instead of ballooning outwards, just puffing upwards.
THIS WILL WORK! Creating the mesh springs is only three seconds for 200X200 and the Unary Force is still milliseconds. Only Kangaroo takes an initiation time then cycles rapidly (0.5 seconds each) and it only takes a few cycles, maybe a dozen or two.
There is considerable 3D aliasing from the 2D mesh crudeness.
Now, to best Laurent's scheme, let's double down to 400X400. First I disable Kangaroo, and the timer. The preparation takes...FOREVER....and...ever...4.6 minutes to cull the points is all, a trivial step there is likely a better strategy for than finding the ones on the inside then using those to cull duplicates from the whole collection. The springs only took 12 seconds and the forces again milliseconds.
Kangaroo, to initialize takes...after hitting the reset button to start it...over 15 minutes and counting...well 400X400 is 160K vertices and Rhino tends to bog down at 30K points...but it was done in 30 minutes. Then I enable the timer and each cycle takes...uh...it's not in any error mode but nothing is happening past a very faint first automatic cycle that shows in the mesh...yet no CPU power is being used by Rhino...well...it's simply not running...ah, well, there's just a dummy delay of another 5 minutes and then the cycles take 2.7 seconds...what a stupid delay that was not using CPU power.
Now that it's cycling, can I change the stiffness in real time, usually I can...well, no, I seem to be back in the 5 minute delay, but not the 30 minutes interface-locking one...still waiting. Here is a 1/4 scale height model of the above output:
Time's up, life goes on. The aliasing and slow speed make it unworkable except for little logos or something. Some math and parallel processing are needed?

= desired n-gon sides)
here are effects :
blue = convex hull of all points
red = section of mesh
white = desired polyline
initial 12 random points
after relaxation
I think that you should not care about points that are out of optimized curve... this polyline is good approximation, it takes care about all section points, not only those on convex hull curve. …
? do i have to implent it in the rma.opennurbs?
Is it possible to have a custom declaration region for alls vb scripts?
with best regards
Michael Sprinzl
ok i solved the problem....
to build your own custom objects which can be communicating between different VB components:
1. build a classlibary in vb.net like this:
Public Class FEM_element
' Fields
Public Material As Integer
Public Element_nummer As Integer
'Methods
Public Sub New(ByVal i_Material As Integer, ByVal i_Element_nummer As Integer)
Material = i_Material
Element_nummer = i_Element_nummer
End Sub
and save it to the Grasshopperplugin folder!!! as xxx.dll dammm it took me 2 hours to find out.
2. Put 2 VB components on the Grasshopper gui
and attach the xxx.dll with the Referenced Assemblies tool
3. vb component 1:
Dim aa As New FEM_element
aa.Element_nummer = 1122
aa.Material = 12
a = aa
End Sub
vb component 2:
Dim aa As New FEM_element
aa = x
print(aa.Element_nummer)
print (aa.Material)
4. finito bandito .... you now have your own custom type connections ....lol…

hopper no requiere de conocimientos de programación o scripting para permitir al diseñador trabajar de forma generativa y paramétrica. No son necesarios conocimientos previos de Grasshopper pero sí de Rhino a nivel básico.
Controlmad es Centro Formador Autorizado Rhinoceros y Rhino fab Studio.
Nuestros profesores son Instructores Autorizados Rhinoceros con experiencia universitaria, nacional e internacional.
El curso y los ejercicios a desarrollar están enfocados a diseñadores, arquitectos, ingenieros y estudiantes.
En este curso introductorio el alumno se familiarizará con términos básicos de la estructura de Grasshopper, como “listas de datos”, “dominios”, “estructuras en árbol”, etc.
Es un curso de 18 horas, con el que se pretende entrar en la lógica de trabajo de Grasshopper mediante diversos ejercicios, de forma que el alumno sea capaz posteriormente de desarrollar sus propias gramáticas, con la confianza que da comprender los términos básicos de programación sobre los que se apoya todo el sistema de trabajo de Grasshopper.Para este curso no son necesarios conocimientos previos de Grasshopper, pero sí de Rhino (a nivel básico).
También se vincula el programa con la impresión 3D aprendiendo a exportar archivos desde Grasshopper con los requisitos mínimos de impresión 3D. Se realizará una demo de impresión en el aula.
El primer día del curso se le facilita al alumno un manual-tutorial con los ejercicios a realizar, en PDF.
A la finalización del curso, y siempre que el alumno haya asistido al 80% de las clases, se le otorgará un diploma oficial acreditativo del curso.

opening a simple file with 30 curves being lofted took like 2 minutes to complete and Rhino crashed afterwards saying:"Windows is out of memory and Rhino will close after you click ok."evethough I still had 7GB of free physical memory and my page file is set also to 16 GB just to be shure...I then switched to Rhino 5.0 Version 5 SR14 64-bit (5.14.522.8390, 05/22/2017) which also had big problems to display the lofted surface. It was unresponsive after loading the file for a minute and a half and then it normally displayed the lofted surface. Every move of camera takes at least 10 seconds to update, but at least it runs. GH profiler says the loft took only 12 ms (90%).
So I'm suspected my graphics card, because the Windows are just three weeks from a clean install. I've also updated my Graphics Driver from the stock Windows one to Intel HD one, but nothing changed.Is there something I'm missing??? What can I try next?My specs:CPU: i5-3320M @ 2.60 GHzRAM: 16 GBGPU: Intel HD Graphics 4000, driver: 07.04. 2017, version 10.18.10.4653

he sunPath component works. For example if you want to simulate the hours from 8 to 16 it means you want 8 hours from 8 to 9, from 9 to 10,.... from 15 to 16 (8 hours duration period) so you get from the sunPath component (using default timeStep 1) the 9 sun position/vectors 8 9 10 11 12 13 14 15 16 (in the image the yellow suns). The things is that if you ask for a smaller timeStep for example 3 = 20 mins then the additional sun position (in the image the orange suns) are added also after the time limit of h16 so probably when you don't want/need. I understand that when you input a time period there is the ambiguity if the hours are the just 9 (the 9 inputs) or the 8 hours included between pairs of hours, but I would make in a way that it is possible to chose if the extra timeStep after the last hour are added or not. Thank you for your comments.

rom a few pieces until all of the pieces are in place. You could also, theoretically, modify the form of the base, high, etc.
To do this I started making three pieces (all triangular) of different sizes... and then I stablished that there is going to be a bigger concentration of bigger pieces on the first third of the building, a bigger concentration of medium pieces on the second third and a bigger concentration of small pieces on the last third. I did this by rotating the pieces a number of times accordingly to a percentage.. the funny thing is that it works most of the times, but it doesn't work if the base of the building has 3, 8, 12, 18 or 20 sides (20 being the higher number on the number slider).. maybe there is a way to solve this with lists that I am not using????
My second problem is that I want to rotate each floor of the building separetly using a range... the thing is, I cannot make it work, because it rotates each triangle and not the whole floor... maybe there is a way of making groups or changing the list definition, but I'm not getting there.... I tried working with planes, but it is even more difficult to make the whole thing work...
I'm attaching the grasshopper documment and a couple of pictures so you can get my idea....…
