Flat voronoi cells on surface.

hello,

any idea on how can i get flat voronoi on surface? the idea is to constrain de voronoi vertices to the surface, but get straight edges for the voronoi and not curved ones..

thanks

ps: i am looking for something similar to this:

hello dani,

try the "map to surface" component. You can create your 2d voronoi as you wish (using the voronoi component in hte mesh toolbar) , create/deform your surface as you wish, offset/fillet/chamfer your 2d voronoi cells (curves, after joining them) and then map them to your final surface. if you want your cell to be on the surface - after the last step you can project the resulted "oriented" curves on the desired surface.

Give it a try maybe it s what you were looking after

100% working! if not- rebuild lines of voronoi

take a look at the file. can be a lot smarter, just a small example - just input some points and draw a box which contains them.

thanks!!! it works..

have some problems because the surface i am targeting its toridal, and the voronoi doesnt fit exactly in the "edge", anyway its almost all i want to continue.

Just a reminder that it is not very nice to reference material without including the source...especially when the source is a member of the grasshopper community who regularly contributes to answering questions like this. But just taking images from my website without any link or reference makes me less willing to share my work or thoughts with others.

sorry, it was an image some friend shared with me just as reference of a conversation we had.

awesome works!

hi andrew. Have i understood correctly from your surface voronoi drawings that the curvature analysis creates the points for generating the voronoi structure? could you tell me what are the other ways i can generate these points? im trying something a href="http://www.grasshopper3d.com/forum/topics/guide-a-newbie">http://www.grasshopper3d.com/forum/topics/guide-a-newbie> to generate an organic road/plot network in for a settlement and would appreciate some guidance.

Hi men, I saw you web page and i like your example, ... I am a rookie, I'm starting ... can you do a tutorial ??? please !!! thanks. good day.

hi !!! I saw your example ... and ... I can't to do a voronoi in a surface, I have a "pointcloud:curvature analisys" (step 3 in your example), but I can't go to the four step "Voronoi cells:pointcloud", can you help me please ??? thanks.
