erning how to do that on a sphere.
So I know already all the different approches of how to get a relaxed voronoi pattern on a free-form open surface, but still don't know how to obtain the same elegant effect on a sphere (or an ellipsoid closed surface, whatever), or how to relax the facet dome cells.
Andrew stated on his site that he used kangaroo for this project, so the Spore Lamp consists in my opinion either of a relaxed voronoi 3d diagram (b-rep, b-rep intersection) on a sphere the cells of which have been planarized later on, or more likely it is a sort of relaxed facet dome.
The trick is to:
1. obtain a nicely-balanced voronoish diagram (or facet dome cells) on a sphere
2. keep each cell/polyline planar (or force them with kangaroo to be planar) in order to move scale and loft them later on.
Here is what I have by now.(files: matsys spore lamp attempt)
That's the closest appearance that I got so far (simple move scale and loft of facet dome cells with the amount of transformations being proportional to the power of the initial cell area: bigger cell = bigger opening etc.) - with no relaxation of the diagram. But it's obviously not the same thing as the matsys design.
Here are some of my attempts of facet dome relaxation, but well, it's certainly still not the right approach, and most importantly I don't know how to keep or force the cells to be planar after the relaxation.
1. pulling vertices to a sphere - no anchor points. That obviously doesn't make sense at all, but the relaxation without anchor points gives at the beginning a pattern that is closer to what I am looking for. (files: relaxation 01)
2. pulling vertices to a sphere - two faces of the initial facet dome anchored (files: relaxation 02)
3. pulling vertices to the initial geometry (facet dome) no anchor points (files: relaxation 03)
The cell pattern of the lamp kinda looks like this:
You can find it here: http://www.grasshopper3d.com/forum/topics/kangaroo-0-095-releasedgroupUrl=kangaroo&x=1&groupId=2985220%3AGroup%3A120977&id=2985220%3ATopic%3A972434&page=2#comments
Done with Plankton (of course without the "gradient increase" appearance), but in fact not, I took a look at Daniel Parker's Plankton example files, and it's not quite the same thing. Also the cells aren't planar...
The last problem is that during the relaxation attempts that I did, the biggest initial cells became enormous, and it's not like that in the elegant project by Andrew Kudless, that I'd like to achieve.
So to sum up:
Goal no 1: Obtain an elegant voronoi /facet dome cell pattern on a sphere (or an ellipsoid surface, whatever).
Goal no 2: How to keep the cells planar in order to be able to loft them later, obtain those pyramidal forms, and assemble easily
Have you got any ideas? Or maybe there's a completely different approach to that?
Cheers, and thanks in advance…

rent actors to work together in real time on an architectural project.
DixieVR was born from the idea that virtual reality could become a fantastic tool for architecture and architects, not only for virtual tours but for the conception at its very core. Inspired by the efficiency of sandbox games, DixieVR will allow you to build a fully parametric 3D model from scratch in a very intuitive way and to simulate various factors like natural and artificial light, gravity, and more. DixieVR is also multi-user oriented : several people, architects or not, are able to work together in real time on the same 3D model and in the same shared immersive environment !
The project started in the Digital Knowledge department of Paris-Malaquais Architecture School.
The DixieVR Softwares can be found here : dixievr.github.io
// Interoperability
DixieVR deals with .dix files. For more information about this file format, please refer to the Interoperability documentation of DixieVR.
You can use this DixieIO plugin for Grasshopper/Rhinoceros for exchanging data between DixieVR (PC) & DixieViewer (Android).
You can import or export objects at any time inside a DixieVR scene. The Software also come with a library of premade objects that you might find useful. Adding your own premade objects to this library might be a good habit.
If you are hosting a scene, you also have the choice to open a .dix file directly from the main menu, this will load the last scene in which the geometry has been saved.
// Plugin
The DixieVR Plugin can be found in the Extra tab, come with 3 components and a example definition:
Dixie2Gh : Import DixieVR geometry to Grasshopper/Rhinoceros reading a .dix file (up to 1000 beams and/or 750 faces).
G2D_Polylines : Export Grasshopper/Rhinoceros Polylines to DixieVR writing a .dix file (up to 1000 line segments).
G2D_Mesh : Export Grasshopper/Rhinoceros Mesh to DixieVR writing a .dix file (up to 750 triangulated faces).
To install:
In Grasshopper, choose File > Special Folders > Components folder. Place the DixieIO_01.gha file there.
Right-click the file > Properties > make sure there is no "blocked" text.
Restart Rhinoceros or Unload Grasshopper.

