hello guys, sorry this might be a very simple question but still learning the basics for GH and having some dumb issues.
So I used a lunchbox plugin to grate a triangular grid… I wanted to get the diagonals and select one of them. As far as I was able to accomplish i could get all the diagonals of the grid with the mesh edges component (also from lunchbox). but when I try to select one of the diagonals with the list item I get only a piece of the diagonal. Tried to join the curves but still get only a part of the diagonal. I want to select the entire line of only one diagonal… is that possible?
hi Baris, thank you for your answer. I tried to apply to a more complex surface and it worked well. Even though I was wondering if I could get a pattern like the lunchbox component does ( if you notice, to create the triangles we need all lines: both diagonal and both orthogonal lines - vertical and horizontal). I was trying to get the triangles without the vertical. However, if i just ignore the vertical lines I get triangles and also diamond shapes (which I don’t want). I tried to find the intersection points between the 2 diagonals but I have no clue how to connect these points in the direction I want to create a grid similar to what the lunchbox component does.
hI HS_kim, thank you for your answer.
this worked well on a plane surface but when I applied to a more complex geometry the code get messed up… I believe because of the vectors get in various directions… do you think your solution could be applied to a more rounded and tri-dimensional shape?
and yes just like this, but I wish I could select one diagonal from the pattern. I am almost there but there is only one problem with the diagonals created… I get this weird discontinuity even my surface being continuous…
I was recently working on a component to do something along these lines…(no pun intended). There are quite a few methods, (as listed in above posts), for getting the desired diagonal lines. I think it becomes an even more interesting challenge when you need to get the surfaces/faces that would follow a a similar form. This takes a stab at getting the surface “strips” that would follow those lines. It’s not ready for release/distribution yet but this is the general idea. Resulting “strips” are all developable, meaning they can be unrolled using a variety of existing plug-ins. (kangaroo’s unroller component). Preview of basic functionality is below.
this is amazing HS_Kim ! It works so well I am still trying to undertand the code deeply but as far as I know this is what I was looking for! Thank you very very much!
By the way, do you think I could generate the triangular surfaces with this? I am trying to create the surfaces with lines or maybe mashing them but still cant seem to figure it out.
