This is based on my failure of creating an optimum solution to planar polygonal subdivisions. There is a method called Tangent Plane Intersection (TPI), explained briefly here (sometimes similar algorithms are called “planar remeshing” and  “variational shape approximation”) which is effectively used in Trada pavilion (here). I tried to implement a similar method using only native Grasshopper components and no recursion, but it quickly became much more complicated than I thought. It was based on a simple idea that I can obtain the tangent plane of any point on a […]

This was my old plan to work with images in Grasshopper. Certainly that was not the result I expected, but this could be counted as a starting point. After seeing beautiful circle packing compositions here, I decided to program Grasshopper, so that it’ll create a subdivision, based on an image data. This was the initial version, just subdividing a plane with voronoi points and visualizing it according to image’s color values of proper UV coordinates: [GHX: 0.9.0014] There is no interpretation on the points, they are just “random”. (Although I’m looking […]

Today, we’ve discussed ways of subdividing entities to create parametric definitions. Curves can be divided into segments, creating snake-like object definitions. This exercise is important regarding the management of data. Vectors and planes are used as reference entities here. Nowadays, it became clear to me that, reference planes are very important because they both include reference points and related vectors as well. The definition studied in this post includes a curve subdivision and a combination of vector / plane management to create what we’ve deserved for: A Taenia-like freak object.. My […]
