how to install puffer fish plugin in grasshopper

@Ghana Ahmad  same way to install every plug-in. 

First download the Pufferfish.gha file. Then right click it and go to properties and check unblock then apply. Then either drag and drop the Pufferfish.gha onto the grasshopper canvas or in grasshopper go to File>Special Folder>Component Folder and copy the Pufferfish.gha there. After you have done either of those methods Close and reopen Rhino completely. Launch grasshopper again and you will have a pufferfish tab.

@Michael Pryor sir i did the same procedure but nothing happen

puffer fish tab not appear

Ghana Ahmad   if you did what I said it will be there. Do you understand how tabs look in GH? If it is really not there then what Rhino version are you using? What Grasshopper version are you using? Did you unblock the gha? and have you restarted rhino after installing? 

i m using rhino 5 and grasshopper (grasshopper_wip_20121030)

yes i did the same. i dont know this problem 

will you plzz mail(ghanaahmad16@gmail.com) the plugin or the software 

i need it for my academic project

Ghana Ahmad the plug in is on food4rhino, You need to be more specific. For instance I have Rhino5 SR14 (I believe pufferfish will work from SR5 and up, however some tools require SR12 atleast) and the latest grasshopper should be "0.9.0076". Are you using Mac or Windows. Pufferfish is made for Windows and it may or may not work on Mac. 

Pufferfish V1.6: Update - adds 6 new components like Twisted Box Through Surfaces and Twisted Box Through Meshes with interpolation options. Tween Mesh and Tween Surface components now have interpolation options. Some component name changes, icon changes, updates. Some components require at least Rhino 5 SR12. After installing the pufferfish1-6 gha, please close Rhino completely one time to avoid potential assembly reference errors with the "Twisted Box" components.

Pufferfish V1.6: Update - Re-uploaded Pufferfish V1.6 to fix a bug with the Point Divide Curve Target component.

Pufferfish V1.6: Update - Re-uploaded Pufferfish V1.6 to fix a bug in the corner orders of Twisted Box components that use surfaces.

Pufferfish V1.7: Update - adds 7 new components. Components from the Discrete Vectors plug-in (http://www.food4rhino.com/app/discrete-vectors) have been updated and are now a part of Pufferfish. Other minor updates and fixes. Some components require at least Rhino 5 SR12. After installing the pufferfish1-7.gha, please close Rhino completely one time to avoid potential assembly reference errors with the "Twisted Box" components.

Hi,

I would like to change the size of the twisted boxes along one curve. In this example I deconstructed the twisted boxes and moved the corners nearer to the curve. However, by scaling the boxes fit not together anymore. Is there a way to merge the corners of the boxes so that the geometry matches perfectly together?

Thank you in advance

Hi lv,

Look in the example files "Workflow" folder at the example "Pf_TwistedBoxVariableCurve"

Thank you for this awesome plugin!

Confirmed works for Rhino 6. 

Hi Michael, first thanks for the pluggin I really like it.

I just have a question, when I tween a surface i get a rectangular tween not the exactly organic shape. I have tried Patch-surface, Boundary surface and Plannar surface directly from rhino. Which surface command should I use? 

Hi martin

Surface tweens work on the untrimmed versions of surfaces. Patch, Boundary, and Planar surfaces result in trimmed surfaces. Rhinos tweensrf command will result also in the untrimmed versions. The way to go about this is to retrim the results. Grasshopper has two components for this "retrim" and "copy trim". Use one of those components on the tween surface results to copy the trim data from either one of your input surfaces. 

Thanks for your comment Michael, but I think this command will only get me the top or bottom surface form all along the tween, this for example when iam using diferent surface forms at the top and bottom. My question is because your example tween surface gets from 1 surface form to a different one in the tween proces combining it in the middle; so the tween is neither exactly the bottom nor the top surface form, but more like a combination like the squid example

Hi martin

The squid is because I used a mesh. With mesh it is easy to tween shapes like that (you can make your parts as mesh). The downside of mesh tweens is that they must have the same topology (common in blending through out must software). The downside of surface is there is no robust way to tween trimmed surfaces (even try Rhino's TweenSrf command will give you the untrimmed tweens). Especially if the trim data between multiple trims is very different. (what if one has holes and one does not  - for example ) In your case, it seems the surface edges are relatively similar. You could loft surface A edges to surface B edges and cut the tween surfaces with that loft. Or intersect the loft with the tween surfaces and make patch surfaces from the results.

