The project was developed though both 2D and 3D voronoi cellular structures. This technique was developed in collaboration with Jelle Feringa of EZCT Architecture and Design Research in Paris. For more information about computing convex hulls, voronoi diagrams, and other triangulations, check out the qhull website.

Geometry, Surfaces, Curves, Polyhedra The following is a random collection of various topics in geometry the author has explored or simply documented over the years. Many of the topics include source code illustrating how to solve various geometric problems, or to assist others recreating the geometric forms presented. Notes on polygons and meshes Includes Surface (polygon) simplification, Clipping a polygonal facet with an arbitrary plane, Surface Relaxation and Smoothing of polygonal data, Mesh crumpling, splitting polygons, two sided facets, polygon types, tests for clockwise and concavity, clipping line to polygons, area of a 3D polygon, area of general polygons, determining inside/outside test, intersection of a line and a facet, Eulers numbers. Notes on points, lines and planes Includes calculations for the distance between points, lines and planes. The intersection between 2 lines in 2D and 3D, the intersection of a line with a plane. The intersection of two and three planes. Texture library There are holes in the sky.

alexhogrefe.com/rhinogh This definition was developed for my final thesis project to generate a louver system based on functional requirements within the building. The performance was then tested in Ecotect. A large part of my thesis design involved invertible arena seating with many moving parts. This definition looks at taking any curved surface, and generating weaving geometry across it. The parametric skyscraper uses Grasshopper to generate the entire structure. My favorite definition to date, this definition generates box designs based on real boxes I crafted in the wood shop while in Grad school This definition extrudes geometry based on their proximity to a polyline attractor. Using a definition created by paramod, I wanted to see if I could edit the definition so that different panels could be combined to create a seamless surface This definition takes a cylinder and transforms it based on the location of objects moving around it. Louvers orient themselves towards multiple objects based on proximity.

2011-06-26 We looked at the paper entitled 'Linking Hanging Chain Models to Fabrication' by Axel Kilian as a source of information and inspiration to carry out our next experiment. The next experiment mainly had to focus on utilizing digital form finding methods to add to our methods for producing the next prototype. Axel Kilian, Ph.D. Candidate in Computation, Department of Architecture, School of Architecture and Planning, Massachusetts Institute of Technology, Cambridge, MA. Fabrication output is an integral part of the iterative process and not a post design process. The relationship between form finding model and the translation into volumetric form was explored in a series of small models. His Motivation : Equilibrium solutions can be scaled if the proportional distribution of mass is kept and the geometry of the lines of forces is scaled proportionally. A major disadvantage is that a physical model is hard to measure accurately and disturb the model. model in one given state geometry.

Grasshopper::Lists, Paths, and Trees G03 Due: April 24 at the start of class Spider-webs and Doilies Manipulating Grasshopper data-trees is hard, even when you understand the concept. There is no starting-point file for this -- just open a blank Rhino and Grasshoper file and start in! Mosquito | Studio Nu | SOCIAL MEDIA FaceBook plugin Working again!: The plugins have been reprogrammed so to work with the new Facebook OAuth API. NEW Record Media plugin: Allows you to record social media information from the media components over time without duplicates. Might be complex for some to use at first. Twitter Working again! Ducplicates: The duplicate component has been updated so to make things easier when recordeding tweets and deleting duplicates. Flickr: Search twitter database for photos based on location and tag/title. ImageDownload: Download images from Flickr or Twitter plugins. Bug Fixes: Fixed bugs with Twitter API access and new functions in String Duplicate component. GoogleMaps : Now works for all users, if it was crashing Rhino before , this should fix it. GoogleDirection : get a route and the directions from one location to another, with distance, time, and steps. Location : Get the address of a given name of place or use a GPS point….reverse GeoCode. Flickr EndDate: The date you want to search up to.

reformelb: tower morphology applied to avoid the problems associated with highly internalised buildings, a grasshopper algorithm has been developed to define a series of variables that as a combined system determine the permeability and porosity of each building. the levels of permeability can then be balanced with required lettable floor areas to determine ratios between private, semi private and public space. altering these ratios then thus not only affect the phenomenological aspects of each space (eg. emotive affections based on lux levels or optimal ventilation) but also the economics of each building. site plan with rentable vs public spatial ratios type1 grasshopper algorithm onto tower building inner circulation and curved slabs applied tower morphology diagrams podium grain size iterations
