new component "OSM 3D roof"):
2) Simplified 3D roads can be created by using the network of OSM polylines (through new component "OSM 3D road"):
3) 3D forest.Up until now, Gismo supported generating a single 3d tree whenever such tree was present in openstreetmap.org database. Now it is possible to generate 3d trees in forest areas, by randomly positioning the 3d trees (through new component "OSM 3D forest"):
4) Boolean 3d shapes.Gismo's "OSM 3D" component generates shapes as parts: for example, if a building has irregular shapes across its height, they will all be created individually. Trying to merge them with Grasshopper's "Solid Union" component can sometimes fail.New Gismo "Rhino Boolean Union" components tries to overcome this issue by using a much better Rhino version of this command.
5) Library of common GIS color palettes (gradients).A single component containing 22 of the common color palettes used in GIS applications as ArcGIS and QGIS. For example: elevation, aspect, precipitation...
6) Url to location.Thanks to idea by Alex Ng, it is possible to extract location from a link of the following map websites: Openstreetmap, google maps, bing maps, wego.here, waze:
Version 0.0.3 can be downloaded from here:

nd B) daylight autonomy for a single room. A and B are therefore the conflicting objectives, and are connected to the O of octopus component. The geometry iterated is that of a window, on one of the rooms' facades.
I have a grasshopper definition that iterates the window by changing:
1. Window height
2. Window sill height
3. Window width
4. Window position from one side of the wall
1,2,3,4 are therefore the genes. A combination of these genes is a complete window, which is the chromoshome, that i will from now on call solution. All genes are connected to the G of octopus component.
Now regarding the octopus settings, i have these questions so that i can properly calibrate the settings (mutarion rate, crossover rate etc):
1.In the beginning of the octopus simulation, how many are the random solutions generated? (By random i mean totally random, not resulting solutions from mutation or crossover of previous solutions, i am talking about the very first generation). Is this number connected to the population size? Is it 6? How is it defined by octopus? Can somebody control it?
2.The first generation finishes when the number of "individuals to be evaluated" is reached. Then octopus jumps to the second generation. To do so, it keeps a specific number of solutions of the first generation, the so called elite. What is the number of these elite? Is it elitism x population size?
3.The SPEA2 original paper describes step wise the algorithm loop. During the loop, a number of solutions is stored in the elite domain, and from that domain, a number of solutions is used for mating. There are therefore two numbers, one that defines the number of solutions to enter the elite domain, and one that defines the number of solutions to be inserted in the mating pool. In octopus i only see elitism as a setting, which i am guessing is what defines the number of solutions to enter the elite domain. Is that true? How do i define the number of solutions to be copied in the mating pool, where mutation and crossover will occur? This number should be called tournament size, but i can't seem to find it..
4.Why is it that DURING one generation, the number of "individuals to be evaluated" can decrease? Is it because octopus finds out that there are no more possible solutions? (i am using discrete values for the genes)
5.The gene of window width, represented by a grasshopper slider, has 4 possible values: 0,1,2,3. Assuming that the mutation rate is 0.5. Does this mean that mutation of the gene can happen to an extent of 0.5 x 4 = 2? Meaning that the slider position can change for 0 to 2 or from 3 to 1 etc?
6.The mutation probability is dictating whether or not a gene will be mutated, or whether or not the whole solution will be mutated? So for instance, with a mutation probability of 0.5, does it mean that 2 out of the 4 genes are going to be mutated, or 2 out of 4 solutions is going to be mutated. If its the second case, then how is mutation divided between the different genes? Meaning, which of the 4 genes is going to get mutated? Is it random? Is it for all 4 genes?
7.Crossover can occur between 2 subsequent solutions. Crossover rate dictates whether or not crossover will take place? If so, then, assuming that it was chosen for crossover to take place between 2 solutions, which of the genes are going to be exchanged. I mean how many, out of the 4 genes (height, sill height, width, position). Is it random?
