# ParametricModel - a library of parts

designcoding Maybe a huge kitsch for contemporary architecture, I know, but a good example of a fundamental problem of constructing geometric relationships. In ARCH362 today, we’ve examined the geometric modeling process that opens us parametric relationships just by converting it into a diagram of design history. You may follow the construction of such a diagram step by step and see the possible parameters emerged from it. Only rule of this construction is the connection from the left side of the component (node) represents an input to that node, and the connection from the right side of the component represents an output of that node. You can download the definition file here [GHX: 0.8.0066] Please note that in this method, first, a geometric sketch is made in Rhino to create an initial object. Of course, Grasshopper is not limited with this method of diagrammatic deduction.

FreeFormFever Fabricate | Digital Fabrication Conference Grasshopper Modules - Proxy Wiki From Phylogenesis, FOA 2003 The following Grasshopper modules were created in consultation with FOA's Phylogenesis, in particular the taxonomy of forms found at the conclusion of the book. Grasshopper is an exciting and evolving modeling platform - the following examples attempt to develop a range of geometric examples to explore its form-making potentials. Andrew Payne, a GSAPP alum, has created a comprehensive primer on Grasshopper that can be found here. Helpful Modules These modules are provided to supplement Grasshopper with a few simple features. Truss Module Grasshopper 3D Truss This module creates an offset truss from a given surface. Point Topology The simplest form of data to work with, points can be propagated into 3D space and can have geometry mapped to them. A Matrix is a 3-Dimensional point set, interpreted as a field of voxels. Download Rhino File Matrix.3dmDownload Grasshopper definition Example-Matrix.ghx A sparse matrix takes a matrix and set of points as inputs.

Grasshopper Resources Solar Calculation Details Solar Calculation Details General The calculations in the NOAA Sunrise/Sunset and Solar Position Calculators are based on equations from Astronomical Algorithms, by Jean Meeus. The following spreadsheets can be used to calculate solar data for a day or a year at a specified site. Data for Litigation The NOAA Solar Calculator is for research and recreational use only. For further information, please see the U.S. Historical Dates For the purposes of these calculators the current Gregorian calendar is extrapolated backward through time. The year preceding year 1 in the calendar is year zero (0). The approximations used in these programs are very good for years between 1800 and 2100. Atmospheric Refraction Effects For sunrise and sunset calculations, we assume 0.833° of atmospheric refraction. The effects of the atmosphere vary with atmospheric pressure, humidity and other variables.
