Event: Responsive Surfaces Workshop _ LA 2012: faces2012la.eventbrite.com/ The Responsive Surfaces Workshop _ LA 2012 will explore the use of Grasshopper, Firefly and Arduino as creative and technical tools in the design, simulation and prototyping of intelligent building skins. Grasshopper, a free plug-in for McNeel’s Rhino modeler, allows designers to create adjustable parametric forms through graphic icons rather than programming. Firefly is a new set of comprehensive software tools dedicated to bridging the gap between Grasshopper, theArduino micro-controller, the internet and beyond. It allows near real-time data flow between the 3D digital and physical worlds, and will read/write data to/from internet feeds, remote sensors, connect with machine vision protocols, and more. Instructor: Jason Kelly Johnson, Firefly co-developer, Future Cities Lab and the CCA San Francisco Lecturer: Miles Kemp, President of Variate Labs and co-author of “Interactive Architecture” Additional Information: Workshop Location: 8451 Beverly Boulevard, Los Angeles, CA 90048 (GOOGLE MAP) Required Materials: Each participant should bring their own Sparkfun Inventors Kit or equivalent. Software: Please have the following software installed on your personal laptop computer - Rhino (SR9) + the latest versions of Grasshopper, Firefly and Arduino. …; Added by Jason Kelly Johnson at 4:02pm on January 2, 2012

Event: rat[LAB]EDUxMaterialDriven- LONDON 2020:: Parametric Modulations: +Grasshopper3D] www.materialdriven.com/parametricmodulations-ratlab-london www.rat-lab.org/gvslondon2020 // Level Basic & Intermediate (Previous parametric design knowledge not obligatory). // Agenda The workshop aims to provide a detailed insight to ‘parametric design’ and embedded logics behind it through a series of design explorations using Rhinoceros & Grasshopper platforms, along with understanding of data-driven design strategies. An insight to Computational Design and its subsets of Parametric Design, Algorithmic Design, Generative Design and Evolutionary Design will be provided through presentations, technical sessions & studio work. Studio work will be focusing on modulation of geometry and iterative form using Parametric Design methods that will lead to explorations of spatial geometries that can be articulated as architectural constructs or abstract artistic interventions. // Methodology Workshop has been structured to teach participants the use of Grasshopper® (Generative modelling plug-in for Rhinoceros 3D) as a generative tool, and ways to integrate it with architectural design process. There will be a focus on parametric modulation of geometry that can lead to a design process that utilizes data to inform geometry and space through use of Grasshopper3D and its associated plug-ins that would be introduced during the 3-day programme. // Cities & Dates London, UK: 15th, 16th, 17th January 2020 (Wednesday to Friday) Anglo Educational Services (The Montague Room)45 Russell Square, Holborn, London WC1B 4JP, United KingdomGoogle Maps: https://goo.gl/maps/YBeBqv7HCZPqSre46 …; Added by rat[LAB] EDUCATION at 8:26am on November 8, 2019

Topic: Gismo 0.0.3 Release Notes: new component "OSM 3D roof"): 2) Simplified 3D roads can be created by using the network of OSM polylines (through new component "OSM 3D road"): 3) 3D forest.Up until now, Gismo supported generating a single 3d tree whenever such tree was present in openstreetmap.org database. Now it is possible to generate 3d trees in forest areas, by randomly positioning the 3d trees (through new component "OSM 3D forest"): 4) Boolean 3d shapes.Gismo's "OSM 3D" component generates shapes as parts: for example, if a building has irregular shapes across its height, they will all be created individually. Trying to merge them with Grasshopper's "Solid Union" component can sometimes fail.New Gismo "Rhino Boolean Union" components tries to overcome this issue by using a much better Rhino version of this command. 5) Library of common GIS color palettes (gradients).A single component containing 22 of the common color palettes used in GIS applications as ArcGIS and QGIS. For example: elevation, aspect, precipitation... 6) Url to location.Thanks to idea by Alex Ng, it is possible to extract location from a link of the following map websites: Openstreetmap, google maps, bing maps, wego.here, waze: Version 0.0.3 can be downloaded from here: https://github.com/stgeorges/gismo/zipball/master Example files from here: https://github.com/stgeorges/gismo/tree/master/examples New suggestions, testing and bug reports are welcome!!…; Added by djordje to Gismo at 1:39am on January 29, 2019

