and you'll probably fall in love. Mesh morphing, remeshing, smooth curves evaluation (see group image), 3d convex hull and last but not least - slFastMesh - which will enable you to stop thinking about meshing parameters and start playing.
What's that all about ? Mesh is embedded to planar form (or spherical), with respect to topology. You draw point on this planar (or spherical) mesh representation and it automatically finds it's place on original mesh.
So lets introduce some "new" words : Mesh-map. Components that create a mesh-map (planar or spherical mesh embedding) are located in the "Cartographers" category.
This is the first step in mesh parameterization. Then you can use slGuide2D (Guides category) to draw some points on the map - guide will lead them to the original mesh at proper position.
The remaining components can be considered as utilities. For me the two most helpful are :
slFastMesh is a really simple, tiny component. It will take any genus 0 intersecting BReps, union and mesh them - so you dont have to choose all the parameters manually. What is so special about it ? Just reference some BReps from Rhino and give it a try. Basic idea for this component comes from Michael Pryor.
slHull3D is incremental 3d hull implementation which I made some time ago and published as vb script component. It takes a bunch of points and creates a mesh hull, which will match perfectly to slSphere embedding.
Special thanks to : Michael Pryor for constant help&support and David Rutten for great advices.

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.

p; 3D Urban ModelingOn the topography subject I get the next message: "One or more boundaries may be outside the bounds of the topo dataset" I'm not sure if it's the .IMG file I'm loading since I found so many IMG files nearing my polyline area (Miami Lat:26 Lon:-81 aprox.) or maybe my polygon doesn't match the topo area? I have no idea why it isn't working :(On the Shapefile subject, haven't been able to find a Building Height SHP File, so far have downloaded around 8 SHP files which only contain Polylines, my solution is to meanwhile randomize Z heights, but of course this data is not "technically" correct.P.S.: I've already tried all example links and also the ones posted by you and Benjamin in this video.Been strugling last few days, hope you can help me, thanks in advance!!…
raphics card (NVIDIA Quatro K4000) that Freeform recommended but that didn't seem to help as much as the memory, especially since it's much cheaper now than ever before so I got the fastest memory I could find too, with heat sinks on it. I only have four cores (i7 @ 2.66GHz not overclocked) but software usually can't use them all anyway except in rendering. I don't even have SSD disks yet, since Windows 7 is so stable I haven't had to reinstall Windows for years which is what it would take to make me go through upgrading my disks. My single monitor is large but not high definition (La Cie 324i at 1920x1200). I have also tweaked Windows 7 to rid it of any fancy interface features, so my system looks rather old school.
Also, I'm an organic synthetic chemist by training, so my patience level is very high with continuous parameter tweaking in Grasshopper and constantly force quitting Rhino by right clicking it in the Taskbar to use "Close window" instead of the inconvenient Task Manager. I rely on the Grasshopper preference settings that turns on recovery file creation, and that system works nearly always, letting you re-open unsaved work with the Solver deactivated as an option so you can change the parameters back to mellow. So when I make things look easy, that's because compared to chemistry, merely quitting a program all day in order to change a parameter in Grasshopper, is something I hardly even notice having to do so often. It certainly bothered me early on, a lot, before I understood that Grasshopper 2 was coming one day, and that the existing program just wasn't designed to handle what it's being now taxed with.…

) 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!

brep.
I am obviusly doing this in grasshopper (using a image to map the lines with the imagesampler) but this question goes beyond the software. it is more about geometry, I guess.
it involves to unwrape a geometry, but having always continuity from one to an other.
here a image of the concept
You have to keep in mind that the brep (in this case a circular shape) its longer than the shape of the plane. so it is difficult to place them flat in photoshop to paint and create the continuity.
here the images that I am using to map the lines on the geometries. I am using a definition that creates lines from a image black&white like this one
but in order to achive the continuity from the ground to the facade of the building I am thinking that the only posibility would be to use a software where I can paint a gemetry in 3D. LIKE ZBRUSH
but how do I get the map back out and flat to use is correctly in grasshopper?
anyone as any ideas?
Please!!!
THANKS!
HAVE A GREAT DAY!
…
3d voronoi from which i extract a cell for each point. After this i need to compute the intersection between each cell and the surface.
I tried two approaches: one with "Brep|Brep intersection" and then "Curve splitting", and another with "Split Brep".
The first solution works (below) perfectly but the "Curve splitting" phase can be bloody slow! Sometimes it requires more than 1.5 minutes
The "Split Brep" solution (below) is much faster, but for each cell it returns me TWO surface: the one inside the Voronoi cell and the one outside. These are inside a three with a branch for each curring surface. The problem is than inside the branches, sometimes the first element is the inner surface, sometimes it's the outer.
Is there a way to use "Split Brep" and throw away the outer surfaces?
Do you suggest any other method?
Thank you very much, and sorry for my terminology: i've been using GH for 2 days :/…
o express my gratitude. I've been experimenting with your definitions (and still am), but let me extend my question.
Actually what I'm trying to achieve, is to recreate another project by Andrew Kudless, the spore lamp (I mentioned the Chrysalis at the beginning just because of the animation, which wasn't included in the Spore Lamp presentation).
Basically the spore lamp seems to me to be something like a preliminary study to the Chrysalis III project (I think it's a similar approach).
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 which then has been planarized, 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)
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 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-released?g...
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: Keep the cells planar in order to be able to loft them later and obtain those pyramidal forms, and assemble easily
Any ideas? Or maybe there's a completely different approach to that?…
