ry close to the screen (the model unit equivalent of a pixel deep). I am using the DrawForeground override to generate these objects...everything is fine, except that we'd also really like the users to be able to output high quality images directly from the viewport. Using the ViewPortCapture (either to file or clipboard) with higher scales can create some excellent images...but here's where we run into trouble.
The geometry that is created close to the screen through the Display Conduit tiles along with the resolution in the output image...so even though the rest of the model geometry scales up, the HUD geometry stays the same resolution but gets repeated in a grid (2x2 at 2 scale, 3x3 at 3 scale, etc.). What is interesting is any geometry created in the normal model space (say, a circle at the WorldXY) gets rendered correctly. I have also tried using the CalculateBoundingBox override, using bounding boxes for the objects drawn, but it doesn't seem to help.
I have picked up on a discussion over at the McNeel forums, but haven't gotten any guidance over there, and was curious if anyone here had any pointers.
thanks!…

flat) and then subdivide your surface using the divide domain component and feed that into a surface box. Your base geometry, base geometry bounding box and surface boxes will all drive the box morph.
From the looks of your geometry, it appears that it is designed to nest in a particular way that isn't strictly rectilinear, but is more staggered, so that the top corner of one element fits into the bottom corner of an adjacent element. You can achieve this using the box morph, but you have to get pretty creative with how you subdivide your surface:
I'm attaching a couple of files...first of all is your definition with the changes in it to make the above. But also I used some components that I made recently (will release them in a package with a bunch more hopefully soon) called tree sloth, which helps manage data trees and lists. I used a couple of those components, so I'm also attaching the gha for those. Just copy that file into your components folder (under file-> special folders) and restart rhino/gh. The new components are just layered into different parts of the "Sets" components.
To explain what I did: you basically you want to have adjacent sub-surfaces along your guide surface to overlap at the top and bottom thirds. There are any number of ways to extract these surfaces...I just pulled out strips in each column and culled every fourth element, but shifted by one in alternating columns. So in the first column I take strips 1,2 and 3 and skip 4, take 5, 6 and 7, etc. and in the second column I start at number 3, 4, 5 and skip 6, then take 7, 8, 9, etc. Then I collect each of these batches of three strips and take the bottom left corner and upper right corner UV domains to create the target surfaces for the morph.
Hope this helps you out...…

HiIf you are encountering a problem with rhino 6 versions don't worryFollow these steps.1. Download SYNTACTIC from https://sites.google.com/site/pirouznourian/syntactic-design2. Install it and go to the installation folder, Drag & drop SYNTACTIC(green one) over your grasshopper canvas.3. Close your rhino and reopen it. 4. Type GrasshopperDeveloperSettings5. Tick the Memory load *.GHA assemblies using COFF byte arrays option6. Run grasshopper and enjoy plugin

tly light vehicles such as bicycles and variations thereof. Although frame design is mostly of a structural nature, there are a number of elements that interact mechanically. Also, as you may be aware, bicycle and high grade tubing is not of constant section so shelling method in FEA is out of the question, but even so, because the joint needs to be modeled very accurately, that means different geometry and properties for welded area, heat affected area and base material; like so a simpler FEA package may not suffice.
I don't know karamba extensively, rather superficially, actually, but I'm under the impression it mostly deals with beam analysis. Pls correct me if I am under the wrong impression. I must say it would be very nice to have a complete FEA package inside GH really!!
Typical workflow for me would be to model everything in Solidworks, and then export to Ansys Mechanical. Although Ansys needs to read every input and naturally remesh back again, integration within Solidworks, Catia, Inventor, Creo, Solidthinking... and the sort, works reasonably well.
Now, I don't remember Ansys having a Rhinoceros plugin so that you could bridge the 2 together, but maybe I should go check again.
3) Great work with that fractal tree. It's nice to know it is a possibility at least. I have tried Apophysis and others, but to my knowledge there's not an application that could deliver 3D fractal designs in a way that you could further manipulate with conventional modelling techniques, maybe apply textures and render, or export to CAM, 3D printing... etc.
P.S.: I have tried all the apps mentioned above and then some more. All of them have serious limitations when it comes to parametric design. For complex models they crash plenty upon rebuilding... a number of time consuming errors appear, and general work flow isn't very efficient for purely parametric work. Speaking for myself, I'd rather spend the time on a definition that enables me to have full control and then generate a new result within seconds, than model everything very quickly and then taking a long time with each new result.

