I am no expert in this field; I would have to do research just like you. Maybe someone else on this forum has already done more work in this area, let's see. Or it might be you, the first one :)
This does not look like something completely at reach for someone with not much programming experience, but maybe with some guidance it could be doable.

>>Do you know other libraries that I can use with it?Sorry I would have to search for other libraries just like you.
EDIT: This link has a simple sine wave written from scratch. It might be a good start to mix with the code above and a playground to understand theory.

This is a standard mesh to nurbs conversion result: http://www.tsplines.com/j/subdtonurbs/MeshToNurbsBoatShell.png
You want to start with a proper mesh reparametrization:
http://www3.cs.stonybrook.edu/~gu/software/RiemannMapper/figures/ti...
Once you have your mesh reparametrized it's relatively easy to divide it into surfaces. That is the easiest approach but it doesn't take into account any features(creases etc)...
This illustrates a nice mesh parametrization with features.

EDIT:
Got a brief look at the Geomagic thingy... seems like it's a subd modeler (like tsplines). Creating nurbs out of subd meshes is easy cause you can basically trace back the subdivision. With Giulios help I was able to make a rough version of that process here: http://www.grasshopper3d.com/forum/topics/skeletal-mesh?commentId=2985220%3AComment%3A558193 ;
(the point is that subd meshes to nurbs are not as much challenging as mesh to nurbs).…
can be found in "C:\Documents and Settings\<user name>\Application Data\McNeel\Rhinoceros\5.0\Plug-ins\IronPython\settings\lib\rhinoscript" folder on WinXP. So could have used yours too.
RhinoCommon is a SDK and basically the power behind grasshopper and rhinoscriptsyntax functions. In fact each time you call a rhinoscriptsyntax, a RhinoCommon code gets executed.
And, yes:
import Rhino - imports RhinoCommon
import utility - enables importing utility.coercebrep() (or coerce3dpoint() coercecurve() ... so on)
Item access means an input is consisted of a single item.List access means an input is a list.Tree access means an input is consisted of a tree with data on different branches.rs.BooleanDifference requires both of it's arguments to be lists, so it would be logical to set the inputs b1 and b2 as lists. But there is one problem, that Mitch pointed out to me: it seems that python components (like grasshopper components) are "intelligent", and can distinguish whether you are inputting item, list, or tree. Setting your input as list, might disable this ability and leave you with only possible type of input (list).So honestly I do not know why in this case, setting the inputs to Lists worked - due to mentioned "intelligence" of python component, even an Item type would work.This might be a question for an experienced user, I am just a beginner.…
assume we want to format two numbers, one integer and a floating point value. The integer represents an index and it should appear inside square brackets, then we want the floating point number rounded to a maximum of 4 decimal places (but always using at least one decimal place, even if it's zero), and then, in parentheses a scientific notation representation using 8 decimal digits of the number.
So, assuming the index is 16 and the value is 47.280006208, what we are after is:
[16] 47.28 (4.72800062E+001)
To make this work, we need a formatting pattern that looks like:
[{0}] {1:0.0###} ({1:E8})
The square brackets, spaces and parenthesis are just part of the output, they have no meaning whilst formatting. Everything inside the curly brackets though will be replaced with a specific formatting of one of the values.
When using the Format component as shown above, the formatting pattern is just text data. The component knows that it is supposed to use the Format() function using the pattern text and whatever additional data is provided.
When you invoke the Format() method in an expression, you do need to make sure that the pattern is actually text:
So here the pattern needs to be encased in double quotes, otherwise it will be treated as code, rather than text.
You cannot use the formatting method in the internal expression of a number parameter, because this method returns text, whereas the number parameter is only capable of storing numbers. Any expression that you put into a number parameter had better return numbers as a result.…
e some questions.
I want to loop with a foreach loop trough a list of points do i have to make a list before or is it possible to use them coming in from a noed i set the access to list?
Also i dont understand why no plane is created. How do i need to feed the points in?
And why is c# expecting open parens in line 88 and 86?
Hope its not to much at once, probably i should try a few less steps to get the problems solved one by one, just hoped it would be easier and sometimes just a parentesis is missing or some format stuff, so maybe it is not so much i really cant say.
If anybody has the time and feels he wants to help it would be nice on the other hand i understand cause of the amount of chaotic questions.

n make it possible to Motivation generate
a variety of interesting objects, from abstract fractals to plant-like
branching structures, their modeling power is quite limited. A major
problem can be traced to the reduction of all lines to integer multiples
of the unit segment. As a result, even such a simple figure as an
isosceles right-angled triangle cannot be traced exactly, since the ratio
of its hypotenuse length to the length of a side is expressed by the irrational
number √2. Rational approximation of line length provides only
a limited solution, because the unit step must be the smallest common

√2
denominator of all line lengths in the modeled structure. Consequently,
the representation of a simple plant module, such as an internode, may
require a large number of symbols. The same argument applies to angles.
Problems become even more pronounced while simulating changes
to the modeled structure over time, since some growth functions cannot
be expressed conveniently using L-systems. Generally, it is difficult
1.10. Parametric L-systems 41
to capture continuous phenomena, since the obvious technique of discretizing
continuous values may require a large number of quantization
levels, yielding L-systems with hundreds of symbols and productions.
Consequently, model specification becomes difficult, and the mathematical
beauty of L-systems is lost.
In order to solve similar problems, Lindenmayer proposed that numerical
parameters be associated with L-system symbols [83]. He illustrated
this idea by referring to the continuous development of branching
structures and diffusion of chemical compounds in a nonbranching filament
of Anabaena catenula.
The following is an example of its application:
starting string: A
p1: A F(1)[+A][-A]
P2: F(s) F(s*R)
which I think is basically trying to say
F(s) = move forwar a step of length s > 0.

here are my questions.
1. The difference in general attractor transition is that, i only want the points are moving toward x axis, so if i just have ONE curve to distinguish, which is'nt the problem to find points location are in the right of left side of curve, but if i have TWO or THREE curves need to be distinguished, that is totally confused to me!
2. The points near curve which moved too big, how can i make it more equal?
3. I hope all the points can stay in the square boundary.
If anyone can give me some hint, i would be very appreciate with that.
thanks a lot!!
Shaun
