Giulio Piacentino. Culling to create regular patterns – Example 1.4 | Generative Landscapes. While most contemporary design expression tends to avoid patterns like the one above, introducing regular rhythms into projects is still important, and can be done very easily using the “Cull” components in grasshopper. The English verb “cull” implies getting rid of things (such as livestock) in a systematic manner. This is exactly what these components do. You give grasshopper a set of items, and then get rid of some of them using components.
There are a couple of these, but the two discussed in this exercise are “Cull Nth” and “Cull Pattern” There are basically two steps to this simple exercise. Step One – Setup a rectangular Grid This is similar to a square grid, but with a couple of more options. Step Two – Do the cull with Cull N For our first Pattern, we are going to be using the “CullN” tool. Why does it do this? Cull N has limited functionality, but can be used for introducing a simple rhythm into a project. Cull Pattern Variations Below are some simple variations with this script.

Working with Mesh Geometry | The Grasshopper Primer (EN) 1.6.6 Working with Mesh Geometry In this section, we will work through an exercise file for producing a complete mesh solid.
By the end of this exercise, we will have a dynamic definition to produce custom vases that can be 3D printed. Example files that accompany this section: Download Since this definition is somewhat longer than previous examples in this primer, we will first walk through the basic steps we will take: Create a series of circles as a base cylinderUse a Graph Mapper component to define the profile of our vaseConstruct the topology of the mesh faces to produce a single mesh surfaceCap the bottom of the meshIntroduce a twist to the vertical orientation for a more dynamic formAdd corrugated ridges for a textured vaseOffset the mesh surface to give the vase thicknessCap the top gap between the two surfaces to produce a closed solid We have a series of circles stacked vertically.
Next, we will use a Graph Mapper to control the radii of the circles. Learn parametric design, architectural design. Rhino grasshoper.
