hich are integers between 0 and 255 each) to XYZ which could be any floating point values, is as follows:
Dim factor As Double = 1.0 / 127.5 x = (colour.R * factor) - 1.0 y = (colour.G * factor) - 1.0 z = (colour.B * factor) - 1.0
So if a colour channel has the lowest value of 0, the corresponding coordinate will be -1.0. If the channel has the highest value of 255, the coordinate will be +1.0. In the case of [255,161,161] it does:
Dim factor As Double = 1.0 / 127.5x = (255 * factor) - 1.0 which equals 1.0y = (161 * factor) - 1.0 which equals 0.262745 (rounded to 6 decimal places)z = (161 * factor) - 1.0 which equals 0.262745
So the length of the vector with these xyz coordinates is:
SquareRoot of (1.0² + 0.262745² + 0.262745²) which equals 1.066803 (rounded again)
It also follows the largest possible length of a vector created this way is the Square root of 3, which roughly equals 1.732050
This conversion works both ways incidentally, so as long as you convert unitized vectors into colours you'll always get a non-clipped result.

o tutorial.
¿Por qué esta diferencia entre el componente "meshgraph desenróllese", y el mismo que puedo ver en el tutorial en VIMEO?
La misma diferencia que encuentro con otros componentes.
Es que una versión antigua de hiedra, .... o hay otro?, Que se utiliza en los tutoriales? Gracias
Hace falta que el plugin comprar?…

Vertices.Count * 3]; int[] facesizes = new int[m.Ngons.Count]; List<int> faces = new List<int>();
int j = 0; for (int i = 0; i < m.Vertices.Count; ++i) { verts[j] = m.Vertices[i].X; ++j; verts[j] = m.Vertices[i].Y; ++j; verts[j] = m.Vertices[i].Z; ++j; } for (int i = 0; i < m.Ngons.Count; ++i) { MeshNgon mngon = m.Ngons.GetNgon(i); facesizes[i] = mngon.BoundaryVertexCount; for (int j = 0; j < mngon.BoundaryVertexCount; ++j) { faces.Add(mngon[j]); } }
CarveSharp.CarveMesh cm = new CarveSharp.CarveMesh(); cm.Vertices = verts; cm.FaceIndices = faces.ToArray(); cm.FaceSizes = facesizes;
return cm; }
Going the other way should be similar, though I don't know if you need to define Mesh faces and then N-gons, or if you can just define N-gons right away and it'll take care of the Faces list for you... Haven't tried the Rhino 6 API... Not sure if you can just use the index operator on MeshNgon directly or you have to go mngon.Item[i] or whatever.
And then instead of
Rhino.Geometry.Mesh res = CarveRC.CarveOps.PerformCSG(...)
do
CarveSharp.CarveMesh res = CarveSharp.PerformCSG(CarveMeshA, CarveMeshB, CarveSharp.CSGOperations.Union);
Mesh m = res.ToRhinoMesh();
or your own CarveMesh-to-RhinoMesh function which preserves N-gons.

ncluding an error) but the method did not lend itself to many similar shapes, especially those that are not surfaces of revolution.
Here is a technique using Anemone that finds a solution by climbing up a path determined by a teensy-weensy semi-cone. These are the steps:
1) Define a small semi-cone having the desired slope.(base radius/height) The smaller the better but it does begin eating up computing power.
2) Place the cone at the start point and find the intersection with the surface. Since the cone is small, the curve of intersection is almost linear and at nearly the same slope as the cone. Move the cone to the end of the intersection curve, reorient it based on the surface normal at that point, rinse and repeat.
3) Continue until the intersection event gives a null. The loop outputs the end points of each little intersection curve, so at the end, the list is flattened and they are interpolated into a spiral.
In the code I included a calculation for the percentage difference between the min and max slopes calculated, using a neat technique by David Rutten and the results go from a few hundredths of a percent for a pretty smooth surface to 4 to 6 percent for something more topographical. YMMV.
Assuming your machine is as slow as mine, it's cool to watch the path climb up and around the surface - if it's not, you don't know what you're missing! but to speed things up, check ''Output After Last' in the Anemone End Loop.

