mmon.sdk ,but i herad its used in rhino5.
or example: the book grasshopper primer second edition ,page 98
i dont know what is the "doc.absolutetolerance" and where i can find about it....i dont kow it should be a class or a fuction,i tried to search the rhino4. net sdk,i cant find it ....maybe its my searching problem.
but according to the grasshopper primer, i indeed know many kind of Variables,many functions,basic structure, loops, and conditions,and what is onutil.xxxx and rhutil.xxxx.but i found all this imformation is not helpful enough to me when reading the examples downloaded from many disscussions.when i found a new variable or new funcion,i dont know where i can find the introduction about them,such as the upper coding:"doc.absolutetolerance".i tried to use the auto complete such as
dim xxxx as oncurve
xxxx. to find the class oncurve's funtions and variables ,but its too uneffcient.
-----------------------------------------------
And,i dont know the difference between the components vb script and dotnet vb script....
because i found when i type onutil. the auto complete has noting appear...and the variables declaring is not the same. in vb script dim xxxx as curve but in dotnet vb script its dim xxxx as oncurve,which is the same as the grasshopper primer teached me...but i guess.... the vb script component is just like the rhinoscript(not the same),and the dotnet vb script is more powerful than it. am i right?
------------------------------------------------
at last i dont know these.
Imports System Imports System.IO Imports System.Xml Imports System.Data Imports System.Drawing Imports System.Reflection Imports System.Collections Imports System.Windows.Forms Imports Microsoft.VisualBasic Imports System.Collections.Generic Imports System.Runtime.InteropServices
when i search google about them,the introduction about them is too professinal for me to understand......i just want to know what i can do by using them ...

sorry for disturbing you so much!!!
best regards!

cusing on dynamic sketches and prototyping. The workshop will be held in New York City during the weekend of February 19 and will be co-taught by Marius Watz (evolutionzone) and Studio Mode.
Description:The paradigm of scripting within ubiquitous modeling platforms such as Rhino or Maya allows users to generate complex form by accessing an underlying geometry engine and performing iterative functions. This paradigm is typically based on run-once execution, making it unsuitable for designing interactive or time-based behaviors. By implementing workflows that utilize Processing to create real-time software sketches, we can design dynamic systems that can act as standalone tools for parametric design, input mechanisms to feed other platforms, or processors of existing or sensor-based data sets.
This fast-paced workshop will focus on interactive parametric design strategies. Using Processing as our base platform, we will design real-time dynamic behavior systems, implement interfacing techniques for fluid use, and iteratively prototype the solutions in physical format through rapid prototyping and digital die-cutting. Through a series of focused exercises and design tasks, each attendee will build a stand-alone parametric design sketch and work through the process of prototyping, realizing a set of solutions through computer numerically controlled equipment (Makerbot “Thing-O-Matic” and KNK High-Force Cutters). An optional third workshop day is offered to those participants desiring further time to develop individual projects or lines of research. As part of a larger online infrastructure, modeLab, this workshop provides participants with continued support and knowledge to draw upon for future learning.
Interactive Parametrics was conceived through a collaboration between Studio Mode/modeLab and Marius Watz/evolutionzone.…

ny Agents are within it after each iteration and their centroid attract Agents). So, I basically came up with a small .dll where I wrote classes for Agent, ZOne, Cell and SystemSetting. I reference this .dll into my VB component but then the majority of the functions and subs that describe this system interaction are written directly in this VB component.
The system works fine, but I cannot achieve the effect of having the system to redraw after each iteration. For example :
'''////////////////////////////////////'''
Call InitializeEverything()
For i=0 to 19 'say, Iwant to run my system for 20 times
Call UpdateZones() 'updates attractor values of Zones
Call RelocateAgents() 'say, code that does all the evolutionary job
Dim agentSrf As New List (Of OnNurbsSurface) 'want to collect the surface_
representation of all agents and visualize it
For j= 0 to agents.count-1
agentSrf.Add(agents(i).MySurface() 'collect the Agent representations
Next
A=agentSrf
Next
'''////////////////////////////////////'''
So, in this case I will only see the surfaces of the agents after this last iteration. I was trying to use timer and target my VB component but I have my initialization function there as well so it just reruns everything from the very beginning. Or I tried to:
A=agentSrf
System.Threading.Thread.Sleep(5000)
but this didn't give me much either.
I'm sure that there is a relatively simple solution to that but I cannot find it.
Would you please give me your thoughts on that?
Thanks A lot,

