nted" in space (at instance definition creation phase): indicates the obvious fact that if garbage in > garbage out (try it).
2. Load the GH thing. Task for you: Using Named Views locate the points of interest as described further and make a suitable view. That way you can navigate rather easily around (hope dies last).
3. Your attractors are controlled from here:
The slider in blue picks some attractor to play with. You can use this while the K2 is running.
4. Don't change anything here (think of it as a black box: who cares how it works? nobody actually):
5. Enable the other "black box": job done your real-life stuff is placed:
6. Enable the solver: your "real-life" things start to bounce around:
7. Go there are play with the slider. A different attractor yields an other solution:
8. With real-life things in place if you disable the C# ... they are instantly deleted and you are back in lines/points and the likes:
9. Either with instance definitions or Lines/points change ... er ... hmm ... these "simple" parameters and discover the truth out there:
10. Since these are a "few" and they affect the simulation with a variety of ways ... we need a "self calibrating" system: some mini big Brother that does the job for us. Kinda like applying safely the brakes when it rains (I hate ABS mind).
NOTE: the rod with springs requires some additional code ,more (that deals with NESTED instance definitions) in order to (b) bounce as a whole and at the same time (b) elongates or shrinks a bit.
More soon.

EDIT: DK2 works, not with positional tracking yet (14/09/15)
Source is here:
https://github.com/provolot/RhinoRift
Steps:
1) Download these files (also attached below):
https://github.com/provolot/oculus-grasshopper/raw/master/oculus-grasshopper_v0.4.ghx
https://github.com/provolot/oculus-grasshopper/raw/master/OpenTrackRiftGrasshopperUDP.ini
https://github.com/provolot/oculus-grasshopper/raw/master/oculus-grasshopper-test_v0.1.3dm
2) Download OpenTrack - http://ananke.laggy.pk/opentrack/, and setup/install. Once installed, double-click to open.
3) In OpenTrack, load the 'OpenTrackRiftGrasshopperUDP.ini' profile. Click the 'Start' button and move your Rift around - make sure that it looks like the Yaw/Pitch/Roll data is being sent. TX/TY/TZ will all be 0, as Oculus doesn't have absolute positioning data.
4) In Rhino, open the test 3dm. You'll notice that there are two viewports - called 'LeftEye' and 'RightEye'. These have been placed to mimic where the screens should be for the Oculus Rift --- but only when Rhino is in fullscreen mode, with the command 'Fullscreen'. The placement needs to be tweaked, but should work.
If you want to use your own model, you can load your own .3dm file in Rhino, then you can right-click on the viewport name, and go to Viewport Layout > Read from File. If you then load my test file, Rhino should open my two viewports, sized correctly, onto your model.
The placement of these viewports need to be tweaked; if you find a better viewport layout, upload an empty Rhino file with your viewports, and we can share eye-layout 'templates'!
5) In Grasshopper, open the .ghx definition. Everything that is multiple-grouped is a value that can be changed. Two things here:
- IPD: Set this and convert it to the proper units for your model.
- Left/right viewport names. In this case, leave this as-is, since you're using my example file.
6) Turn on the Grasshopper Timer, if it isn't on already.
7) In the GH definition, toggle 'SyncEyes' to be True. Then, in the left viewport, try orbiting around with the mouse. The 'RightEye' viewport should move around as well, pretty much simultaneously.
8) In OpenTrack, click 'Start', then toggle 'ReadUDP' to be True. You should see the 'OpenTrackInfo' panel fill with data that's constantly changing.
9) Move around the landscape with your camera, and when you set on a starting view that's ideal, click the triangle of the Data Dam component to 'store' the data.
10) Finally, toggle 'OculusMove' to be true. If all works correctly, both viewports should move based on the Rift's movement.
Let me know if you have any problems!
Cheers,
Dan…

hope this number will grow in future. Currently available features are:
1) Creation of 2d or 3d context for any kind of building related analysis: automatically generate the 2d/3d surrounding buildings for the location where you would like to perform visibility, solar radiation, cfd or any other type of analysis. You need some other plugin for the last three, like Ladybug. It only creates the context=surroundings! The "automatic generation" process also includes creation of the local topography (terrain) along with buildings.
2) Identification of certain 2d or 3d elements in the created context. For example: selection of all hotels, parks, hospitals, restaurants, residential buildings etc.
3) Performing direct terrain analysis (hillshading, slope, ruggedness, roughness, water flow...)
4) Creation of terrain shading masks and horizon files for further solar and photovoltaics analysis.
