There's nothing wrong with the 3dPDF (but I'll mail to you anyway) > maybe you use some archaic Adobe Reader build? Have you configured the Reader properly? Have you ever attempted to exploit a 3dPDF thingy in the past? 3. Most humorous: you mean in the Monty Python way? (WHAT a bunch of genius was that "group" ...). 4.

Comment on: Topic 'Tensile membrane on struts': he normal vector (per quad/tri set). Random means that the vector length can vary between a desired min/max and sin distortion means ... hmm ... something "equivalent". Clash detection (and topology validation) means that a variety of trigonometry based checks are performed in order to assure that tubes and the other paraphernalia ... stay clear each other AND the drilling axis in the balls are doable. But this is only half the bacon: since roofing material (say VM Zink and the likes) usually imposes several restrictions (for instance: you can't "bend" a VW sheet beyond a given angle etc etc). Then coordinate systems (Planes) are made that are used in classic Plane to Plane transformations: i.e. take an instance definition related with a part of the system (sleeve, cone etc etc) always defined at WorldXY and put it in the desired plane.This has severe limitations in Rhino (actually is undoable and thus I very rarely do this type of work in Rhino/GH). What limitations may you ask? Well ... imagine fully parametric feature driven solids (the nuts and the bits of the system) that MUST comply (NOT yielding some clash, that is) with the whole topology OR they must change OR the topology must change: stuff for CATIA and the likes. Then the structural department evaluates the whole thingy and gives the OK - if not another variant is attempted etc etc. Then connectivity trees are made that relate nodes to edges etc etc ... in order to assemble the thing in real-life. Then it's roof/envelope time ... and that is a pure nightmare. BTW: having some NVidia Kepler K4200 (and up) is a must ... other wise ... well ... dealing with 20++K "objects" is not that trivial. NEVER attempt to do that type of stuff using, say, a laptop and the likes.…; Added by peter fotiadis at 9:07am on December 3, 2015

Comment on: Topic 'Remeshing with a limited set of triangles': triangles. Here's a mesh before this clustering: and after: In general this won't lead to a very smooth mesh, but you can get strict edge lengths. I attached the definition for this below. There is a slider for how strongly vertices try and keep near their original locations - by adjusting this you can vary the priority of exact edge lengths vs closeness to the original shape. This is just a start though - there's lots more work that could be done along this direction. For instance, instead of fixing the target lengths once at the start, the groupings could be adjusted iteratively using something like K-Means clustering. Slightly more involved would be to make a custom goal which adjusts whole triangles instead of edges. It is sometimes helpful to think of triangle shapes as points in a three dimensional space, where the coordinates correspond to edge lengths. However, you need to also account for the fact that a 3,4,5 triangle is the same as a 4,5,3 triangle, and so on. …; Added by Daniel Piker at 10:12am on February 23, 2016

Comment on: Topic 'Please support an effort to start a stack exchange site for computational desig…': am to find the coverage for various public-transport stations and is interested under what conditions that coverage will poorly represent reality, then that would fit perfectly within your proposed forum, but the SO people will close it as off-topic before you can say directed-infrastructure-networks. Or discussing which properties of a transport network would be sufficient to encode into a graph in order to give a model accurate enough for early design iterations. Or discussing the fabrication costs under various manufacturing methods of elements (a, b, c, ...) with amounts (K, L, M, ...). ie. is it cheaper to manufacture façade panels using manual welding if I have 50*a + 50*b + 25*c or would it be cheaper to have 120*a + 3*b + 2*c? Or discussing the visual aspects of various types of geometry. Do Bezier or Akima splines look more natural? What about them makes them look natural/unnatural? Can people tell the difference between a perfect circle and a circularish Nurbs curve with 12 points? Does it matter whether the Nurbs curve is small or big? Next to a perfect circle or not? Horizontal or vertical? What equation would better describe experienced time by humans travelling from A to B rather than measured time? How can I find out under what wind conditions this sharp edge on my building will start whistling? How much might the potentially bad smell of this cheaper material lower the value of my building?…; Added by David Rutten at 2:48am on April 16, 2016

Topic: Biomorpher 0.7: tps://github.com/johnharding/Biomorpher/releases/tag/0.7.0 Change log: Geometry input takes Curve and Surface geometry as well as meshes. Creation of the ‘Biomorpher Solution’ parameter for internalising data. Complete overhaul of the Reader component now using Biomorpher solutions. Lists of performance values can now be used with repeated names automatically indexed. Main component in ‘galapagos pink!’ Incorporated elitism into selection to negate losing ‘best’ designs between generations. Optional elitism mutation. Restart button for a new evolutionary run negating the need to restart Biomorhper. New scatter graph plot for comparing two performance criteria. Performance plot now includes current population data. GUI grey colour to relate to standard Rhino background. Main control area is now on left hand side. K-means display angles are distributed evenly. Fixed min-max bug on performance graph. Minimise and maximise criteria clearly labelled. Performance display above design now based on radius rather than opacity. Evolutionary history justified correctly. Scrollbars now visible on history canvas. Donate button in case you wish to say hello and buy me a coffee :) Thanks and please take care during these times, John.…; Added by John Harding to Biomorpher at 8:26am on July 7, 2020

Album: 17.03: Avalon I y II [2017]: ades del Espacio en 1981). En este, O'Neill propone la colonización del espacio para el siglo XXI mediante el uso de ingeniería espacial construida con materiales de lugares como la Luna o asteroides. Consta de dos grandes cilindros de rotación opuesta, con dimensiones de 3,2 km de radio y 32 km de largo, que están conectados en cada extremo por una varilla a través de un sistema de rodamientos. Rotan a fin de proporcionar gravedad en sus superficies interiores, que estarían acondicionadas como un medio de vegetación natural con árboles, hierba, arroyos y lagos y es el lugar donde se desarrollaría toda actividad. La circunferencia del cilindro se dividiría en seis regiones, tres “valles” habitables alternando con tres hileras de ventanas que permitirían el paso de la luz solar. Además existiría un anillo exterior para la agricultura de quince kilómetros de radio, el cual gira en una velocidad diferente a los cilindros. La zona industrial y la fabricación estaría localizada en eje del cilindro, detrás de la antena parabólica. En esta zona la gravedad es mínima, algo que se tendría en cuenta en algunos procesos de fabricación y otras actividades de la colonia.…; Added by Miguel Guzman at 8:57pm on May 8, 2017
