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 »
February 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. Cantitruncated Cubic 2 3 polyhedra - truncated cuboctahedra, truncated octahedra, and cubes Second smoothest form when tessellated Second most efficient minimal surface Bisymmetric Hendecahedron 1 polyhedron - hendecahedron Fourth smoothest form when tessellated Fourth most efficient minimal surface Regular Octahedron 1 polyhedron - octahedron Sixth smoothest form when tessellated Sixth most efficient minimal surface Weaire Phelan 2 polyhedra - irregular dodecahedron and tetrakaidecahedron Most smoothest form when tessellated Most efficient minimal surface

Parametrics | Pratt Institute Interior Design 659 class blogReverting 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.
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.
Supra | SupracodexA DLA model, now coded in C++ / Openframeworks. The DLA model is a paradigm model for far-from-equilibrium pattern formation. ‘[P]articles are added, one at a time, to a growing cluster or aggregate of particles via random walk paths starting outside the region occupied by the cluster.’ The Ulam spiral (named after its discoverer, the mathematician Stanislaw Ulam) is a rectangalur grid of numbers spiraling out from the center, in which the prime numbers are highlighted. A visualisation of an attracting set of a quadratic recurrence equation exhibiting a very elegant and intricate structure with fractal properties. A simulation of a reaction-diffusion system. The model is coded in Processing as an agent-based Cellular Automaton model. A classic in mathematical visualization, the Mandelbrot set, coded in C++ / Openframeworks. A classic in chaos mathematics coded and visualized with Processing. An agent-based model of diffusion-limited aggregation.
Highly Original 3D Surface Designs For Innovative InteriorsCheck out these innovative surface designs by Giles Miller Studio, guaranteed to make an impression on anyone thinking of redecorating. By placing various-shaped tiles at different angles on a wall, the resulting effect is original and impressive. As you can see in the photos belows, the patterns come in an array of colors, textures and materials, making them easy to integrate in any modern home. Here is a statement from the producers: “Our surfaces allow bespoke imagery to be developed with our clients, and then to be hand-crafted into the materials that we produce. The resulting surface finishes can show patterns, imagery, text, branding or any other visual content our clients desire with a level of intrigue and subtlety not achievable by using traditional color.
| DesignReformThis is a response to a question on the forum. The question is 1. How does one snap in 3ds Max and 2. how can one move things dimensionally. This 3ds Max video tutorials explains both as... I'm going to start this post by saying this is not something I will do regularly but i was compelled in this case to give it a shot. Delete Mesh provides parametric deletion based on the current sub-object selection level in the stack. So.... This is the third part of a series in which I will try and go through all the operations that can be done at the sub-object level of the various geometry types in 3ds Max.LyrebirdThis is the first release of our plug-in to instantiate Revit families using data from Grasshopper. Lyrebird for Grasshopper will create one component, LBOut for sending information from Grasshopper to Revit. Within Revit, the Lyrebird plugin will create a split button with four commands: a toggle to turn the receiver on/off, a settings dialog, a command to select all elements in a particular set, and a command to strip the Lyrebird data from selected element(s). We have tested this project, but it is the first release and it may still contain bugs. Please use it "as is", it does not come with warranties. I spent a lot of time developing the logic and implementing it, please give credit where credit is due. To install: Download the Lyrebird.msi file from below and run it to install Lyrebird for the local user. In Grasshopper, choose File > Special Folders > Components folder. For Revit, copy the two DLL files and one ADDIN file to %programdata%\Autodesk\Revit\Addins\2014.