Gismo will be very grateful if he could get any suggestions, improvements, bug reports and testing in the following period. In case you are willing to provide any of these, the requirements, installation steps and .gh example files can be found here, here and here.
Thank you in advance !!…

what they really mean by that, as in what buttons to push, so I assume it's a Windows Path entry?
2.) Modify PATH
Add the install location on the path, this is usually: C:\Program File\IronPython 2.7
But on 64-bit Windows systems it is: C:\Program File (x86)\IronPython 2.7
As a check, open a Windows command prompt and go to a directory (which is not the above) and type:
> ipy -V PythonContext 2.7.0.40 on .NET 4.0.30319.225
Tutorial on setting a Windows environmental variable (path):
http://www.computerhope.com/issues/ch000549.htm
But this fails to point out that path contains many entries already separated by semicolons so if I merely add a new variable called "path" it's likely that I will destroy existing program function. There's no info on how to just tack on another entry, and the Windows 7 edit box doesn't even show the whole collection, but one item (!), so I copied the existing path into a text editor to see the whole collection successfully and added the C:\Program Files (x86)\IronPython 2.7 entry after an added semicolon, correcting for an Enthought page typo of no 's' on the end of "Program Files". I also checked the others and many pointed to old missing directories so I deleted those entries.
...and the test fails and "ipy" is not recognized as a command, even though the path now shows up using "path" in the Windows CMD window, that is if I copy all by right clicking and pasting the stuff into a text editor to really view it all. I can run it from the source directory just fine.
The rabbit hole was indeed deep. Using the Task Manager (control-alt-delete) to kill Explorer and then Run in the menu to restart "Explorer," along with restarting the Windows CMD window however, worked. I can now invoke Iron Python ("ipy") via command line from any directory. For the "path" I edited path in the System Variables and not the User Variables. No, you don't have to type that whole crazy line above just to test the path variable, just "ipy" (and control-Z to quite IronPython) in the CMD window invoked by typing "cmd" into the Start menu search box.
From the CMD line this step did work fine:
3.) ironpkg
Bootstrap ironpkg, which is a package install manager for binary (egg based) Python packages. Download ironpkg-1.0.0.py and type:
> ipy ironpkg-1.0.0.py --install
Now the ironpkg command should be available:
> ironpkg -h(some useful help text is displayed here)
But of course Step 4 fails, giving pages of what seem to be error messages;
C:\Users\Nik>ironpkg scipy
Traceback (most recent call last):
File "C:\Program Files (x86)\IronPython 2.7\lib\site-packages\enstaller\utils.
py", line 92, in write_data_from_url

File "C:\Program Files (x86)\IronPython 2.7\Lib\urllib2.py", line 509, in http
_response
...
Why can't I just download Numpy as a normal file and thus also have it easy for other users to install it when they use my scripts? This is just crazy and lazy. The Enthought developer has turned this into a computer game, with a missing registration link and then the last step spits out errors with utterly no information on how to fix it manually.
This Step 4 error is covered here:

he example file to this file so you can give it a try with any version of Honeybee that you're already using. The only requirement is to have OpenStudio installed as the component is using OpenStudio libraries to parse gbXML files. If you're using the latest version available on github the component is also available under WIP tab.
Why?
The main purpose of developing this component is to save time and effort for importing Revit models for energy and daylight analysis. It bothers me to see a lot of smart people spend a lot of time to just come up with solutions just to get the geometry from Revit to Honeybee for analysis. This component is not solving all the issue but is a first step forward. In an ideal world, the future version of Honeybee, which works both under DynamoBIM and Grasshopper should address this issue but that can take some time to be fully ready!
How?
To use this component you need to Export your Revit model as gbXML and then use the file path to load the file into Grasshopper. There are several resources available online on how to prepare the analytical model in Revit and export the gbXML file. Here is an image for importing the Revit 2017 sample model using the default settings. As you can see the model will be just as good as what your original gbXML file from Revit is.
What can be improved?
Well, there are several items that can be improved and they are mostly not on us. To get it started I add what I think are the 3 main shortcomings and my thoughts on how they can be addressed in the future. Feel free to add what you think needs to be added to this list in the comments section.
1. Revit analytical models and as the results gbXML files, by design, are not intended to be clean. Watch this presentation from the Autodesk University to see the logic behind this approach which in short is it doesn't matter for a large scale early stage energy model. Well, This will be quite a problem for studies that you can do with Honeybee. Included but not limited to daylight and comfort analysis.
