
