...where Vicente Soler suggests a simple method which calls a command from Rhino into GH. I discovered, talking with Vicente that now the language to use is RhinoCommons but I didn't still reached a solution, being a dummie for scripting.
Does anybody can help me with this problem?
Here's the code that I'm trying to implement (it is written in RhinoScript actually):
Private Sub RunScript(ByVal x As Object, ByVal y As Object, ByVal z As Object, ByVal idObject As Object, ByRef A As Object) Dim sIfcType, strObject Dim strIfcColumn, strIfcBeam sIfcType = Rhino.GetUserText(idObject, "TypeObjetIFC") If ((sIfcType = "IfcBeam") Or (sIfcType = "IfcColumn")) Then 'MsgBox "median = " & y & ", min = " & x& ", max =" & z Rhino.SetUserText(idObject, "Longueur", z) Rhino.SetUserText(idObject, "Largeur", x) Rhino.SetUserText(idObject, "Hauteur", y) End If End Sub
I just would like to add extra-information to a selected list of 3D geometries by managing the UserText data.
Thanking you in advance for your attention I'll wait for an your answer about this theme.
Sincerely,
Matteo…

rection: there's no visible demand. Explanation: a lot of AEC oriented people (Smart Geo daydreamers) they think - potentially - about GH but they are rejecting it for more than obvious reasons: our job is 1% about the smart thing and 99% about the structured aspect of the smart (or stupid thing).
Back to that "hangar" : The primary role of this GH definition provided herein (and hopefully some future updates) is NOT to outline some academic solution (via some abstract collection of pipes/lines/points/surfaces) ...but to place in 3d space - properly structured - all the real-life (hmm, he he) bits that can compose the actual project. Of course if the bits could be parametrically driven assemblies ...well...you get the gist of the message.
All in all: I think that Engineers who are GH skeptics could see GH with a totally new perspective if, say, a collection of similar examples/test cases could be available for demo/evaluation/whatever > Ah! at last : this appears to be a real thing > what software did it? > say it again - Grass Components you said? > what sort of name is this? ... etc etc etc.
But since a similar development is quite expensive (and requires a team of several gurus), maybe this is rather a future potential task for the GH/Rhino people if they think that the AEC market segment could be beneficial for their products. Combine a similar capability with tools like yours and/or Evolute (planar quads are "a-la-mode" these days).
PS: forget trivial stuff > what about Stefanie? (plan B : better something than nothing)…
things I need to keep in mind are that, 1) I'm the only tool guy on this project, and 2) I need to generate results in my application domain - and Rhino, Grasshopper and my own code are tools, not results. If I spend all my time developing tools (or learning how to develop tools) then we're never going to get across the finish line. I can perhaps take a longer view on my tool investment once I have the "core" functionality in place. But I'm not there yet.
I've mapped out the various algorithms I would use for each task of the toolset I'm developing. For example merging surfaces was supposed to simply involve intersection/split/cull/join. That intersection operations don't always return complete, accurate and usable results throws my plans into the air. Data flow programming of genetic algorithms fits my background of 30 years programming and 5 years of 3D design. Diving more deeply into the underlying math of B-rep geometry is a rabbit hole I didn't budget falling into.
You bring up other architectures like solid modeling and features. R/GH are just 2 of many, many tools I've looked at to achieve my goals. No single tool or ecosystem looks complete enough to meet all my needs. My prior stop on my quest was OnShape. I found much to appreciate there, but it's still VERY early in their development. (I personally think they are a decade away from having a solution worth investing in.) R/GH seems fairly mature, but I'm already hitting walls like this. There are always struggles and never an ideal solution.
Thanks for your insights,

component in GH for a project im working on. as part of that component I want to dynamic show text the rhino viewport but I don't want to have to return a value that I then plug into the "text tag 3d" component. I want to build a similar method into my custom component.
therein lies my problem. I haven't yet figured out how to get my vb code to produce text.
my latest attempt looks a little something like this.
Dim TestPoint3D As New rhino.Geometry.Point3d(0, 0, 0) Dim TestVect As New rhino.Geometry.Vector3d(0, 0, 1) Dim TestPlane As New plane(TestPoint3D, TestVect) Dim TestText As New display.text3d("bob", TestPlane, 10) ListItem = TestPlane TextItem = TestText
but I get nothing out of it.
latest theory is to try using "Draw3dText Method (Text3d, Color)" but this is where ive hit a wall
if I understand how this works than I would think I would code this
Dim TestText As New Rhino.Display.DisplayPipline.Draw3dText( text here, and color here)
but the hint that im getting after "DisplayPipline" doesnt show a "Draw3dText" method?
so im confused?
again my overall goal is to get text to display in the viewport directly through my component
any thoughts or ideas, or if im even in the ballpark on this one would be helpful.
thanks!…
) In the Rhino view port it is not possible to modify it until is backed (and I don't want!) I need to place several images each one in a different place.
2) Is it possible to use another component THAT DO NOT CONVERT INTO BLACK AND WHITE, the pictures??. I need to set COLOR images in a 3D model, using grasshopper. thanks!
Any comment or suggestion would be welcome!!!
Thanks a lot!
