mes complicated, I wish there was a tool (specifically a slider) in grasshopper that when I open a complex file, I could slide back and forth between steps of actions which has been done to make the definition.
lets say we could imagine it as an Undo/Redo slider that starts from the first action till the end of composing the definition. it would be a grate tool for those who want to learn by playing around and see what happens step by step. it might be useful for others too to clearly see the steps and manage more complex systems.
and If undo and redo consumes a lot of processing power (I am not sure) I have another Idea.
The slider could preview or unpreview components and actions from step 1 to N.
but it should hide the components which are unpreviewed so I I can easily see the relation between definition and what happens in rhino view-port.
In other word, when I set the slider on the lets say step 7 , all the components which are made and used after that ( step 8 to N) should be hidden from the grasshopper definition so I could simultaneously follow the steps both in rhino view-port and grasshopper view-port.
thanks guys
cheers…
hat will be the basis of creating lamella members. In the sketch I'll use the 8 m side as U and 6 m as V. The surface is divided into a grid comprised of 1 m² squares. This step is not strictly needed but I use it to calculate the spacing in each direction for trimming.
2. Remap the UV of the surface again to generate the grid for lamella members in each direction. This grid subdivisions will be twice the size of the basic grid from step 1. Before remapping the grid I'm pretty sure I trimmed off the ends of the surface in the U direction by 1/2 the grid division distance (1 m off each end in the sketch). Repeat this for V, but in the other direction.
3. Extract the diagonals in each of the grids from step 2. Connect points 0 & 2 to form on diagonal, and 1 & 3 for the other diagonal. This will create lines for generating the lamella ribs. You'll have to dig around my definition to see how that's done...it will be very difficult for me to type that out.
4. Others probably have cleaner methods of producing the same effect. I know I certainly didn't put much effort into cleaning up the definition.

Here are links to the definition & .3dm file. I'm not sure if this will work with the latest release of GH though....

I'm not sure how much help I'll be. I haven't looked at this in a couple of years.…

ou will see all of the available components on a ribbon at once so there is no need to keep clicking drop down menus.
It's all about discoverability with GH. What if you're a beginner and don't know about the Create Facility (dbl click canvas) how can you find Extr?
Even if you hover over every component or use the drop down lists you will not see the name Extr appear anywhere.
Sure it makes sense that Extr is short for Extrude but it's also the Nick Name of Extrude to Point component
So you can easily miss the fact that one has a Distance Input verses a Point Input.
I think I made the move to Icons around about the move from version 0.5 to 0.6, possibly before. I initially thought that I would go back to text because I loved the mono chromatic look of the text but I soon realised that Icons were the way forward. The greatest benefit is speed. You don't need to digest and decipher every component (which is written 90 degrees to the norm).
I'm not saying you should move to Icons forthwith but at least consider that once you have a better knowledge and understanding of GH, Icons will set you free.
My top ten tips that I would highly recommend to anyone wanting to better themselves with GH.
1) Turn on Draw Icons
2) Turn on Draw Fancy Wires
3) Turn on Obscure Components
4) Use the Create Facility like a Command Line eg "Slider=-1<0.75<2" or "Shiftlist=-1"
5) Use Component Aliases to customise your use of the Create Facility eg giving the Point XYZ component an alias of XYZ will bring it up as the first option on the Create Facility as opposed to the other possibilities.
6) Try to answer other people's questions even if it's not relevant to your own area. By looking into solving a problem outside of your comfort zone and then posting your results it is very rewarding but it also lets you see the other approaches that get posted in a new light.
7) Take the time to understand Data/Path structures.
8) Buy a second monitor - There is nothing that can compare to real estate when working in Grasshopper.
9) Read Rajaa Issa's Essential Mathematics
10) Pick a panel in a tab on the ribbon and get to know every component inside and out and then move on. Start with the Sets Tab > List Panel…
Ladybug + Honeybee:
(Follow steps 0-4 for basic functionality and 0-9 for full functionality)
0. If you have an old version of LB+HB, download the file here (https://app.box.com/s/ds96em9l6stxpcw8kgtf)
and open it in Grasshopper to remove your old Ladybug and Honeybee version.
1. Make sure that you have a working copy of both Rhino and Grasshopper installed.
2. Open Rhino and type "Grasshopper" into the command line (without quotations). Wait for grasshopper to load.
3. Install GHPython 0.6.0.3 by downloading the file at this link (http://www.food4rhino.com/project/ghpython?ufh) and
drag the .gha file onto the Grasshopper canvas.
4. Select and drag all of the userObject files (downloaded with this instructions file) onto your Grasshopper canvas.
You should see Ladybug and Honeybee appear as tabs on the grasshopper tool bar.
(If you are reading this instruction on github you can download them from http://www.food4rhino.com/project/ladybug-honeybee)
5. Restart Rhino and Grasshopper. You now have a fully-functioning Ladybug. For Honeybee, continue to the following:
6. Install Radiance to C:\Radiance by downloading it from this link (https://github.com/NREL/Radiance/releases/download/4.2.2/radiance-4.2.2-win32.exe) and running the exe.
7. Install Daysim 4.0 for Windows to C:\DAYSIM by downloading it at this link (http://daysim.ning.com/page/download) and running the exe.
8. Install EnergyPlus 8.1 to C:\EnergyPlusV8-1-0 by going to the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/energyplus_download.cfm), making an account, going to "download older
versions of EnergyPlus, selecting 8.1 and running the exe.
9. Copy falsecolor2.exe (http://pyrat.googlecode.com/files/falsecolor2.exe) and evalglare.exe (http://www.ise.fraunhofer.de/en/downloads-englisch/software/evalglare_windows.zip/at_download/file) to C:\Radiance\bin
10. You now have a fully-working version of Ladybug + Honeybee. Get started visualizing weather data with these video tutorials (https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDXNep1O).
After I've done all the above I followed this video
https://vimeo.com/96155674
And everything works well.
…
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…