The best solution that I can think of, until Autodesk fixes their exporter, is to use Revit Rooms and Spaces and generate a clean model from the scratch. We have already tried this approach in Revit but since the Revit API doesn't provide access to Room openings we had a very hard time to get it to work.
That's why that I opened an idea on Revit ideas to get over this issue. With your support we already have 81 votes, but it hasn't been enough to make them to consider the idea for an official review. If you haven't voted already and you think this will be a helpful feature take a moment and vote so we can have it implemented at some point in the future.
2. There is no way (that I know) to export only part of the model. The way export gbXML is set up in Revit is to export the whole model once together. As a result, if you have a huge model with 100 rooms and you want to get one of the rooms into Honeybee using this component you have to export the whole model, which can take some time, and then import them all back into Grasshopper. To partially address this issue I added an input to the component that allows you input a list of names for rooms that you're interested to be loaded into Grasshopper. You can use the name of the room/space in Revit as an input for the component.
3. The component doesn't import adjacencies, loads, schedules and HVAC systems. I wasn't able to export a gbXML file from Revit with any of this data except for the adjacency, but even if you can do that, the component currently can only import geometries and constructions. I hope we get access to 1 and so we don't have to use the xml file approach at all, but if that takes a very long time then we will add these features to the component.
Happy 2017!

le and grasshopper timer to simplify simulation control. Double click the main Kangaroo component to open this remote. There are buttons for Stop(reset), Play, Pause, and Step (moves the simulation forward one iteration).
Line-line force - allows interaction between line segments - they are treated as rigid cylinders. As with springs, there are settings for offset and rest distance, so this can be used to simulate colliding rods, and also for keeping cylinders tangent to one another (can be used for reciprocal structures).
Gear simulator - collision between curves in a plane, can be used for various mechanical simulations - cams, gears, rack and pinions etc.
Developablize force - adjusts vertices of a mesh locally, to make angles around each interior vertex sum to 2*Pi, so the mesh can be unfolded to a flat sheet without stretching.
Volume dependent pressure force - allows you to set a rest volume for a mesh instead of just a fixed pressure. When combined with Laplacian smoothing for area minimization, this can be used to optimize for CMC (constant-mean-curvature) surfaces. It will also work on open meshes.
Translation lock - maintains a fixed relationship between a pair of points. This can be used to enforce periodic boundary conditions for TPMS.
Equalize angles force - given a set of angles (defined by 3 points each), this tries to adjust them all to become equal.
Mirror symmetry force - can be used to minimize curvature variation, and optimize for higher order curve continuity. It can also be used for simulating torsional resistance in curved rods.
True minimal surface relaxation - Laplacian smoothing force now includes an option for cotangent weighting, which optimizes for zero mean curvature, unlike spring based methods, or uniform weighted Laplacian smoothing which only roughly approximate this.
Fast sphere collide - allows much faster collision detection between large numbers of spheres. By placing these spheres at the vertices, this can also be used for collision between meshes.
Force-density element - an experimental one, more on this later
Projected-force - adjusts its strength so the component of the force in a given direction stays constant.
New mesh tools:
WarpWeft - sorts the edges of a quad mesh into warp and weft directions. This can be used to assign them different stiffness in fabric form-finding.
Checkerboard - sort the faces of a mesh into 2 lists so that 2 faces of the same colour are never adjacent.
MeshDirection - sorts the vertices of a quad mesh to give it a sort of u-v directionality
Refine Strips - subdivision in one direction only - can be used to generate developable strips
Stripper - separates out the strips of quads from a larger mesh
Unroller - unfolds a quad strip to flat without stretching
MeshMap - maps points from one mesh to another (can be used together with circle-packing to generate conformal mappings)
Reciprocal structure - generates starting geometry for a reciprocal structure from any input mesh (using the Plankton mesh library *Note* If you already have the Plankton components installed, you will need to update to version 0.3.0, which is available from here)
ReMesher - adjusts the connectivity of a mesh by flipping, splitting and collapsing edges to make all edge lengths closer to a target value
Diagonalize - creates a new face for every edge of the original mesh. Can be used on quad meshes to easily convert to a diagrid.
Refine - simple non-smoothing subdivision, splitting quads into 4 quads, and triangles into 4 triangles
QuadDivide - subdivide quads by any number squared, not just powers of 4
Corners - finds the corner vertices of a quad mesh
ByParent - simple quad subdivision, keeping the output grouped by parent face.
User objects:
The download comes with an increased collection of user objects to simplify setting up common simulation types - Including a simple to use origami simulator, a reciprocal structure generator, and a tool to generate compact circle packings from a CP mesh.
General:
Geometry input now accepts polylines and straight curves.
