points (which increases the smoothness of the medial axis, and hence the accuracy of the output mesh), spikes appear in the voronoi diagram as shown below.
For reference the point spacing along the input curve is 0.2mm, and the extension of the overlapping cells is about 8mm
I have compared this result with the only other Voronoi implementation i could find in GH which is from SmartForm. SmartForm SMART Voronoi does not produce this error, however it is exponentially slower, taking approx 11 minutes compared to 2.5 seconds for the native component.
Is this a known problem with the accuracy of the GH Voronoi implementation? I have tried this with various Units settings in the RhinoDoc, with no change.
Any ideas?
Are there any other fast + accurate Voronoi implementations out there?
example file is attached. Note that it requires SmartForm, but will show the error without it.
Thanks :)…
next level.
This Parametric Design course will provide the participants with the necessary knowledge and ability to use Grasshopper, a free visual programming plugin in Rhinoceros; you will be guided through a series of hands-on exercises that highlight NURBS modeling and its concepts. We will introduce Grasshopper as a graphical algorithm editor tightly integrated with Rhino’s 3D modeling tools. You will also learn how Rhino is used to render models for visualization, translate 3D models for prototyping, and export 3D models into 2D CAD or graphics programs.
English is the course main language.

logic in the script body. Now it works OK. Feeding all the right data required to Kangaroo is entirely trivial.
Happens now : create some "filters" about if a given cone is a classic one (suspended from a triad of high points == make triads of cables etc etc) or an inverted one (pulled from the ground == do something about that, anyway). This means find some interactive way to alter the cones data tree on a per branch basis (a slider access branches > the offset is altered > cone "type" > ...).
Just checked the P thing : it's all clear now (DeBrep).
That said I work in a smoke build on some MCAD app that does the following : when you hoover over a tool ... the underlying method is exposed and ... you can find what is where in nanoseconds.
Anders: I've looked at the Brep.Trim before posting this ... but .. well I can't get the gist of it (anyway the split loop did the job).
... If the Cutter is closed, then a connected component of the Brep that does not intersect the cutter is kept if and only if it is contained in the inside of cutter....
…
ee. That said these things (masterminded by a certain David R) are not bad at all ... but if you write code that is "supposedly" transferable (kinda) to other CAD apps ... well ... I would strongly recommend the other classic nested C# collections.
2. The HLP method is one out of many: for instance for a better approximation of the required fitted plane we can use the divide Curve method etc etc.
3. GH components use (in most of cases) methods exposed in Rhino SDK > get the thingy and start digging into the rabbit hole. Of course David did some other components as well that use "less" classic SDK methods (if at all).
4. HLP is a classic approach to count the beans in nurbs curves. Of course I could use PolyCurves and recursive explosion blah, blah ... but here we are not after segments (at least at present time). On the other hand if that was a Faceted Dome (planar Polylines) ... well getting the nodes that way it could be an overkill (this means business for V2).
5. Mastermind some plane orientation policies in order to finish(?) the @$%@$ thing. For instance: Given Plane plane, define a Plane.WorldXY at plane.Origin and section these 2 > then get the cross product (sectionVector, plane.ZAxis) for the new orientedPlane Y axis etc etc (this presupposes that any plane Z axis points "outwards": use Dot Product and a center point as apex etc etc).…
ime runs out, of unexplored planets. These masters of gravity risk their lives for the adrenaline, dodging gigantic rocks that could hit their ships crashing into planets and no hope that they can be rescued.
Requires Kangaroo and Human (and in full with Firefly).
Goal of the game
You have four minutes to get six stars and reach the goal. Or die trying.
If a satellite hits you, you will leave fired.
The game has three types of control
1 Using the keyboard (requires Firefly). 2 With an external device such as a smartphone or tablet (requires Firefly and TouchOSC app). 3 Using the mouse, from the grasshopper interface.

nd me to kill him but give him my regards anyway) is still around in BirdAir Italy ... talk with him.
3. Hope that you understand that designing the "details" means some decent MCAD app + FEA + this + that. "Fusing" this with some abstract graphic editor like GH ... is ... er ... impossible (in real-life, you know, he he ). Generative Components on the other hand may qualify but requires a lot of time in order to fully master it (approx 2-4 years).
4. FormFinder ... well ... that's utterly Academic but on the other hand ... (good luck).

My realistic (low cost) advise:
use K1/2 (especially if you are after "parametric" exploitation(s)) ... and then diversify tasks: stuff for the structural department, stuff for whom claims that he can(?) design the "details" ... whilst be in a constant contact with the membrane provider (and in fact: the contractor for doing the real thing as well)
…
y to heaven (or hell) is full of pain,frustration and tears. In plain English: if you are not totally committed (and willing to pay the heavy price) ... well ... what about forgetting all that freaky stuff? (the best option, trust me)
Note: 99% of beginners dream to learn programing in order to make geometry. But the truth is that this is the least (and rather the most insignificant) that you can achieve especially when working in teams with lot's of CAD/MCAD apps (and verticals) in the practice of tomorrow (bad news: tomorrow is already yesterday).