8.After clarifying the previous 7 questions, i can run a simulation. Then, is there an indicative number that i can be monitoring, to see that no more generations are required? I know that a good pareto has to be short, with a lot of solutions and with a uniform distribution. But is there a specific number output somewhere, that can inform me that a good pareto has more or less been generated? If there is such indicator...
Thank you all,
i hope this can help others as well,

the pipe component .I have one curve ,but Pipe component outputs two pipes .This guide curve have two kinks . Pipe component fails at one of them .
Bug #3
I guess this bug may have been fixed .
Wish #1
I hope adding an "reverse list" option to the right-click menu .I think this would be useful (at least for myself).
Wish #2
I hope the SimplifyTree component would clear the zeros located at the end and middle of branch in condition the branches have same length.For example, I have a tree looks like :
A = {0;1;0} B = {0;1;0;1}
C = {0;1;0;0;1;0;0;0}
After simplify ,I get:
A = {1} B = {1;0;1}
C = {1;0;0;1}
And if the tree structure is something like:
A={0;0;1;0}
B={0;0;1;1}
C={0;0;1;2}
After simplify ,I get:
A={1;0}
B={1;1}
C={1;2}
But If the tree is:
A={0;0;0;0;0;0}
B={0;0;1;0;1;0}
C={0;0;1;0;2;0}
I get:
A={0;0}
B={1;1}
C={1;2}
WIsh #3
I came across conditions that there is no direct way to handle some Datatree matching problems . And now I think I find what's the problem :GH now lack the capability to make cross reference between lists/branches .For example, I have two trees ,the first one have two branches {0}&{1}, the other have three branches{0}&{1}&{2}.Now GH would do:
what I want is :
If this can come true ,I can say it would be very very very useful . I just have a coarse idea on how to do that: Like () wrap items,{} wrap branches, then [] wrap trees .
Say I have a tree [0] ,which have three brabches{0},{1},{2}. So [0]=[{0};{1};{2}] or [0]=[{0},{1},{2}]
If this is ruled, the following fomula is meanningful:
[0]=[{0}] (this means tree[0] just have one branch)
[0]=[{0;0;0};{0;0;1};{0;0;2}]
[0]=[{0;0};{0;1};{0;2}]=[{0;0;0};{0;0;1};{0;1};{0;2}]After that, Maybe we could match [{0};{1}] and [{0};{1};{2}] very easily (Longest List;Shortest List;Cross Reference) ??
I tried to explain the concept of "tree" to my friends ,but I am confuzed somewhere myself .For example ,how could we have a tree including branches {0},{0;0}and{0;0;0} at the same time??{0} should be the biggest tree trunk,and {0;0} is part of {0} .{0;0;0} is just the smallest trunk and store the least data inside .How could the biggert trucks are empty while only the smallest branches contain items ?(David drawed a datatree that tell this,remember??)
But if this idea is acceptable ,then I could make a fairy tale about tree to them :
(Long long ago...)
[0] is a tree ,[1] is a tree.
{0},{1},{0;0}.{0;1;0} are branches.
{0}=(0,1,2,3,4,5) is branch.
[0]= [{0;0;0};{0;0;1};{0;0;2] is a standard tree .
[0]=[{0;0;0};{0;0;2};{0;0;3] is a pruned tree.
[{0};{0;0};{0;0;0}] is an illegal tree .
Gh is lenient enough to allow the existence of illegal tree .
Gh is lenient enough to allow the existence of empty trees& empty branch&null items.
We can use PathMapper to transform an illegal tree into a legal one and vice versa . We can use PathMapper to do any things to tree&branch&item.
Wish #4
wish for Split List component : it would have a wrap option just like many other components.In this way , we can split a list of data at -1 .I think this would be useful .
wish #5
wish for a Preview toggle component .See picture below (it's fake).
this toggle look mostly like the boolean toggle, but it have a input param by which we can control the preview logically and smartly .
When there is no input ,we can control swith the preview with a double click action .This toggle component could control all gh geometry overriding the global setting .The link curve between toggle and target works just like the galapagos.