Hinges can now be fold completely flat in both directions.
Various other minor bug fixes and speed improvements (including much faster removeDuplicatePoints/Lines components)
*****
I've not yet updated all the documentation and example files to reflect this new version, but over time I will keep posting here with new demos and explanation of all these new features. I'll try and add a few new examples each week. Vote in the comments below if there is a feature mentioned above that you're particularly keen to hear more about soon.
No doubt there are still some bugs to be discovered. If something isn't working the way you expect or want it to, please post in this forum (ideally with a description or sketch of what you think should be happening, and a clear description of what happens instead and any error messages).
There are also some more new features that weren't quite ready to make it into this release, but are on the way shortly...
Kangaroo remains completely free, for personal, academic, and commercial use. I'm always interested to hear about projects done using it, and suggestions for improvements or additions.

t defined from the discussion of radiation exchange between urban surfaces and the sky in urban heat island research (See Oke's literature list below). It will be affected by the proportion of sky visible from a given calculation point on a surface (vertical or horizontal) as a result of the obstruction of urban geometry, but it is not entirely associated with the solid angle subtended by the visible sky patch/patches.
So, I think using "geometry way" to approximate Sky View Factor is not correct. Sky View Factor calculation shall be based on the first principle defining the concept: radiation exchange between urban surface and sky hemisphere:
(image extracted from Johnson, G. T., & Watson, 1984)
Therefore, I always refer to the following "theoretical" Sky View Factors calculated at the centre of an infinitely long street canyon with different Height-to-width ratios in Oke's original paper (1981) as the ultimate benchmark to validate different methods to calculate SVF:
So, I agree with Compagnon (2004) on the method he used to calculate SVF: a simple radiation (or illuminance) simulation using a uniform sky.
The following images are the results of the workflow I built in the procedural modeling software Houdini (using its python library) according to this principle by calling Radiance to do the simulation and calculation, and the SVF values calculated for different canyon H/W ratios (shown at the bottom of each image) are very close to the values shown in Oke's paper.
H/W=0.25, SVF=0.895
H/W=1, SVF=0.447
H/W=2, SVF=0.246
It seems that the Sky View Factor calculated from the viewAnalysis component in Ladybug is not aligned with Oke's result for a given H/W ration: (GH file attached)
According to the definition shown in this component, I assume the value calculated is the percentage of visible sky which is a geometric calculation (shooting evenly distributed rays from sensor point to the sky and calculate the ratio of rays not blocked by urban geometry?), i.e solid angle subtended by visible sky patches, and it is not aligned with the original radiation exchange definition of Sky View Factor.
I'd suggest to call this geometrically calculated ratio of visible sky "Sky Exposure Factor" which is "true" to its definition and way of calculation (see the paper on Sky Exposure Factor below) so as to avoid confusion with "The Sky View Factor based on radiation exchange" as discussed in urban climate literature.
Appreciate your comments and advice!

is also takes place in own system. However, this action can be also carried out successfully by a foreign reference, if this considers the focused system as own. Hence, these two criteria are considered in my reflexions, to make your criticism handier for me.
First the question must be put up, how is it in your case? Of friendly manner you answer this question perpetually with the statement that you are not a partial of the system of the architecture.
Furthermore the question would be appropriate, whether an external reference (eg CAD) determined architecture. This can be answered with no, because determining and influencing are different things.
Because you stress now your criticism as a foreign criticism, within the architecture the assuption must be put up, that this criticism is not unusual new on the one hand (because this condition were also in other times like that, and presumably also always so remain) and further more a lack of goodwill in your criticism comes to light, which perhaps distinguishes an external reference.
Based on your critique, it would be also desirable in the system of the architecture if the academic rules become satisfyingly followed, even if this is no guarantor for good academic works. Nevertheless, there is an aspect which at least tolerates the evident lack in the Interdiziplinarität of the architecture. This is the classical and still valid determination of the architecture, presumably regulates not only the actions of the architects, but also those who want to become it.
Many who stand in your criticism (the students, as well as the teachers, ... ), live in the awareness that architecture is a profession that combines as many areas around the topic of Building, and the architect is even only one dilettante among the external specialists. In this determination dilettantism is revalued rather positively, because this state the architects enables to assess the facets of a complicated building project better and to form thereby the whole result positively. To be a good architect, you should have circumspect specialists around yourself. And exactly this knows the system of the architecture, because "THE ARCHITECT" helps himself with the logic of other systems (to repair on the one hand his own deficits), and to create an artificial complexity, which ultimately aims to be the complexity of human beeing.
