of the point cloud. It is super quick, compared to what you have seen so far in Rhino, to load and display point clouds, as it works on multiple threads. Amongst others you can section the point cloud for referencing your footbridge, decimate it as needed for creating the enviroment, denoise it, clip and save parts of point clouds etc. You can right click the cloud components, giving you access to dynamic preview of the cloud, so that it does not drag in viewport while panning and zooming and at the same time controlling the "thickness" of the points in viewport, in case your camera gets close to the point cloud. It is a matter of visual preference.
I think that even 200mil points can be loaded with volvox.
Some references
12million points
13million points
13million points (right click dynamic settings low thickness)
13million points (right click dynamic settings high thickness)
15 million points (around 20sec!! to l0ad)
My pc (i7 3820, 32gb ram, gtx670 4gb) felt comfortable working with up to 15 mil point clouds. But that has to do with hardware along with your patience while working.
All clouds have been loaded as .txt files where the mask describing the info was x,y,z,r,g,b,u,v,w. Depends on how your data is in-text formatted.
You can check fly through animations all done with gh and Volvox here

ly 26-27-28-29 (digital fabrication)
The third edition of digitalMed Workshop is structured as a design laboratory. Participants will learn the challenging process of producing ideas, projects and research analysis that are to be developed through specific software and concepts that emerge through the use of mapping, parametric design and digital fabrication.
The workshop will take place in the city of Salerno (Italy) and it will last 11 days structured into 3 intensive weekends: July 13-14-15 (mapping); July 19-20-21-22 (parametric design); July 26-27-28-29 (digital fabrication).
Goals and Objectives:
We aim to make clear the theoretical and technical knowledge in the approach to parametric and generative design and digital fabrication. (From collection and data management, to the manner in which these inform the geometries, to the fabrication of prototypes.)
Participants will also have the opportunity to practice the new knowledge gained in the design laboratory through project work.
Project Theme:
"Urban Field" Identify, study and analyze the system of public spaces in the urban area of the city of Salerno.
Connection, mutation, generation and evolution are the themes to be followed in project work.
Brief Description of Topics:
- Mapping. Our reality, in all its forms, has studied through concepts of the theory of Complex Systems. The techniques that will be used to study events and places of reality, will work for the management, manipulation and visualization of data and information. These will form the basis for project management and driven geometry, conducted during the second phase of the workshop.
- Parametric Design. Introduction to Rhino* and Grasshopper. Specifically, we will explain the concepts with which to work with the software of parametric design and how they function. Through these tools, we will arrive at the definition of systems of mathematical and / or geometrical relationships that are able to generate and govern patterns, shapes and objects that will inform the final design.
- Digital Fabrication. In this phase, participants of the workshop are organized into working groups. Participants have access to materials and conceptual apparatus that will take them directly to the fabrication of the geometries of the project, with the use of software CAD / CAM interface and the use of machines for the digital fabrication.
The DigitalMed workshop is organized by Nomad AREA (Academy of Research & Training in topics of Contemporary Architecture), in collaboration with the City of Salerno, the Order of Architects Province of Salerno and the National Institute of Architecture In / Arch - Campania.

etails elements for more understanding of local problems.
The idea is to get information on the angle for each panel for CNC lasercutting machine.
The main problem, I think is to control the angle to assemble all the elements that will be lasercut. I explored the vectors along the panel but I am lost in finding a way to control this.
I tried also to create finger-joints or jigsaw joints on the edge without success.
The issue would be to able to unroll the surface with the complete control on angles.
If I am just unrolling the surface without knowing how to assemble them it will be random asembling and the tolerance will reck the model. Don't you think ?
I also thought about radial nodes
Does thoses issues are making any sense for anyone here ?
Could you possibly help me find out answers for thoses problems ?
Moreover I have saw this project and they have mastered those problem.
Would you be able to tell me more about it ?
http://www.oliverdavid.de/?page_id=36
I am trying to fully comprehend also the offset properties to create thickness on a mesh in order to turn it into a surface for an eventual "unroll surface command"
It will be ideal if you could answer me with some tips on how to solve those various problems. I am lost and I spent more than 20 hours trying to solve those issues without success.
Thank you for your time.…

the use of digital technologies as architectural design tools. The workshop " Computer Aided Design: parametric design and digital fabrication " aims to do some introductory teaching in the use of some of these tools.
The workshop will focus on the use of computational models of parametric behavior for generating architectural forms. The generative capacity of these models it will be tested in the development of designs defined by repetitive non-standard components, based on the parametric control of its variations and series differentiations. This process will be developed by the use of a three-dimensional modeling software - Rhinoceros, associated with an application for visual programming - Grasshopper.
The last day of the workshop is dedicated to the use of digital manufacturing tools in architecture. Part of the work will take place at the facilities of the Institute of Design of Guimarães (IDEGUI) providing for the use of their laboratories and manufacturing CNC machines (computer numerically controlled).
At the end of the workshop, it is intended the students to understand that the use of digital technologies in architecture can overcome representational functions, and their integration in the design conception, analysis and construction enriches the methodology of project development.
Terms & Participants
The workshop will take place at the School of Architecture of the University of Minho (Campus Azurém, Guimarães) and the Institute of Design of Guimarães (Couros, Guimarães).
The workshop is pointed at students who attend the 3rd year and 4th year from MiArq, EAUM.
The maximum acceptance is 20 students and a minimum of 10 students.
Deadline for entries is April 11 and must be performed by eaum.pac@gmail.com.