The most popular year was 2008 (5 responses)
Note: According to Wikipedia: "The first version of Grasshopper, called Explicit History at the time, was originally publicly released in September 2007." Interesting coincidence.
The response to question #2 by those that began before 2007 (How long did it take for you to feel comfortable with designing computationally?):
- Years
- Don't remember, but it felt like a natural way to relate to cad.
- After a few projects
- A month.
Compared to some of the responses of those that began since 2007:
- A month
- A few months
- After 6 weeks
- About 8 weeks
- Within my second design project with GH
- five to six months
- after 1 years of self learning + over 2 years of multiple projects and continuous self learning = Computation skill is comfortable but Computational Design can not be comfortable, Crazy learning curve.
There is much diversity, but some patterns begin to emerge.
Looking forward to more responses!…
o it would cause troubles with unfolding and fabricating... that's why I used Extrude point component- it will give you similar result, but all surfaces are planar.. you can control extrusion direction with a tip point in rhino...
2)I changed tagging so every tube has 8 points form list A and 8 points from list B... first number of tag is a number of point within one tube... last number of the tag is order of tubes (I draw a little picture in GH, hope you'll understand)...I think original way of tagging wasn't really usefull.. but you can change tagging by yourself...
3) the definition is really messy, sorry about that, but it's just quite complicated task...
4)if you find some incorrect order of tagging, use the slider that controls Shift List component ... it will shift tagging..
5) if you won't be using this definition or find some better way, pleeeease don't tell me - I'll jump out the window :D ... it took me whole day to make it work :D
6)I can't guarantee you anything- I hope it works, but if not - at least I tried... so check everything (especially order of tags and points) twice before you fabricate it.. or print few tubes and make them paper first..
7)there is a part of original definition, that is not useful anymore.. I left it there, but you can delete it (I called it "UNUSED PARTS OF ORIGINAL FILE")
..good luck

On the other hand ... well ... we can pretend that this could be some sort of add-on dedicated for broken pieces, (and nerves if loops = a big number) he he.
Anyway:
1. If you enable the history (the yellow things) you can watch the recursion working: get a donor box and "slice" it in 2 (either via an "orthogonal" plane [the fast boxes] or a random one [the slow breps]). Then get each one and repeat until the desired "depth" of "slices" is achieved (the loops, that is). Pure recursion in terms of programming (a function does something, yields results and then calls itself to further process each result).
Double click on the C# to see the code (but don't change anything). For the record this is the function that does the main job (spot the fact that if it's not terminated it calls itself [last line]):
2. The x, xy, xyz options restrict the random plane (actually in the boxes case there's another technique used (Intervals) but never mind). For instance (case random breps) the slicing plane is defined at the brep center and using a random direction:
Vector3d dir = new Vector3d(rand.NextDouble(-1,1), rand.NextDouble(-1,1), rand.NextDouble(-1,1));
If the 3rd value is 0 then the plane's YAxis is parallel to Plane.WorldXY.ZAxis.
3. Now if the "slicing" thing was a random polyline at a random plane the pieces could be far more "elaborated" (and/or "naturally looking") ... but the thing with programming is to know(?) where/when to stop.
4. This approach could use any donor Brep (a blob for instance) or a Brep List. Notify if you want to add such an option.
5. Added some lines more for an option that allows to sample the pieces (due to the last loop) in an automated flat "layout" (it's a bit more complex than it appears on first sight).
6. The x,y restriction mode now affects the random slices as well. See what I mean:
and the same restriction using boxes:
Truth is that all that freaky stuff could be helpful for you if you had serious plans to learn C# (not something achievable without pain and tears aplenty).

