Extrude Mesh Faces In conjunction with a form-finding exercise in Kangaroo, I was searching for a way to render a single, closed mesh as if it were an inflatable form made of individual, stretchy panels – think soccer ball. Since I was already starting with a mesh, I needed something that could extrude and manipulate individual mesh faces normal to the face centroid with a certain degree of flexibility. I couldn’t find much online, so I put together a super basic, simple grasshopper file. Parametric facade apertures on swooping surfaces are out, parametric emoticons are in. bucky was right I’ve used genetic algorithms for form finding with a previous project, and that time I was using a tenuous connection between catia, modeFrontier and Robot. A couple of observations: Galapagos pretty quickly found the overall shape – smaller radii at the extremes and bulging in the middle – the beginning of a sphere. But in general my hypothesis was proven correct. kangaroo tests more » assembly more »

Responsive Skins | An exploration of Paratonic Surfaces in ArchitectureResponsive Honeycomb Morphologies [Gh3D]Continuing with the experimentation and research of honeycomb morphologies and a as example for a Workshop I gave recently I developed a Grasshopper tool for creating a responsive skin system ,using my previous VB script component for creating honeycomb patterns. For more information and definition downlad click HEREFebruary 2012 | ProtoRaptorA Selection of Tessellations_ Upon realisation that a tessellated system would lend itself more readily to self organising structures I began to investigate a series of tessellated geometries generated through the geometry gym plug-in for grasshopper. Here we could begin to visualise the performative qualities of each system of cells in generating a minimal surface in order to reduce material use & increase efficiency of the final form.

Generative Flow | Architecture is changingTutorial 8 - Random Points On SurfaceIntroduction The Result of this tutorial A nice possible option in Grasshopper is to use a random generator to add randomness to your design. The Design The Rhino surface Before we start building the grasshopper model we need to create our Rhino Surface. Step 1 - Creating the basic grid Create the basic grid The first step is to link the Rhino surface within our Grasshopper model. We need to set the surface. RMB on the surface » select “Set one Surface” and click on the Rhino surface To create the grid on the surface we will divide the surface. We want to be able to change the number of divisions in order to change the number of grid points on the surface. Our grasshopper model should now look something like the image on the right. Step 2 - Cleaning up the list of points Looking at the list values When we create a panel and connect the output of our Divide Surface to it, we can see the values within the list of grid points. What we notice immediately, are the list items with the value "NULL".
Reverting values of image samplerHello there, I am making a perforate window mesh with the help of Image sampler. The image is output from Ecotect analysis, in which the daylight factor range from blue(dark) to yellow(light) suggests shaded region(minimum light gain) to exposed region (max light gain) respectively. But as image sampler works, as far i know is by assigning larger values for light colour and lesser for dark colours. Please help me out to invert these values with respect to colour spectrum. Attached are GH file and image used. Thanks in advance. Tags: image, invert, pattern, sampler Attachments: ▶ Reply to This
Lattice LabLATTICE LAB was a two-day workshop on the topic of Subdivision Modeling for fabrication with 3D printing. Workshop Journal Lab participants learned how to create, distribute, and smooth mesh elements through the Plug-Ins Paneling Tools and Weaverbird for Rhinoceros. The Lab curriculum included a series of instructional lectures, lab exercises, and open work sessions. Instructional lectures served to both introduce key concepts and spark discussion amongst the group. Drawing inspiration from the patterns found in 3-Dimensional Lattice Structures, Lattice Lab participants created vast arrays of geometrical units capable of responding to a range of dynamic contexts. Open work sessions offered participants time to develop individual design studies with one-on-one assistance by the Lab instructors.

Primary facade composition: windows and light boxes Secondary facade composition: zinc panels between the primary composition (it might influence the primary composition, because of its size constraints… ) The whole facade could be set out of some modules.

Isovist – grasshopper 3d and syntax (WIP) | spatial[dynamics]I’ve got several ideas/projects in ‘work in progress’ state at the moment related to Grasshopper and Rhino3D… more updates will follow. From: Benedikt M L, 1979, “To take hold of space: isovists and isovist fields” Environment and Planning B 6(1) 47 – 65. “The environment is defined as a collection of visible real surfaces in space. An isovist is the set of all points visible from a given vantage point in space and with respect to an environment.