Wish #6
Wish for adding arc angle output to both Arc 3pt and Arc SED components.This would make things easier sometimes .
Wish #7
Many times I were puzzled that a same gh script would perform perfect if the input is single surface but buggy while the input is more than one surface .After debuging many times ,I just found that if one or two component of the script do things smarter ,this kind of bugs would never happen again !! Simply saying:we need a optional datatree match behavior. Say I have two datatree [{0;0};{0;1}] and [{0;0;0};{0;0;1};{0;0;2};{0;0;3};
{0;1;0};{0;1;1};{0;1;2};{0;1;3}] Normally {0;0} matchs {0;0;0},{0;1} matchs other branches (Longest List behavior).Now I need {0;0} matchs {0;0;0},{0;0;1},{0;0;2},{0;0;3} separately and {0;1} matchs {0;1;0};{0;1;1};{0;1;2};{0;1;3} separately .I cant describe this matching rules accurately but it's very obvious .I hope you can understand the meaning .
I remember David said once that he would not change anything about the datatree matching rules in order to avoid destroy people's production work .And that is my bottomline too .What I want is when I need one component to match the input datatree in this way ,I can switch it (just it ) into this mode (Assuming these is a "xxx mode" option in component's right-click menu ). In this way ,All the exist Gh def would not be destoryed.
PS. I am not carping but I found the DivideKink param input of Divide Curve component is useless except adding a segments output .
…
ariations, but each seems to lack the sophistication to generate a ‘zip’ that retains its general shape over the whole curve.
Basically I’m trying to understand the process behind this: http://www.schindlersalmeron.com/index.php?option=com_content&task=view&id=27&Itemid=29
Here is an image of the latest definition.
1. I draw a curve in Rhino, and then define it in grasshopper. I also define the point as the beginning of the curve.
2. I offset the curve to a specified depth, based on structural member
3. I generate a line from the point at a tangent to the curve, then rotate it a
defined angle.
4. I find the intersection between the rotated line and the offset curve. Then generate a tangential line from this new point
5. Line is rotated at the same angle as before.
6. Process repeated.
The idea is to then generate a circle of defined diameter at each of the intersection points, then find the intersection of the circles with the curves, which are then joined up with straight lines to create the ‘zip’. This would mean a lot of copy-pasting and list management that I’m not really capable of with my limited grasshopper experience.
I had tried generating points at intervals along the curve and then eventually generating lines from one line to another with a shifted listed to form the tooth angle, but it wouldn’t retain its shape over the entirety of the curve.
Does anyone have any advice for how to tighten up this definition? I imagine that I will need to delve into vb.net scripting to address the recursive nature of the process.
I fear that I’m going about this in entirely the wrong way...
Of course the next step is to flatten out the curve for CNC manufacture.
Any help would be greatly appreciated! The potential for using grasshopper in design is amazing, and I would love to gain a deeper understanding of it!…

ll the wires gone. Now you'll have to hook them up again. This is the sort of thing that gets annoying after the third time.
Problem #2. The solution in Grasshopper iterates over all objects and solves each one in turn. Of course a lot of objects depend on other objects, so it usually becomes a cascade of objects solving themselves for the benefit of other objects. It is therefore very difficult to predict the order in which objects are solved.
The root iteration is the same as the display order (back to front), but the topology of the network complicates matters greatly. If you change the topology of the network during a solution, you might end up with whole portions of the network not being solved at all, or, worse, a conflict in the topology checker that makes Grasshopper think a network is self-referencing.
Problem #3. Grasshopper caches all manner of things about a network that can be recomputed from basic principles, but take a long** time to do so. If you start to expire caches where I don't expect you to, we'll either run into null reference errors, or stale cache data, or invalid cache data. Problems like these are very difficult to track down.
Problem #4. File IO. Components get deserialized from ghx files based on their default layout. In your case, we need to solve a component before we know how many outputs it needs. This cannot be done until the file has been completely deserialized. It's a chicken and egg problem, which will result in missing wires every time you open a file.
