can you show how to cull the outer pts with your def?
thanks"

3D Voronoi Subtraction
I have created a 3d voronoi by creating a set of points in Rhino and then using the '3d Voronoi' tool that looks something like below: What I am wanting to do is remove some of the polysurfaces…Continue

Trim 3d l-system tree branches using a surface
17 Replies
I have created a series of 3d l system trees from a grid of points. All of the L system trees are of varying heights which relate to a roof surface. All of the branches intersect the roof surface.…Continue

Cull edge points of a grid of varying dimensions
9 Replies
I have created a grid of points and I would like to cull the edge points of the grid automatically when I increase/decrease the 'x,y' dimensions of the grid. How can I do this? Continue

I have created a grid and from the points I have then generated some 3d L system trees (using rabbit) of varying heights which relate to a roof surface above. For the trees that sit at the edge of…Continue

"Great image and an interesting structure. How did you achieve this 3D voronoi in Grasshopper?"

I have created a 3d voronoi by creating a set of points in Rhino and then using the '3d Voronoi' tool that looks something like below: What I am wanting to do is remove some of the polysurfaces indicated in lime and numbered 1-4 so that I end up with the base to create a structure like this:http://www.grasshopper3d.com/photo/3d-voronoi-sculpture/prev?context=user Any help would be most appreciated.

"I have used the PS Recon tool however, how do you then delete some of the polysurfaces from the bounding box so that you get something like the above."

"This is really good, I am wanting to create a 3d Voronoi structure like this too. How did you do it? Can you share your method?"
Michael Smith replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"Thank You
Michael"
Dedackelzucht replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"ah, yeah
the vector does not make any sens after you want a random arrangement.
I would try to skip it, and see waht is happening. Mh but if the solution will be satisfying? The tree structure will lose its strength, and will…"
Michael Smith replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"I think I may have found the source of the problem. Basically the move component highlighted in red is only taking the value form the vector component highlighted in blue. (This happens when I ungraft the T imput of the move…"
Dedackelzucht replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"mh, should work the same way?
Check the point numbers in the outputs, maybe there is a mistake?"
Michael Smith replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"Hi,
Yeah that's really good however, I was also trying to do the same in the first 'quad move' of points as shown in the image below however when I do, I get all the values happening to all of the points. How can I split the…"
Dedackelzucht replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"haha,
you want it all :-)
How do you like this one"
Michael Smith replied to Michael Smith's discussion Trim 3d l-system tree branches using a surface"Dedackelzucht,
I have been experimenting with this definition a bit more and what I want to do is use the range of random values created from the component highlighted (as shown in the image below) and feed them into the x and y…"

- Hey Michael, the strategy that I use to create this 3d voronoi, I must give the merits to Gabe Smedresman, long time ago he developed VB script to subdivide breps geometries, what I did is that I create random points in order to create a volume that could contain this points, (in this case a box, but the volume could be whatever you want) , then I just introduced the data to the vb script component, resulting voronoi volumes. From this point I only classified the data in order to extract the lines to create the structure. Also from this data I used a random selection to extract the volumes that should be solid. If you want the vb script component I can send it to you.