mers considering extreme sports reject mainstream retailers and like to check out small stores rather of at chains plus malls. Several smaller retailers discuss trends in sports shoe sales. http://skateszone.com/
Though athletic shoes and sports stores and from doorways retailers have reported somewhat uptick in footwear sales due to the increase in extreme sports, the particular beneficiaries inside the trend are independent surf and skate niche stores.
Some West Coast surf and skate shops stated teenagers and even more youthful Generation Xers are not only rejecting traditional sports, but they're also shunning mainstream retailers and malls meant for smaller niche shops transporting hard-to-come-by brands.
Eddie Miyoshi, district manager at Atomic Garage, a 3-store chain situated in Gardena, Calif., stated the soaring recognition of skateboard footwear has boosted the retailer's total footwear business 20-thirty percent this year, rather of '95.
Skate footwear presently represent 80-90 % of Atomic Garage's shoe sales, while couple of years back, Dr. Martens and Timberland drove the retailer's footwear business.
Like many retailers, Miyoshi pointed to Airwalk since the trend's catalyst.
However, if Airwalk broadened its distribution to larger chains, which are frequently located in malls, only a few skate shoe customers adopted. Rather, many youthful males have switched for your skate shops for additional elusive brands like Etnies, Duffs, and Electricity Footwear by Circus. By refusing to market bigger retailers or sports stores, these brands are increasing their cachet among youthful consumers.
"Kids don't want stuff which have been within the shops,In . Miyoshi added.
Searching ahead, Miyoshi forecasted skate shoe sales will remain strong through spring '97 provided "the [hot] vendors don't auction other [non-particularly shop] retailers."
"Skaters and non-skaters are rebelling against mainstream retailers so on to surf and skate shops for many looks," echoed Mark Richards, co-online sources Val Surf, a 3-store chain situated in North Hollywood, Calif. Soaring sales of skate footwear have driven total footwear receipts up 25 percent this year rather of '95.
"The quantity of that increase might be connected while using exposure of maximum games? I am unsure. [Skate footwear] may also be actually the think about the moment,In . Richards acknowledged. And in relation to getting this right look, youthful customers can be very picky.
"Skateboard footwear is a huge category for people, but we're not able to own the brands, Etnies, Duffs, Electricity and Nice, simply because they won't sell us," stated Mark Anderson, buyer at Chick's Sports, a six-store chain in Covina, Calif. "We have people coming every single day requesting them." Consequently, skate footwear have consistently ongoing to obtain about 5 % of Chick's overall footwear business. http://skateszone.com/the-top-8-best-skateboards-for-beginners-reviews-2017/
Nonetheless, some outdoors, niche sports and sports retailers are noting the growing recognition and coverage of maximum sports will receive a modest impact on footwear sales. Trailrunning footwear and approach/outdoors crosstrainers will be the two groups benefiting the very best inside the recognition. Like the skate shoe business, some retailers realize that styling instead of function frequently drives sales of individuals footwear.
"At this time the merchandise is a lot more visual than function," stated Chet James, gm of Super Jock 'N Jill, Dallas, speaking about trailrunning footwear. Still, James noted the current hype over adventure sports helps draw more customer traffic. "The marketing campaigns and media help bring growing figures of people in, nonetheless they frequently occasions day an issue that increases results on their own account,Inch he conceded.
John Wilkinson, executive vp inside the 85-store chain Track 'N Trail, Eldorado Hillsides, Calif., stated the shop has "seen some activity in approach footwear," but he requested the amount of consumers depend in it commercially sport. And, instead of accelerating total footwear business, Wilkinson speculated elevated sales of approach footwear and trailrunners are gnawing away at traditional hiking shoe and boot volume.
But Dan Bazinet, president of Overland Exchanging, a 34-store chain situated in Westford, Mass., believes the company-new looks have breathed existence for the wilting hiking boot category. "[Approach-type footwear] don't represent the lion's participate the hiking market, nonetheless they have elevated the hiking business and provided us extra sales," Bazinet stated.
He designated Timberland's Treeline Series and Rockport's Leadville line as strong performers. Unsurprisingly, he noted the company-new looks are attractive to youthful consumer base than traditional hikers.
For that month of June, sales of men's hikers were up 49 percent at Overland, rather of June '95, while sales of women's hikers were up 17 % for that month. Bazinet also attributed elevated sales that shops walked inside the hiking business, departing that business for that specialists.
Some retailers draw a good example concerning the hiking boom of two yrs ago combined with the current extreme sport phenomenon. "Plenty of bigger chains will get a specific percent in the industry while [extreme] sports remain a fad because they are selling cost-point type gear," described Steven Carre, assistant hard goods buyer at Adventure 16, a six-store chain situated in Hillcrest.
"However individuals [true enthusiasts] will say `we need real gear' and may shown up at us. That will help us after a while. What Size Skateboard good for an 3 4 5 6 7 8 9 10 11 12 13 14 year old
