I want the pattern to be mapped like it is in 2d, centric and evenly spread.
The results turn out like in the image and in the GH/3DM-files attached.
I am probably just missing something fairly obvious, like the settings and properties of the surfaces used.
Additionally: is map to surface really the best way to go in Grasshopper.
Squish would do this better …
Edit: rebuilding the surfaces to match each other (e.g. to sweeps) makes it better but the patterns still gets distorted. (see attached GH-file 180907_test2.gh)
A surface-surface mapping that doesn’t distort the circles might be difficult, but I wonder - if what you are actually after is a distribution of not-too-distorted circles on the surface, maybe you can just use the mapping in your test2 file and refit circles to the output
very nice solution! I was about to extract centerpoints but your version is of course cleaner!
Thank you!
But, the question is what I would do if I was given a 3d-model that was designed by someone else, to map onto.
Like e.g. the file attached (iges). 180907_test1.igs (8.5 KB)
Would I have to build a similar refence surface in Grasshopper?
I have tried here, but the pattern maps off-center…
So, when creating a sweep surface by extracting section curves from the imported geometry, then it works. But the imported shape was geometrically regular and symmetrical… Would be a problem again if it was asymmetrical.
I guess one has to find custom solutions?