Comment on: Topic 'Need Help!!!!!!!!!! how to do this?????': ably after some sort of rough cutting you can no longer see. But it's not standard CAM ("computer aided manufacturing") software toolpaths, since they are not parallel to each other, the fine little ribs that is, but sort of web between the bulk fabric like macrostructure. Nor are they of fixed width, but often quite wide, often tapered even from fat to skinny. It's always possible that the entire big/small structure was fully 3D modeled then CNC cut very finely, so we are not really looking at efficient toolpaths at all in the fine structure, but actually CAD modeling, as if the whole thing was 3D printed. 3D printing would of course add its own layer-by-layer artifacts. Here is the original artist's web site, based on a reverse Google image search: http://www.danielwidrig.com/index.php?page=Work&id=CREAM Ah, the artifacts (thick vs. thin tiny ridges) are likely explained by use of a spiral toolpath, which is fast and efficient, or either a circular toolpath, which would add artifacts between concentric circles, but you can see how a ball mill is making a micro-pattern here, over the CAD model of folded fabric, where I added red lines: To achieve this as a 3D model, you would overlay by addition an undulated spiral of ridges on top of a folded fabric model, so just ignore the little ridges and worry about how to undulate a fabric like this, since the micro ridges are just decorative embellishment of the bulk structure. One way, since I don't see any undercuts is to think in grayscale, in order to create a height map. Swirly stuff in Illustrator or Photoshop, or just 2D curves that then become filled in as stripes then blurred like crazy to make gradient transitions, then converted to a plaque to give it height field 3D structure. The artist's Flickr has more detail that makes the little ridges look less regular, and more like webbing that conforms to the bulk structure: https://www.flickr.com/photos/danielwidrig/ Again, so what? Getting the bulk structure is what matters. I don't have an answer yet, but that's some initial impressions. Kangaroo (physics engine) can create fabric and let it fold about but I still think a 2D image strategy may work easier than trying to do physics (!). There are Photoshop plugins that do chaotic swirling patterns, for instance, and I assume you know what a heightfield is, or can look it up. It's just the more white the higher you make it in Grasshopper, via some component. Native Rhino has that too. Native Rhino also had the Drape command, in which you could merely create some 2D construction plane lines and raise them above a surface plane and 3D point edit them a bit to make the middle higher and the ends go down a bit, then drape a plane onto the combination and that would likely give some nice 3D "fabric" structure with the same sharp mountain peaks and smooth hills between them. …; Added by Nik Willmore at 5:33am on October 19, 2015

Comment on: Topic 'Best Uniform Remesher For Patterning Organic Suraces': variable. It's a short enough script for normal users, along with Stackoverflow and Google English language searches to debug in the future. Just try isolating the problem in a copy of the script, paring it down to a few lines that still fail the same way, then ask around, since then you'll likely only have a basic Python issue to figure out. import Rhinoimport subprocess# TO MAKE THIS WORK, RIGHT CLICK RHINO.EXE AND OPENFLIPPER.EXE TO ACCESS THE PROPERTIES>COMPATIBILITY TAB AND CHECK "RUN THIS PROGRAM AS ADMINISTRATOR."# ALSO MAKE SURE TO EDIT THE OPENFLIPPER CORRECT VERSION NUMBER AND INSTALLATION PATH THAT I HAVE HARD-WIRED TO VERSION 3.1, BELOW.# Write an ASCII format STL file for the input mesh, for OpenFlipper to operate on:stl_file = open("C:/NIKS_OPENFLIPPER_PARSER_TEMP.stl","w")stl_file.write("solid OBJECT\n")Input_Mesh = Mesh # Let's not use the Rhino term Mesh in the script itself.Input_Mesh.Normals.ComputeNormals() # NITM ("Not In The Manual") but this is needed first.verts = Input_Mesh.Vertices # Get all vertices of the mesh from Rhino.for i,face in enumerate (Input_Mesh.Faces): # Rhino gives faces by vertex index number.stl_file.write(" facet normal %s\n" % str(Input_Mesh.FaceNormals[i]).replace(",", " ")) # Rhino gives normals!stl_file.write(" outer loop\n")stl_file.write(" vertex %s\n" % str(verts[face.A]).replace(",", " ")) # Rhino has ABCD properties for face vertex index numbers.stl_file.write(" vertex %s\n" % str(verts[face.B]).replace(",", " "))stl_file.write(" vertex %s\n" % str(verts[face.C]).replace(",", " "))stl_file.write(" endloop\n")stl_file.write(" endfacet\n")stl_file.write("endsolid OBJECT\n")stl_file.close()# Generate an OpenFlipper script on the fly in order to alter settings not accepted on its command line:openflipper_script = open("C:/NIKS_OPENFLIPPER_PARSER_TEMP.ofs", "w")openflipper_script.write("core.loadObject(\"C:\\\\NIKS_OPENFLIPPER_PARSER_TEMP.stl\")\n")openflipper_script.write("id = core.getObjectId(\"NIKS_OPENFLIPPER_PARSER_TEMP.stl\")\n")openflipper_script.write("remesher.uniformRemeshing(id,%s,%s,%s,true)\n" % (TargetEdgeLength, Iterations, AreaInterations))openflipper_script.write("core.saveObject(core.getObjectId(\"NIKS_OPENFLIPPER_PARSER_TEMP.stl\"),\"C:\\\\Out.stl\")\n")openflipper_script.write("core.exitApplication()\n")openflipper_script.close()# Windows command line execution of OpenFlipper with argument to run our script:OFS = "C:/NIKS_OPENFLIPPER_PARSER_TEMP.ofs"subprocess.call(['C:\Program Files\OpenFlipper 3.1\OpenFlipper.exe',OFS]);# Read in the OpenFlipper output STL file back into Grasshopper:mesh = Rhino.Geometry.Mesh() # Initialize "mesh" variable as a blank mesh object to hold each face.MESH = Rhino.Geometry.Mesh() # Initialize "MESH" variable as a blank mesh object to accumulate faces.with open("C:/Out.stl") as f: for line in f: if "vertex" in line: q = line.replace("vertex ", "") q = q.replace("\n", "") q = [float(x) for x in q.split()] mesh.Vertices.Add(q[0],q[1],q[2]) # Fill mesh with three vertex lines in a row. if "endloop" in line: # File itself tells us we are done with three vertices for one face. mesh.Faces.AddFace(0,1,2) # Create a single face mesh.
