2) The Curvature "flips"
The curvature graph component creates exactly what I need, but unfortunately it only visualizes the new curve (lets call this c1), without actually making it usable. If it were usable, I could just test for curve-curve intersections, and discontinuities in (c1). I have more or less replicated the behavior of the curvature graph component, except that my imitation is too smooth (lets call my imitation curve c2). I attached two images to demonstrate what I mean.
Is there a way to get exactly what the Curvature graph makes? How is it creating c1? Is it just a much larger sampling of points? Or does it somehow operate (calculus?) on the underlying formula of the curve (c0)?
Any guidance is hugely appreciated. …

rders:
1. Error (BC30205): "end of"-Anweisung erwartet. (line 96)
So i try to convert the Points3d to Strings:
v1 = (x(i).ToString())
or
v1 = (x(i).ToString("N10"))
With the result:
1. Conversion from type 'Point3d' to type 'String' is not valid. (line: 0)
So how can I extract a Data to compare the points and if equal is true do whatever I want. on my Linecomparescript ist works:
Ly = (y(i + 1).getlength())
Lx = (x(i).getlength())
If Lx.ToString("N10") = Ly.ToString("N10") Then i = i + 1End If
'cause there is only one Double inside.
THX for your ideas!…
ty lots as extrusions with their height depending on perimeter length. Then I added a 'Cull Duplicates' group to avoid properties that had duplicate 'Area' centroid points. That reduced the number of properties from 364 down to 331, though five of those have 'Area' values between 88 and 205, ten have values less than 500 while the average is ~1.3 million!
So the data is still suspect. Some appear to be nested inside of others? But using those 331 properties, I now find 32 that intersect the 'Zoning Districts'. But that's not the same as a list of properties that span two or more 'Zoning Districts'... Not having fun anymore. :)

ts. Ideally, I'd like to set the exact number of points populating the region, ie 211 in GH = 211 visible in rhino.
(I was able to achieve the exact number of points using populate2d instead of sdivide, but could only get this to work with a simple rectangular region)
2) After I have exactly 211 points, I'd like to populate each of the points with a block made in rhino (for example: the stick figure man seen in the view)
(One idea is that I build a dummy geometry and replace later with my block in rhino. But how do I make this change universally over the 211 points?)
…
raw a single line that intersects them all. I'm also not certain what the metric for "closest" would be if you have more than three lines all intersecting each other. What groups of three can you find here:
This is not just splitting hairs, when designing a new algorithm it is important to always figure out whether:
There is ever a case with more than one possible solution.
There is ever a case with no possible solutions.
Does the algorithm change the state of the problem while it runs, i.e. whether run order matters.

olution emerging in the architectural industry world-wide, the Department of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.
Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.…
onsidered period.
Even if the end of July for the mediterranean climate is not the best period to perform an adaptive comfort analysis (it's just a pretest to define a LB model) I want to refine the Adaptive comfort Chart (AC) by changing the external air temperature data imported from the .epw file with that of monitored data as reported here below:
Where the monitored ext air temperature are in this form (green panel below):
I have used the comfortPar component to set the following parameters:
Adaptive chart as defined by EN 15251
90% of occupants comfortable
the prevailing outdoor temperature from a weighted running mean of the last week
fully conditioned space (even if it is not properly in line with AC as already discussed)
The question is this: the AC component could correctly apply the code below if there is only a list of external temperature data for a restricted period (without indication about the limits of this period) and not for an entire year?
else: #Calculate a running mean temperature. alpha = 0.8 divisor = 1 + alpha + math.pow(alpha,2) + math.pow(alpha,3) + math.pow(alpha,4) + math.pow(alpha,5) dividend = (sum(_prevailingOutdoorTemp[-24:-1] + [_prevailingOutdoorTemp[-1]])/24) + (alpha*(sum(_prevailingOutdoorTemp[-48:-24])/24)) + (math.pow(alpha,2)*(sum(_prevailingOutdoorTemp[-72:-48])/24)) + (math.pow(alpha,3)*(sum(_prevailingOutdoorTemp[-96:-72])/24)) + (math.pow(alpha,4)*(sum(_prevailingOutdoorTemp[-120:-96])/24)) + (math.pow(alpha,5)*(sum(_prevailingOutdoorTemp[-144:-120])/24)) startingTemp = dividend/divisor if startingTemp < 10: coldTimes.append(0) outdoorTemp = _prevailingOutdoorTemp[7:] startingMean = sum(outdoorTemp[:24])/24 dailyRunMeans = [startingTemp] dailyMeans = [startingMean] prevailTemp.extend(duplicateData([startingTemp], 24)) startHour = 24