used of 180 being for the northern hemisphere and 0 for the southern hemisphere.For the optimal tilt, to my knowledge, they are mostly based on correcting location's latitude through a single formula.TOF component is more sophisticated. It essentially replicates the Solmetric's Annual Insolation Lookup tool.What it does is that it creates a grid of points. Each point represents the calculated annual insolation on the surface (PV module, SWH collector, facade, any kind of surface) for a single tilt and azimuth angle.Each point is then elevated according to the annual insolation values. The mesh is created from that grid of points. The portion of the mesh which is the highest, represents the optimal tilt and azimuth angles. So the higher your "precision_" input is, the more points in a mesh you'll have - thus the more precise final optimal tilt and azimuth will be.For the diffuse component of the annual incident solar radiation for each point the Perez 1990 modified model is used. Direct is from classical cosine law, and Ground reflected component from Liu and Jordan (1963).So TOF component calculates the optimal tilt and azimuth based on annual incident solar radiation, not AC energy....…

n to finding a concave contour polyline (which is in general what you need). In your case each contour section contains a series of points of which you do not know the order and you need to sort them so that by connecting them you find the contour. This is fairly easy to do when the contour is convex (basically you find the average point then calculate the vectors from the average to the points and sort the vectors by angle - sorting the points by the same angle gives you the right order for the contour), but generally impossible to find uniquely when the contour is concave (PS: convex means that, for ANY 2 points inside the figure, a straight line connecting them doesn't intersect with the border curve - i.e. circles, ellipses, rectangles, triangles - concave shapes are a star, a crescent moon, an arrow, a boomerang, etc.).
The problem goes like this: given a generic list of points:
Each of these configurations for a perimeter equally fits the above:
Laurent already went for another possible solution, the stochastic approach (by subdividing the connecting lines), I slightly adjusted a few things over his solution:
namely, I added a rounding option to adjust for some weird tolerance issues (some points that should be at Y=80 were at Y=79.99998 or something) and a more straightforward solution to group them by section plane using sets logic. This, coupled with alpha shape, gives a quite good approach, still very coarse in terms of results but that depends on the sampling resolution of the field (i.e. number of height sections in which you calculate the metaballs) and sampling length of the connecting lines.

Diffraction , I left it, how it is.
For the unusual issues that comes in the image source component, so, is it something strange? But, I still have the same issues when I sets any integer component (single or multiple) in the “reflection order” of the image source component, in the “image source order” in the ray tracing component, and again, when I connect the output “Direct sound data” of Direct Sound component in the Energy Time Curve.
Do I wrong something with the integer component? I used it already in the first parts, for sets “grasshopper layers”, in the “Scene” component, but here it works. Should I start with a new file?
For the multi-object optimization, thank you for all suggestions. Yes, I red PHD thesis work of Tomas Mendez and the article “ EDT, C80 and G Driven Auditorium design” and still others. Thank you to all these articles, I decided where to focus my thesis.
I understand the potential of Multi-object optimization, and problems that I can finding without using it. Actually, in the beginning of my thesis, I tried to jet in contact with the Politecnico di Torino, but was not easy because I’m not a Politecnico student.
Here, in University of Florence (Building engineering), there isn’t a department or someone that is already familiar with these field of study, so, as you can image, for design my thesis, I can confide on online resources. So far, my Professor suggest me to begin with a Nonlinear Global optimization like Galapagos, and only after see the multi-object. In this way, step by step if something doesn’t work is easier to understand way and where something is going wrong: if are problems due to the setting of the programs, because we are not practical about these, or if there is a wrong in the simulations or in the algorithm and ect.
Do you think is a good way for go on?
Thank you very much,
Kind Regards
Giulia