Pufferfish V1.8: Update - adds 13 new components. All Tween Curve and Tween Curve on Surface components have been completely re-written and include interpolation options. New components added, most notably Scale to Area and Scale to Volume components. Many other additions, options, and outputs added to previous components. General optimizations and fixes all around. Some component rearrangements in the tabs. Some components require at least Rhino 5 SR12. After installing the pufferfish1-8.gha, please close Rhino completely one time to avoid potential assembly reference errors with the "Twisted Box" components.

Pufferfish V1.8: Update - Re-uploaded Pufferfish V1.8 to add edges and faces outputs to the Deconstruct Twisted Box. Also added an Evaluate Twisted Box component and a Twisted Box Centers component. Re-uploaded the V1.8 example files as well. 

Hi everyone!, im working on a project where im trying to define a structure for a bridge with small diameter pipes (as shown in the discrete polyline example picture) im having some trouble to make the definition to do this, i have some experience in GH but im not an expert if anyone could help me out it would be great 
Thank you!

Hi Michael,
As always you 're making great things for the community. 

I switched to Rhino 6 version and installed Pufferfish 1.8 updated version. Still i receive a loading error after launching grasshopper, and it seems that the hole "Twisted BOX'' tab is missing. Any idea ? I made sure to unblock the component file and restarted my rhino6.
If you could help that would be really great.

@Garikundesu 

I am not exactly sure what the issue could be in that case. Do you still have Rhino 5 installed? For me it works in Rhino 6 but I have both Rhino 5 and Rhino 6 installed and Rhino 6 picks it up automatically from Rhino 5. I haven't switched fully to Rhino 6 yet as it seems Rhino 6 still has many bugs they are updating frequently and Rhino 6 rhino common has methods that cant be used in Rhino 5. 

It seems like it cannot find where your grasshopper install is.

@Michael Pryor

Thanks a lot for your swift answer. 
Well, nice you brought it up. I do actually have Rhino 5 installed on my machine.

Actually the main purpose for installing rhino 6 was because i was getting exactly the same errors in Rhino 5 and that i wanted to use the hole pufferfish components.

Anyway, if you cross by this problem another time and could give me some feedback, i would be really grateful.

@Garikundesu Do you have other native Xform components like boxmorph or surfacebox? Trying to see if maybe you are missing that part of Grasshopper somehow. 

Hi Michael,

I could finally install it with success. I found the problem.
After downloading the component file, i pasted it in Rhino6>Plug-ins>Grasshopper>Components, while the software could load everything except the twisted box Tab.
Now i removed it from there and i went to paste it in Users>AppData>Roaming>Grasshopper>Libraries, and every Tab of Pufferfish is now working.

Thank you so much for the swift answers regardless of the time difference.

Cheers,  

@Garikundesu ah yes - Rhino6>Plug-ins>Grasshopper>Components is where the files that make up native grasshopper go. Libraries is for Grasshopper Plug ins.

Hi!

First I want to thank you for such a great plug in, it is great and very fun to explore.

Im an architecture student, currently doing my graduation project (Vertical City), and I have been exploring closest vector guide curves to create a skin for my building.
Im so new to grasshopper, so I just have couple questions if you have the time:)!
(Im using your example files btw) with Rhino 6 + Puffer fish 2.0
-
This is rough sketchs of what I want it to look like.

​-
here Im trying to get the vectors to start from around the building by using populate geometry instead of plane but it still starts from underneath the building instead of around it. How may I fix this ?

​-
As for here, I have changed the resolution of vector star and it still looks rough and has unorganized lines around, can this be fixed ?

​-

Thank you :)

@Fatima not really possible to tell where you are going wrong without the file and geometry.

