Kagome VB.Net | New Grasshopper User Object

KagomeVB Digital [Sub]Stance

Just a follow up to my last week’s post! I implemented the methodology of the Kagome-triaxial  weaving definition into a custom written VB.net component… The parameters remain the same, I believe it is a lot faster than the  definition. The script is written in the newest version of GH to avoid the “old” tags. I also compiled the code into a GH User Object so that it can be easily accessible through the GH GUI. To grab the component go here. It might contain a few bugs as I only gave it a few hours so any attempt to modify it or optimize it is welcome.

Here is a screen shot of the Component live and running.



Kagome Pattern [Triaxial Weaving] Grasshopper Definition

Kagome Weave (triaxial)

The Kagome Pattern is a Japanese Weaving technique used for centuries now, similar or possibly a version of triaxial weaving. The weaving materials are mainly bamboo wood , straws ect. For more on triaxial weaving and the Kagome Patterns jump here. I have composed a grasshopper definition to recreate this weaving technique. It works both on open and closed Nurms surfaces and has a variety of parametrically controlled variables.


This is a quick attempt so it may contain some bugs, any feedback is really valuable. Go to the [Sub]code page to download the definition.



Façade Porosity Adaptive to Sun Path Grasshopper Definition


Creating photo-adaptive facades or building envelopes is a logic and technique I have used several times.  I helped out a friend last week on the same topic, so I thought of  assembling a GH definition to share a similar routine.. In this case a random surface gets tessellated and then perforated accordingly to the reflection sun angle on the surface… Angles closer to zero degrees (vertical to the surface normal) provides as with darker panel. On the other hand greater angles, enable larger solar penetration.


The solar environment is fully parameterized, plus the surface has a variable thickness and panelization. A toggle switch enables the Catmull-Clarck smoothing of the final geometry.
