Dimpled Surface Texture


(Peterwells) #1

Hi,

I’m trying to create a surface with a similar texture to the attached image, I guess using grasshopper would be the best way to achieve this, but am new to it so I need some guidance.

I have managed to create the 2D pattern with a voroni, but am not quite sure how to go about creating a consistent 3D curved effect for the resulting surfaces.

I feel there is probably a straightforward way of doing this, but I don’t know what I should be searching for help/tutorials or a solution.

If anyone knows how to do it, what process to use or can think of another way of achieving it, it would be kindly appreciated!

Assuming its a planar surface you can use the following: It employs Patch and only two curves per surface, so if you want something smoother, you’ll need to add more curves.

Just realized this won’t work. Using Patch creates surfaces that cannot be joined using Brep Join afterwards.

This gives a single Brep but because the voronoi cells are angular, the dimples are also edgy.

If you’re not tired of me already, try this:

(why are these images not clickable to see them full size?)

Thank you all so much for the quick replies - i’ll give this a go tomorrow.

They are. At least for me

They are now for me too but weren’t at the time I posted them. Thanks.

Seems to have worked!

Thanks again!