If you want to have a flexible number of outputs on your component, I'd suggest you add a menu item to your component that will change the output list when clicked, then causes a recompute. This way you won't mess with the network topology during solutions and people don't get their connections pulled out from under them. You'll need to do quite a few things to make this work, but I'll be happy to help you out there:
- Adding menu items and menu click handlers
- Properly removing parameters from a component
- Properly adding parameters to a component
- Recording undo for parameter changes
- Writing custom settings to a ghx archive
- Reading custom settings from a ghx archive and making sure your component is compatible with the ghx layout before it tries to deserialize itself.

strictly with code (BTW: did you crossed Rubicon?).
1. See this: Imagine a curve (say a "rail") that is divided N times and then circles are created with random radii. Circle control points (9, that is) are sampled (obviously) into a DataTree where branches are the rail divisions. Let's call the control points: "start" seed points.
2. Imagine a capability ... that stores all these (the original "seed" control points) into a "parameter" and then each time that a change occurs to them (varying the x/y, on a per point on a per branch on a per plane basis[that provides the Z]) stores the "modified point" into the parameter (at the same index with the old: meaning "deleting" the old) ... and then some other code gets that data and makes curves and lofts them. Reset means: sample again the original "seed" points into that "parameter". Closing are reopening the definition has no effect: the lofted stuff is derived from the (internalized, so to speak) modified points (from the "parameter").
3. A variety of "automation" is available: for instance if you jump from branch to branch and from item to item the value of the selected point is inquired and the sliders that control the new x/y are "set" to 0,0 (meaning no change - yet) values. There's mo "store" mode: it works automatically as far as you modify points or you hit the reset button
4. This does that (only achievable with code):
5. Obviously points can been replaced with anything ... and thus ... we can individually modify items in collections ... and forget for ever attractor points and all that (OK where appropriate, he he).
I'll post 30 similar examples soon in the forthcoming mother of all threads: "GH goes (at last) interactive". Watch this space.
BTW: study the "animation" where points with index 6 are "sequentially" modified. I've added some delay in order to give you time to get the gist of the whole thingy.

6 make your surface using the two curves at top and bottom and a section. Use the sweep2 command
7 select your negative text surfaces and use the flowalongsrf command
maybe the scale of the text can be edited by the size of the surface or of the text but I bet you can figure that out! good luck!…

Just my first thoughts. That breakdown in optimization is just an example. Maybe 'sections' is an old-school way of seeing things, I just wanted to share some thoughts on the kind of content I look forward to seeing. It can be pragmatic topics, but also theoretical, and allow folks to share their projects and research. Some categories are specific, others broad. I suppose I'm interested in community building with regards to computational design. I think SmartGeometry attempted to accomplish this at some point in the past, to some degree. However their focus appears to be in the workshops and challenges.
I recall the silly flame wars that the CG industry had 20 years ago (lame). I'd avoid that, even if it meant forbidding the mention of any specific software in certain areas or in the entire forum. Which would be tricky, but the endless flame wars and silly comparisons were such a waste of everyone's time in CG.
Without dwelling on this too much yet, I think that the software specific questions belong in software specific forums. If we already had a common language for computational design, you'd just need to add the right description as a meta-tag to any Dynamo or Grasshopper forum post, and you'd be able to find analogous solutions in either forum effortlessly, right?
The Dynamo and Grasshopper forums lack design-centric content. The emphasis is generally on the tools and workflow. Computational design is hybrid in essence, it involves both design and computer programming (be it visual or textual). We could really use a forum for knowledge exchange where the expectation is that both are discussed with equal status.
I disagree that such a forum ought to exclude professional programmers. It should include professional programmers whom have an interest in design, and also include professional designers whom have an interest in computer programming, and everyone in between, and enthusiasts, and artists whom are curious about algorithms as a creative medium, and academics, and students, and etc etc. As long as there is rich content and activity on design as well, not only the computational bit, then the crowd will be diverse and we'll all have more to learn from one another.…