Here "THE ARCHITECTS" becomes a quality-spoken, which currently seems the external reference (CAD, BIM) would like to take claim for themselves.
........
If would not thought about it, this might be helpful:http://www.amazon.com/The-Alphabet-Algorithm-Writing-Architecture/dp/0262515806/ref=sr_1_1?ie=UTF8&qid=1376920450&sr=8-1&keywords=mario+carpo"Finally, I’d like to restate my criticisms in general terms. If we are serious about moving architecture and urbanism away from purely artistic considerations and into a more rational arena, there has never been a better time than now. All of us have access to immense computational power which can be applied to problems that have been —until quite recently— intractable. But of course the garbage-in-garbage-out adage holds true; computation can be used to generate large amounts of complexity, but complexity does not equal worth. The only time when it makes sense to invoke computation in the design process is when there is some relevant data that needs to be computed" (David Rutton)I want to make it short, and just ask a few questions, and hope that the following questions are relevant also for you, and not be considered outside your system. i think that the weighting to such questions seem to be more valuable, not for the architects.1. What is wrong from a pure artistic intention?2. What is any sense in purely architectural discourse?3. strictly looked, can be determined sense generally in a purely architectural discourse?4. What is purely architectural discourse?5. What is Funktionalismus or Rationalismus without philosophical support? 6. Would not be the pure functional fulfilment empty ? 7. Would be not a critical position on the promise of purely rational algorithms applied?…
hat aren’t completely there. BIM will have to continue to evolve some more if their supporters want to get to realize the promise that still is. I can’t say much about PLM, but I would say that both BIM and PLM should be considered in future developments of GH and Rhino. David has said several times that some GH limitations regarding geometry and data structures (central to interoperability) are actually Rhino limitations. So, I wouldn’t put so much pressure on David for this, or at least I would distribute the pressure also on the core Rhino development team.
Talking about Rhino vs. GH geometry, there is one (1) wish I have: support for extrusion geometry. GH already inputs extrusion elements from Rhino, but they are converted to breps. Is not a bad thing per se. The problem is when you need to bake several breps that make the Rhino file to weight several hundred MB. When these breps are actually prismatic, extrusion-like solids, is a shame that they aren’t stored as Rhino V5’s extrusion geometry in a file of just a couple of MB (I overcame this once with an inelegant RhinoScript that wasn’t good for other people). This was one of RhinoBIM’s main arguments. We can develop a structural model made of I-beams in GH using the Extrude components. We should be able to bake them as extrusions. That would also work for urban models with thousands of prismatic massing buildings (e.g. extruded footprints). Even GH’s boxes are baked as breps! Baking boxes as extrusions could be practical for voxelated or Minecraft-like models.
(2) Collaborative network support. Maybe with worksession handling, or something that aloud project team members to work on a single definition or in external references or something alike. I know there is another Rhino limitation on this, but maybe clusters are already going in that direction?
And maybe on the plug-ins domain:
(3) Remote control panel that could be really “remote”, like from other computer or device. There is an old Android App for that, but is not only a matter of updating. I mean, it would be great to control a slider with the accelerometer of an Android phone, but to have that on an iPhone will require another development team. If GH could support networks, a remote counterpart of a RCP plug-in could be developed as a cross-platform web app. I don’t know if you can access accelerometer functionality through HTML5 already, but for now, asking a client (or an spectator or any stakeholder for that matter) to control your sliders from gestures of his/her own phone would be awesome (maybe Firefly will fill that hole?).
(4) GIS support. GH already imports .shp files. Meerkat can even access the database, but what about writing to shapefiles or generating our own with databases processed/generated in GH?
(5) SketchUp support. Not only starchitects and corporations are using GH in the AEC. There are a lot of small firms, freelancers and students interested. Most of them use SketchUp for 3D modeling (not CATIA, neither Revit). Yes, you can import/export .skp from Rhino, but if GH could support nested block at bake time (also mentioned by others), it could write .skp files with complex relations of blocks (that are called components in SketchUp) and nested groups, going beyond what Rhino can export.
(6) Read/Write other formats. There are some challenges with proprietary formats that are not completely supported by Rhino, but they’re still a lot of open formats that are relevant to the fields of GH users, like stl and ply for 3D-printing. It could be nice to write mesh colors to a ply for 3D-printing a colored prototype based on GH colors. There are others, like IGES, STEP, COLLADA, etc. and 2D, like svg, odg and pdf. Some of them could offer special formatting options like custom data that the format supports but nobody uses just because is impractical to access this from direct modeling environments (but not from visual programming).
