ons, variations, and "cross-breeds" of consumer electronics product designs, for example, telephones:
Or for example, to generate and populate control panels with parametric variations of knobs, dials, etc.:
I've been reading up a bit on procedural/generative modelling, shape grammars, etc. But the first basic problem I've run into, is that all the devices I'm interested in generating have filleted edges, and I've read that Grasshopper can't do that, because the FilletEdge command is not exposed in the SDK. I did read however that in Rhino 6, fillets will have history - so I wonder if that opens it up to Grasshopper at some point in the (hopefully not too far) future? Or is there some other approach that would help in generating these kind of forms in Grasshopper?
I guess most people doing this kind of generative modelling for CG/games would use Houdini or 3DS Max, but I want to be able to actually build some of these things with 3D printing/CNC, so I think I would be better off in the NURBS/solids world? I also looked at Solidworks/Inventor, which do very well with parametric fillets, but it seems like it would be difficult to get them to do the kind of generative stuff that Grasshopper can do, fooling around with Excel spreadsheets and formulas. Unless I missed some kind of Grasshopper-like plugin or scripting system for them?
Anyway, comments appreciated. I can imagine Grasshopper being quite useful for industrial design concept exploration, surprised that I haven't seen more of it...

onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

een them. I made so drawing to explain the shape I wannt to givve to my object.
I don't really nead 3D because my object will be print in a laser cut. So I just nead the drawing of the pieces.
I give you the GH and the rhino. For the moment someone help me to build one clip. But there are bugs on it when I change parameters.

nteraction in the design of an enclosed volume.
Revolutions have occurred through architectural history and vary widely in terms of design methods and fabrication techniques. Focusing on inspiring natural form‐finding techniques, AA Athens VS works towards producing a large‐scale interactive prototype that alters in real‐time the perception of interior space.
Technology and architecture are coupled for the third year in Athens with a novel agenda of transforming an enclosed area and creating internal contrasting city‐life characteristics that transcend the local conditions. In collaboration with the National Technical University of Athens, Cipher City: Revolutions explores participatory design and active engagement modeling and continues building novel prototypes upon horizontal planes.
The toolset includes mainly ‐among others‐ Rhino Grasshopper, Processing and Arduino platforms. With the completion of the Programme participants receive the AA Visiting School Certificate. In 2013, the design agenda of AA Athens will connect with the agenda of AA Greece VS in the city of Patras. Participation in both Programmes will allow for a more extensive learning experience through additional tools like Autodesk Maya, Autodesk 3D Studio Max and more.
Discounts
The AA offers several discount options for participants wishing to apply as a group or participants wishing to apply for both AA Athens and AA Greece Visiting Schools:
1. Standard application
The AA Visiting School requires a fee of £600 per participant, which includes a £60 Visiting Membership. If you are already a member, the total fee will be reduced automatically by £60 by the online payment system. Fees are non-refundable.
2. Group registration
For group applications, there will be a range of discounts depending on the number of people in the group. The discounted fee will be applied to each individual in the group.
1. 3-6 people group: £60 (AA Membership fee) + 540*0.75 = £465 (25 %)
2. 6-15 people group: £60 + 540*0.70 = £438 (30%)
3. more than 15 people group: £60 + 540*0.65 = £411 (35%)
3. Participants attending AA Greece VS and AA Athens VS | 40% discount
For people wishing to attend both AA Greece VS and AA Athens VS, a discount of 40% will be made for each participant. (The participant will pay the £60 membership fee only once.)
£60 (AA Membership fee) + (540*0.60)*2 = £708

and the degree of your periodic curve is 3, then start picking one point to the left. If the degree is 5, start pickin 2 points to the left, etc.
Every curve has a domain. A domain is a numeric range defined by two numbers (a lower and an upper bound). Within the domain, the curve exists and the equations which govern the geometry of the curve yield decent answers. The lower limit represents the start of the curve, the upper limit the end of the curve. Everywhere in between you can evaluate curve properties (position, tangency, curvature and any other derivatives, tension, torsion etc. etc.).
There is no significance attached to the actual numbers in a domain. All that is required is that the lower limit is smaller than the upper limit. When we create curves in Rhino we tend to pick domains that represent the length of a curve, but if you scale a curve afterwards you change the length, but not the domain.
Curve parameters are numbers inside this domain. Basically, think of all curves as finite line segments which can be bend, kinked and stretched in 3D space. Curve parameters are locations on the 1-dimensional space that is defined by the line. The curve equations are all about converting those one-dimensional parameters into three-dimensional points and vectors.
Like I said, the mathematics are pretty involved and periodic curves are more difficult still.

p; 3D Urban ModelingOn the topography subject I get the next message: "One or more boundaries may be outside the bounds of the topo dataset" I'm not sure if it's the .IMG file I'm loading since I found so many IMG files nearing my polyline area (Miami Lat:26 Lon:-81 aprox.) or maybe my polygon doesn't match the topo area? I have no idea why it isn't working :(On the Shapefile subject, haven't been able to find a Building Height SHP File, so far have downloaded around 8 SHP files which only contain Polylines, my solution is to meanwhile randomize Z heights, but of course this data is not "technically" correct.P.S.: I've already tried all example links and also the ones posted by you and Benjamin in this video.Been strugling last few days, hope you can help me, thanks in advance!!…
component in GH for a project im working on. as part of that component I want to dynamic show text the rhino viewport but I don't want to have to return a value that I then plug into the "text tag 3d" component. I want to build a similar method into my custom component.
therein lies my problem. I haven't yet figured out how to get my vb code to produce text.
my latest attempt looks a little something like this.
Dim TestPoint3D As New rhino.Geometry.Point3d(0, 0, 0) Dim TestVect As New rhino.Geometry.Vector3d(0, 0, 1) Dim TestPlane As New plane(TestPoint3D, TestVect) Dim TestText As New display.text3d("bob", TestPlane, 10) ListItem = TestPlane TextItem = TestText
but I get nothing out of it.
latest theory is to try using "Draw3dText Method (Text3d, Color)" but this is where ive hit a wall
if I understand how this works than I would think I would code this
Dim TestText As New Rhino.Display.DisplayPipline.Draw3dText( text here, and color here)
but the hint that im getting after "DisplayPipline" doesnt show a "Draw3dText" method?
so im confused?
again my overall goal is to get text to display in the viewport directly through my component
any thoughts or ideas, or if im even in the ballpark on this one would be helpful.
thanks!…
