Topic: Help ! Metaballs to surface in between network of trees: getting answers for on the web. Our goal is to install a scientific research lab in a forest to study the proliferation of a deadly tree disease so we would like to design a sort of big cocoon that is in part randomly generated and that would wrap around the trees inside it similar to how the disease proliferates through the forest... Unfortunately, we are having a few problems modeling it on grasshopper, here are our questions : First off we have generated a grid on which we have attached vertical lines that represent the trees of the forest we are working on, we have also modeled a grid that is the dual to the first one (links the centers of the cells of the first grid together to form another grid). We have generated points of random z coordinates that follow the x and y coordinates of the second grid, and we have applied metaballs to those random points. 1. We would like to know how to create a surface from the curves generated by the metaballs in my grasshopper file ? 2. We would like to know if it is possible to push the surface away from the lines on the grid, as if there was a magnetic field pushing matter away from them ? we are hoping it would look a bit like this (the black lines being the trees and the big grey volume the surface wrapping around the trees, avoiding them) : If you have any ideas of a better way of representing what we want to model please let me know (or if it isn't well explained please call me out on that). What we like about our grasshopper file for now is that you can kind of change the sizes of the metaballs pretty easily, the fact that they are randomly generated and smoothly blend together, but if you know a better way of achieving a similar result please let us know! A few pics of what it looks like as of now : Here is our grasshopper file attached, to generate the metaballs you just have to make a point in the center of the very first cell of the larger grid, so the corner of the second grid, and link it to the point in the grasshopper file. Thanks, Sarah, Vincent and Nicholas…; Added by Nicholas Sandquist at 8:11am on October 13, 2016

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

Comment on: Topic 'Pain Points in Grasshopper': ou want this to work? Yes, that one is on my own to-do list. I'm going to make it as a hidden lines elevation tool to prepare the geometry for presentation in autocad/illustrator. Return of the Lolcats. All I need to put it back is a giant textfile with one image url per line. We might be able to crowdsource it if you want. I really liked having lolcats available on the canvas, but completely understand the volatility of cat image sources on the web. I could start a thread on the forum to compile URLs for the Image gallery component. Animated wires when data changes and solution recomputes. Like, animate them during solutions.. or? Yes. To visualize where things are happening and what is already solved. Could be useful for showing new users how the definition is solved. Or if there is something constantly updating, without it being obvious in the preview. "Select orphaned components", that just litter the canvas without contributing to the solution. What is the metric for an orphaned component? Pressing (and holding) Ctrl+Shift+A for a while allows you to select all objects connected to the existing selection. Ctrl+Shift+I inverts the selection. Del removes the unconnected components. Oh! Yes, that solves it for me. Treemaps. ? Generation of treemap geometry, based on a datatree structure and its content. http://www.cs.umd.edu/hcil/treemap-history/ All relevant data types and components generalised for n dimensions. ? I'm happy with 4d coordinates, vectors, polytopes, transformations, boolean operations, intersections with 1D-4D objects and projecting down to 3-space. Completely generalising everything might be overkill, I admit. A visual drag-and-drop path mapper. ? To visualise datatrees and allow an interactive re-arrangement of paths and data by dragging and dropping (and cutting, etc). It could help new users understand the datatree concept. And maybe useful in debugging very hairy trees. "Convert curve to wire" for decorative code layouts. ? The effect can be simulated by placing a vector image of the desired wire shape on the canvas, adjust component placement, and turn on hidden wire display. Probably a bad idea. Choice to use any bitmap to represent a cluster on the canvas. You can drag+drop any 24x24 pixel image from Windows Explorer onto any component and override the icon. Is that what you're after? No, I'm thinking more like free-form cluster anarchy for the people. Like early 2000s winamp skinning. But, mentioning winamp skinning, I realise it would cause more harm than do any good. Forget it. …; Added by Ola Jaensson at 3:26am on May 16, 2014

Topic: What is this component and where can I find it?: icking on the Canvas or using the shortcut key F4. Type the name into the box that appears and you will be presented with a list of likely candidates. Once you have found the most likely culprit you can selected it from the list and place it on the Canvas. Both Icon and Text If you have downloaded someone else's definition and are wondering where you can get a component from on the Ribbon then provided you have the GH window wide enough to display all components [EDIT: This is now capable of showing any component in the dropdown menus] then you can hold down Ctrl+Alt and click on the component. A series of arrows should indicate the Tab and the Icon you are looking for. Icon Components If you can see the Icon but don't know the name then things are a little trickier but not all is lost because with a little bit of detective work Help is at hand......literally. On the Help Menu you can choose to export Help... This will create a series of off-line web pages, one of which is a summary page titled "Grasshopper(X.X.XXXX) Help Summary" which will list all of the current components grouped in their Ribbon Tabs. With a bit if guess work you can narrow it down to certain categories like Surface or Curve then simply browse down the list. [EDIT: There is also a VB Script component that David has created to produce an image of all your components] File: http://www.grasshopper3d.com/forum/attachment/download?id=2985220%3AUploadedFile%3A1018081 If all else fails post a screen shot of the component in question in the discussion forum and with in the hour if not minutes you will probably have an answer.…; Added by Danny Boyes at 3:16pm on May 18, 2012

Group: Human UI: It was originally developed at NBBJ by the Design Computation Leadership Team over the course of about 10 months in 2015-2016. Primary development by: Andrew Heumann / andheum / @andrewheumann Lead Developer Marc Syp / marcsyp / @mpsyp Product Manager Nate Holland / nateholland / @_NateHolland Contributing Developer ---- Gone are the days of faking a user interface by laying out sliders and text panels and hiding wires on the Grasshopper canvas. Human UI interfaces are entirely separate from the Grasshopper canvas and leverage the power of Windows Presentation Foundation (WPF), a graphical subsystem for rendering user interfaces in the Windows environment. OLD NEW In other words: Human UI makes your GH definition feel like a Windows app. Create tabbed views, dynamic sliders, pulldown menus, checkboxes, and even 3D viewports and web browsers that look great and make sense to anyone--including designers and clients with no understanding of Grasshopper.