Yes of course, sorry

Hi Michael ,

Is there a way to translate the colour together with the mesh with the mirror cut plane component from grasshopper?

I tried to use the mirror cut colours, however it only works within a list of colours and does not work as same as the plane cut. 

Regards,
Chris

I would assign one color set to each half of the mirror cut since the halves will have the same topology (you can get the halves by turning off join and using the i output.) So mirror cut first, then assign color.  

I can look into incorporating color into the mirror cut but I can't promise when that would be. There are also conditions where it seems subjective what to do (if I also mirror cut the color of the mesh what colors get assigned to new mesh faces made by the mirror cut bridging?, Do they just take some average of the color of the faces they connect with?)

I don't think any GH components which change a meshes topology (add / remove / combine mesh elements like faces and verts) currently keep track of the original mesh colors do they?

Hi Michael,

Thanks For your quick response, and developing puffer fish components 

I have managed to find a solution by using the TrimMeshPlane Component which keep the original colour of the mesh after the operation, i then mirror and join after operation is done. (bypasse the mirror cut mesh).

It seem that it does the work for now, but im not sure how this might impact me later on down the track.

Here the Results,

---------

I also tried to use the MirrorCutMesh together with the MirrorCutColour components which is not quite successful as the previous one, as it remap the whole mesh colour throughout the whole outcome. (i am wrong on how i interpolate the colour as it require to cull some colour that are cut)

It does the mirroring Mapping colour but not from the Initial Geometry, comparing both image you will understand what i mean.

------

Here the grasshopper component i used and i also attached the files in case you want to give it a try. 

As per the colour bridging condition, i think it is subjective, as it depend on the design. 

1) one condition for this could be by using the colour from the original mesh colour to define the colour of the bridging element (The offset plane colour is apply to the bridge)

2) Apply the same Mesh colour in along the bridge (Which might look ugly if their is a huge offset), for instance if it is red colour, it just translate the red colour across, it might be better to take the colour on the vertex of the mesh where it cut the plane to map onto the bridging component than averaging colour of the face

I hope this could be somehow helpful into developing the tool, as for myself i dont have much codding experience yet.

Regards,

Chris

@Christopher Leung

Well, I didnt do anythng special with the Trim Mesh With Plane component to keep the colors so guess it just does, however the mirror cut mesh uses the same method in the code, the difference is the new faces added by bridging. This tell me that adding new faces  to the mesh probably erase the color. 

"I also tried to use the MirrorCutMesh together with the MirrorCutColour components which is not quite successful as the previous one"


Well it is quite obvious why that wouldn't work, Mirror Cut Colors just cuts a list of colors at an index. There is no way that the order of your mesh verts / colors would match that cut, because a plane cuts a mesh doesn't mean it is cutting the order of its verts / colors in half.

Say you have a list of colors:

0:red

1:Blue

2:Green

3:yellow

say you mirror cut that list at index 2. you will have:

0:red

1:blue
2:blue

3:red

Now say that list of colors are associated with a mesh face

0: vert 0 = red

1: vert 1 = blue

2: vert 2 = green

3: vert 3 = yellow

But you mirror cut that face from between vert 0 and 1 to between vert 2 and 3, you will have remaining vert 0 and 3, so the mirror color of the mesh should be
0:red

1:yellow

2:yellow

3:red

Hope that makes sense. 

What I was suggesting to you before is to generate a color map always for one half of the mirror cut but apply it to both halves. This of course means generating the color map with grasshopper in the process.  

Pufferfish V2.4:  Update - 55 new components. 3 new tabs (Transform, Domain, List). New options for Equalized, Weighted, and Degree on Tween and Twisted Box components. Multi-threaded Twisted Box components for morphing and geometry filling / subtracting. Some components renamed and organized in different tab locations. Many component updates, bug fixes, code optimizations, and option additions. Please read the installation text file first that comes with this download before installing Pufferfish.

Pufferfish V2.4: Re-uploaded Pufferfish V2.4 and Pufferfish V2.4 example files to fix the Multi-Threaded "Polysurface Boolean Twisted Boxes" component which was occasionally causing Rhino 5 to crash, inadvertently it is now faster as well.
