I’m trying to create a pipe Delaunay structure to 3D print, ideally one in which the higher the gradient the smaller the triangles, to differentiate it from a regular triangle mesh and give it a more structural character. Recently my school changed to rhino 6 and I can’t find a way to translate a 2D Delaunay into a 3D double curvature surface.
In a past discussion forum I found a reference to a plugin called MeshEdit which contains a component called “3D Delaunay”, but it only seems available for Rhino 5
I also downloaded a plugin called SuperDelaunay and worked around one of their tutorial codes but I’ve not been successful in translating a 2D code to 3D
Hi @martinsiegrist, we only have Rhino 6 not Rhino 7 I don’t see TriRemesh in Rhino 6
besides this, I found an old discussion where someone brought up a similar topic and someone suggested “you are after a Del solver that could accept a Surface as “guide” (for instance your tube like facade, the roof etc etc)” However the discussion was never continued. Don’t know if this might be a dead end or not?
It says that the platform is Rhino 5, but it doesn’t mean is only avaliable for Rh5, almost everything that works for Rhino 5 works for Rhino 6 or 7 as well.
It sounds like maybe you are after a mesh on a curved surface rather than a volumetric mesh (instead of triangles covering a surface, a volumetric mesh would be tetrahedra filling a volume).
@DanielPiker Thanks for the reply! is there a way to control the density of the mesh according to the gradient? and/or is there a way to pipe the mesh? I ask because I’m only used to work with curves not meshes
Yes, you can define any gradient you like.
In that example I showed it with the gradient in the Y direction.
To use something different you need to create a value for each point of the input mesh according to its location.
Here’s a file showing examples of sizing by surface u parameter, or by proximity to a point sized_mesh2.gh (233.4 KB)
@martinsiegrist at this point just for curiosity where can I get the WIP version of Trimesh? I found NGON plugin, seems to be very good for what I am trying to do.
@Dani_Abalde you where right it does work in Rhino 6 as well, I guess now I know. on the other hand I am sure that I am doing something wrong, I feel the problem is establishing the surface as the boundary for joining the points, right know the Delaunay is connecting all points together. I know @DanielPiker already solved the issue with another method but I would still want to know if there is a solution with this approach?
Many thanks @DanielPiker! you really solved it in no time!
Not wanting to be someone to abuse here, but since I’m studying architecture I was interested in knowing if there is a way to link the tessellation or triangle division based on the forces, like a type of optimization, considering the form. Is there a plugin or tutorial that could help me with this? if you could point me in the right direction I would appreciate it infinitely!
Thanks @DanielPiker you’ve been so helpful! Great to know that, I will try it later in my personal laptop, don’t think my school will let me install a WIP lol