ne. Though I suppose providing a help file which lists some useful tricks for some operations would be a good place to start.
It would be possible to add persistent undo to Clusters, and it wouldn't even be that difficult. Adding undo data into the GH file is something I've been meaning to add since the first day of undo/redo, and the plumbing is in fact there, but it was never fully hooked up. I will definitely try this for GH2. And I'll also have a think about how to implement version history for clusters.
Phew, my brain hurts even just to think about this. I suppose step one would be to write a clever merge algorithm for two files that have some things in common and some not. But even that will be tricky as heck.
This is a major problem. First of all, running the solver in a thread and keeping the UI alive will only slow things down even more. On a file which takes 15 minutes to solve that's no big deal, but you certainly don't want to be adding a 20 millisecond delay to a solution which only takes 30 milliseconds.Multi-threading will be something I'm going to try and implement in GH2, but there's only so much I can do. If you run a solid boolean operation on a boatload of shapes, it's a single operation that is performed inside Rhino and there's nothing I can do to make it run on multiple threads. This is in general an issue, sometimes it takes a long time because there are many operations to perform; like offsetting 2500 curves. I can probably multi-thread that provided the Rhino curve offsetter is thread-safe. However stuff may also take a long time because there is a single operation (like the aforementioned huge solid boolean).Lastly, I have no way to predict how long a component is going to take. I can probably work out how far along in steps a component is, but not how far along in time.
What would you do with a solver which runs in the background? How does it differ from only running solutions when you want to? Let's say the solver is threaded and the canvas remains responsive. As soon as you make a change to the GH file, the solver needs to be terminated as it is now computing stale data. Wouldn't it be just as effective to disable the solver, make all the changes you want to make, then press F5?
Just because something runs in a thread doesn't mean you can shoot it in the head any time you want without consequences. Aborting threads typically means setting a boolean somewhere and then letting the thread commit suicide, while performing all the necessary cleanup. If you just destroy a thread there's no saying in what state you leave the memory.
I think a good place to start with these sort of problems is to keep on improving clusters, add more flexible structuring UI such as Layers or Filters or Pages or whatever to the canvas, add ways to share data between remote parts of a file without suffocating the display with wires, and to provide easy ways to temporarily disable parts of a file (think of it as Clipping planes for GH). That way you can make local changes and see local effects before solving the entire file again.
I'm certainly impressed by the sheer extent of the file you people made, it will be a lovely test case for UI improvements.

er" logic but it miss when comes the copy or offset.
Here is my following logic
Take the square of 25 m x 12 m ; make it a surface
I divide it in "blades" of 20 cm
I take the edges of the "blades",
I divide this edges in 40 points (or equivalent) (A)
I identify my curves (curves) which are on the floors, which are curves (B)
First i do this "test" :
for each crossroad between A and B, i make a circle of X cm (slider) of diameter and the rule is the following :
* In this circle, the future movement of my A curve must be at Z = 0
Second step :
for each next point, i have to : leave a copy on Z = 0 and rise the second one for a heigh of Y cm (slider) from the ground.
the next (W = slider to chose every each number of point, i decide to do the following point) point, which is a little bit farer from the previous point, must duplicate the same height of Y ; and also be copied to Y + Y cm.
There is a Z number (slider) which is the max height possible for these points, which mean that the next point must be at this very same level except ... The third step scenario.
The purpose is to be able to have flat area, like step in a stairway.
Third step :
The grasshopper must test if the A points are between two or more "area at Z = 0". Why ?
The goal is to obtain something like screen "side view" if there are two starting points at Z = 0.
Which also mean that if there is an odd number of points, the remaining odd number must be at the top of the "stairs"
At this point of the grasshopper, we might be able to obtain, thanks to the sliders the "staircase form" regarding :
- The size of the test circle between A and B curves
- The "footstep" of each points (height)
- The number of points before a "copy of the point + the next footstep rise"
- The max heigh possible for all the point off B curves
And at this moment i have a new problem in my logic. You will get my idea, but it might be wrong as well...
Therefore, and after that, we should be able to link every point by a straight line.
To fillet with P (angle) a line with the following one
To join all the line of a same B curve
To cut it at the center of each circle at Z = 0 (the crossroad of A and B)
To offset it with Q (distance)
To rise a line from the center of each circle at Z = 0
To cut the extra part of each Offset"ed" curve to get an offset curve "aligned in Z" with the original one.
To create loft the original and offset"ed" one
To extrude the surface to a distance of R
And grasshopper "should be done" because, i will duplicate it for the ceiling, reverse the form with a -Z vector to the Y value and modifie my Z in Z' to modify my max height
Could you help me ?
