GH: OBJECT MANIPULATED MESH. This definition shapes meshes with objects 1. Start with some mesh (in this case a box)2. Create objects inside or outside the mesh to manipulate the mesh3. Determine the vertices of the mesh to move via distance to the objects4. Move the vertices toward the manipulation objects5. GH Version Plug-ins Required 1. 2. Tip Try using different meshes to start such as spheres, planes, ect. Octopus. New in v0.3: you can work single-objective problems by imposing diversity as a second objectiveyou can add preference selections that try to get close to the parametrization of that solution, compared to the older preference selection where the respective part of objective space is favouredyou can change the number of objectives during a search3d models of the solutions can be displayed in octpus' objective-space viewportconvergence, genetic distance, and hypervolume graphdifferent mutation operators [HypE, Polynomial, Alternative Polynomial]different reduction operators [Hypervolume Indicator, SPEA2] Octopus introduces multiple fitness values to the optimization.

The best trade-offs between those objectives are searched, producing a set of possible optimum solutions that ideally reach from one extreme trade-off to the other. Results are shown in a 2 to 6-dimensional, solution-viewport that can be navigated like Rhino. Download version 0.3 here: Marching Cubes: Curve Wrapping & More Metaballs. UPDATE: 30-Jan-2014 I have added breps as an input for wrapping geometry (it also can take lines now), as in the above definition. It has been updated for some you can taper a curve at both ends if you choose, you only need to feed one radius, although you can feed as many as you like (it acts like the longest list component). The definition uses kangaroo, weaverbird and nudibranch, although I ahve also included some internalized geometry...but I highly recommend playing with those!

Kangaroo and weaverbird are better-known essentials, but nudibranch is really fantastic too. Enjoy! Some of the work posted lately by Nick Tyrer has gotten me thinking about marching cubes again...I had done some stuff with marching tetrahedra and cubes a ways back, and with some new inspiration (and a little time I could carve out today) I figured I'd take a stab at trying to make it more flexible and robust.

The marching cube stuff is derived from the amazing Paul Bourke's work. Cone.png (1600×993) Marching Cubes: Curve Wrapping & More Metaballs. GH to SVG – your graphics directly from grasshopper. We all know the value of data in computational design field. Many times we need to inform our models with several flux of information and many times we need to show these information using dataviz or infoviz graphics. Co-de-iT decides to maximize the workflow speed in Grasshopper and code some components in order to expor realtime graphics in SVG format readable immediately in your favorite graphics software (Inkscape or Illustrator) or at live, dragging and dropping it in a new Chrome Browser tab.

The components are actually released as grasshopper clusters (they are literally syntax parsers that transform GH data in SVG objects syntax) in order to let anyone to implement the components with other features. The SVG code is really easy to be understand and coded! In the GH definition you will find this clusters: – line SVG – polyline SVG – polygon SVG – circle SVG – curve SVG – text SVG – composer SVG here below another example of SVG dataviz created using the GH to SVG definition.

GrassHopper Scripting 3: Hexagons on a surface. Archsim. Leaf Venation. Hi everyone, I have been trying to replicate an algorithm in 2D, used by nervous system to produce their hyphae lamps (see image below) using grasshopper without any additional scripting. I think this is possible especially with the use of hoopsnake now for performing iterative or recursive functions. My progress so far has got to a point where I can get the vein to grow initially and place some additional nodal points however I am now at a point. It may be possible to continue with the same process however using a parametric script is becoming redundant due to the length and repetitive nature. For a video of the process I am trying to replicate please see this video by nervous system: And check out their blog here: My previous questions and process can be found on a discussion in the kangaroo group: My definition so far is attached to this post.

Regards, Michael. WooJae's Blog. Starling. Starling_0.2 mesh tools. These components enable mesh parametrization, so it behaves like a surface - you can evaluate points at any place etc. In 0.2 release, Starling enabled quasi-polyhedral mesh tools. These new components are organized in a new panel called "Alchemists" : How do they work ? You create polyline and each component converts it into polygonal mesh.

It allows for very fast linear elastic analysis of frame and shell elements in 3d, 2d plate elements for in plane forces, and 3d volumetric elements. All systems can be optimized using built in topology optimization methods and have their results extracted and visualized in a variety of ways. In addition millipede implements a few basic geometric features [extraction of iso surface meshes from volumetric scalar fields or and extraction of curved contours over any mesh] and a few numerical analysis tools [Fast fourier transforms in 1 and 2 dimensions, sparse linear system solver and eigenvalue calculation for large matrices using functionality from the intel math kernel library] The new version of millipede includes the surface reparameterization module that enables the generation of vector field aligned patterns over any mesh.

Rechenraum - Overview. Path Mapper Help. As a result of a request please find a series of examples for using the Path Mapper component. The First installment of this is showing the Path Mapper imitating some already existing components. Flatten, Graft, Simplify and Flip Matrix. There is also an additional example showing Integer Divide to which there is no existing component. For those uninitiated in the dark arts of pathmapper the component can be found on the Sets Tab> Tree Section with the icon of a red cube. Section 8: The Garden of the Forking Path of the Grasshopper Primer 2nd Edition is dedicated to the Tree Structure implemented in GH v0.6.

There is an extensive Help file accessed from the 'right click' Context Menu. UPDATED to correct an error in the Flip Matrix demonstration path_count should be item_count.

Lars Renklint's Page. Continuing to explore the work of Rinus Roelufs, I had some progress with the selfintersecting Moebius band. The holes that permits the surface to weave into itself are now circular. The definition is not all that parametric yet, meaning you can only change the size of the moebius, the size of the holes and whether the moebius band should be twisted… Continue. SR22. Kangaroo discussions and examples from GH forum. Home about us contact sg2011 cluster: use the force Through Kangaroo, the live physics plug-in, this cluster will explore ways of using the simulated interaction of physical forces and real-time spatial inputs to develop novel form-finding processes. news and updates discussions cluster champions members view all image albums videos events No event created yet. discussion Discussion started by Daniel Piker , on 14 Mar 11:53 AM Over the past few months I've posted fairly regularly on the Grasshopper forum about Kangaroo - responding to various questions, often with example files and expanding on the explanations in the manual.

In the hope that these discussions and examples might be useful to others I've collected some of them here: Measuring/displaying stresses. (and also some more general thoughts about structural optimization) distorting a flat hexagonal grid spring rest lengths shrinkwrapping geometry simple catenary. Example files. Edit 29/04/14 - Here is a new collection of more than 80 example files, organized by category: This zip is the most up to date collection of examples at the moment, and collects together a wide variety of definitions made for various workshops and in response to forum questions. Thanks to all workshop attendees and forum members for your valuable input. It is possible I've missed a few useful ones. If there is something else you'd like to see included please let me know The examples below are mostly older, but I will leave them here for now until I am certain all the same topics are adequately covered in the 'official' collection above.