le] demo):
1. A transformation Matrix is a 4*4 collection of 16 values that "deform" 3d things according the values in the cells. The orthodox way is to deploy "cells" left to right and top to bottom. Rhino does the opposite (why?) hence we need the transpose method.
2. Since "translate" and "perspective" are "symmetrical" the transpose boolean toggle (within the C#) "flips" rows with columns ... so we get perspective or move.
3. When in perspective "mode" the vanishing points are computed internally within a min/max limit (per X/Y/Z axis) thus avoiding the usual havoc with "extreme" perspective angles (very common "glitz" in pretty much every CAD app - CATIA excluded). Vanishing points (and limits) are oriented with respect the pos/neg value of a given control slider.
Note: slider values are percentages between min/max (mode: perspective) and/or actual values*100 (mode: move).
4.In order to start mastering the whole thing: don't change anything: just play with these 4 sliders selected:
5. The 123 sardine cans challenge: even with DeusExMachine = true (see inside C#: that one redirects the transformation per BrepFace and then joins the breps instead of applying it on a brep basis)... odd things (and/or invalid breps) occur ... thus what is required in order to make things working 100% ??.

How I want to communicate this: The depth of transparent cubes is relative to the brightness of a picture (low depth = bright, high depth = dark). Then I assign each cube as red or blue depending on the RGB values of the cube column's corresponding pixel - this is where I'm stuck.
What I've done: I have one image sampler containing a greyscale version of my image which is outputting the brightness measurements. This made into lines, which are divided to create the points from which the cubes are created. (I have had to invert the image in photoshop as brightness gives black a low value when I need a high one, and vice versa)
What I want to do next: In the second image sampler I have an image which has a Red to Blue gradient applied to it. I want to group my cubes into reds and blues depending on the colour values in this image (so they could eventually be saved as a "blue" and "red" stl to be 3D printed).
So columns that correspond to a blue part of the image will contain a completely blue stack of cubes, and the same with red. But where there's a combination of blue and red values I need a combination of blue and red cubes mixed together. I was hoping to do this by turning the RGB values into some kind of ratio that will help assign each cube a group but I'm struggling.
Would love any thoughts on resolving my problem, even if it's only for part of it! This was quite hard to explain so let me know if there's anything that needs clarifying.
Thanks…

[.] Descrizione:
Modulo 1 Il workshop è finalizzato a fornire ai partecipanti i fondamenti della modellazione parametrica e generativa attraverso Grasshopper, plug-in di programmazione visuale per Rhinoceros 3D (uno dei più diffusi modellatori NURBS per l‘architettura e il design). Il workshop mira a gestire e sviluppare il rapporto tra informazione e geometria lavorando sui sistemi di involucro in condizioni specifiche. La discretizzazione di superfici (pannellizazione sia Nurbs che Mesh), la modellazione delle geometrie attraverso informazioni (siano esse provenienti da dati di analisi ambientali, da mappe di colore o da database), l’estrazione e la gestione di informazioni richiedono la comprensione delle strutture dei dati al fine di definire un processo che va dalla progettazione alla costruzione. I partecipanti impareranno come costruire e sviluppare strutture di dati parametrici per informare geometrie ‘data-driven’ e come estrarre le informazioni rilevanti da tali modelli per il processo di costruzione.
Modulo 2 Il workshop, volto a promuovere le nuove tecnologie digitali di supporto alla progettazione e alla fabbricazione, fornirà ai partecipanti, utilizzando Grasshopper, gli strumenti per la preparazione dei modelli 3D di elementi modulari decorativi "bricks & tiles" in argilla la cui successiva prototipazione avverrà tramite fresatura dello stampo con pantografo CNC a 3 assi. Il workshop darà quindi ai partecipanti i fondamenti per l’utilizzo di tale strumento di fabbricazione digitale e si concluderà con la fabbricazione di un proprio modello realizzato durante il corso.
