Turn multiple points on a gyroid surface into a graded density volume

[LamboGrasshopper (Stage Dylan Weber)]

Hello,

I was able to plot a bunch of points on the surface of a gyroid. I am using the Dendro plugin to turn these points into a volume. One may ask why I made a gyroid surface, and then turned it into points and then into a volume. The reason is because I want to achieve a graded density over the length of the gyroid. I thought this would be easier using points, instead of a whole surface.

I can’t figure out how to assign different sizes to sections of points (each base cell dimension) in order to create a graded density (gradually increasing thickness) when I convert it into a volume.

Any suggestions would be greatly appreciated, or even a point in the right direction. Below are pictures to visualize what I am talking about, as well as the process in Grasshopper for reference.

Thank you,

Dylan

You can provide a list of Radius in Dendro

So just select radius depending on a position
You can fast populate a mesh using this script, it is not wonderful but it does the job

Cannot figure out any way to thicken and smooth the following mesh

Here a definition that uses my own mesh populate. It is not as beautiful as David Rutten Geometry Populate but it is fast (12 s for 2 million of points). The only trick is to generate enough points on the mesh. You also don’t need to have a fine mesh. There is no smoothing so the result could be better [image] problem mesh thickening 01 LD.gh (40.5 KB)

Why Populate Geometry so slow?

I feel Populate Geometry is too slow comparing to its simple functionality. For example, 50000 points takes 14mins on my machine. Populate 2D was even slower. Why is this? Is it computing Voronoi diagram or something? Is there a way to speed this up?

If the aim is just a variable thickness to the surfce, I think an easier way would be to use the offset and thicken functions in Weaverbird.

For sure it will be better. And also quadremesh of rhino wip could be used to have a nice mesh.

I posted a definition a while back that can assign create variable radii volumes from driver points for Dendro. With a slight modification you can change it to be planar driven as well.
Hope that helps:

Dendro - Dynamically driven variable radius lattice

Had a student reach out to me about this and thought I would share the definition. This is for generating lattice structures with variable radius struts that are driven by multiple input points. This would be useful if you are looking to control the mechanical properties of a lattice by increasing the diameter of the struts in specific areas. ex: If you wanted a 3D printed shoe mid-sole design to be made up of a lattice that had increased compression resistance under the ball of the foot and h…

Thank you Laurent, I will have to try this !

Thank you Charlie, I will have to figure out how to make the planar driven modification. I appreciate the suggestion!

How to achieve this gradient thickness in weave bird, can you share it？
