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.

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. You should have this handy for reference. 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 Line Topology

Oasys GSA GSA will analyse exactly what you tell it to, nothing more, nothing less. So if you input working loads (or SLS) then that is what will be processed. Assuming that you ran a linear analysis, you can then use the Combinations section to multiple the analysis results by the appropriate factor and add them to other analysis results. If your analyses are non-linear then you must not do this and you should instead include the multiplications and combinations within the analysis itself. The bridge load optimization analysis is slightly different in that it will work out the appropriate factors to apply at any location, and give you the characteristic, combination and frequent load values in accordance with EC1. For more information see the help file (Program data > Cases and Tasks > Bridge Loading > Standard bridge Loading > Eurocode loading) and the Eurocode itself.

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! Fast 3d slicer Ive worked all the day in this definition and I hope you like it. With this you can: -make ribs with notches -use the sliders to specify the x and y spacing of a rectangular grid or -use a custom grid (for this you just need 2 sets of lines) -specify the thickness of the material -atomatically place and order the ribs with labels for cut -use a 3d guide for construction -Run or stop the definition It has torus example inside with the custom grid option on. For now (and its just today) all the geometry I sliced worked perfectly. Any suggestions will be very welcome!

Geometry Gym SSI - Structural Analysis Data to/from Rhino SSI (Smart Structural Interpreter) is the plug-in I've been developing that allows data to be transferred to and from Rhino from Structural Analysis programs used by Engineers to assess structural performance and strength. This is currently released for Oasys GSA (which is used at our office at Expedition), and early versions are being worked on for other similar programs. A lot of engineering time is spent on updating and altering structural analysis model geometry as projects and designs evolve and change. You can watch this tutorial on this video link, then I'll explain the steps for you to try. Initial GSA model here. Initial Sofistik model here. Initial SpaceGASS model here. You can find the Rhino model with the a surface representing the desired shape here. Download both these files to your computer. Open the Rhino model above, If you haven't already, install ssiGSA and then open the above rhino file.
