Dear David

I saw a video on your blog that intrigating me.

It's about Surface Distribution.

A friend of mine asked me if it's possible to calculate the paneling of an organic Srf ( let's say kind of half of a potatoe) with equilateral triangles in a geodesic way which is different from what paneling scripts in rhino when we consider surface domains that are concentrics.
He wants connected equilateral 3D triangles that may change in sizes but every  sides must stay equal.

He is looking for something near what I see on your video.

Do you think it's possible to do that in GH?

I can send you a picture of desired result if you're interested.

Thank you in advance for answering me

Best regards

Hi Daniel,

I just followed your kangaroo basics tutorial on Vimeo, to try and get to grips with Kangaroo a little bit. I'm pretty new to GH anway, so jumping straight into Kangaroo maybe be a bit stupid.

Anyway, I want to be able to create a helix, then to affect the pitch along its length, while maintaining the overal height of the helix by keeping both ends fixed, so I can have more turns closer together at one end, then have the control to start moving them apart further along it's length. I thought that maybe Kangaroo could do this easily.  Afterall it's a kind of spring that I'm after.  I don't know if there's a simpler way to do this in GH or if Kangaroo is the best way to achieve it. 

Any advice would be great

Thanks

Paul

I THOUGHT I RECOGNISED YOU!

So you know a friend of mine dave stasiuk!

btw kangaroo is absolute genius! really!

Hi Daniel, 

I'm trying to find how to deal with this problem (http://modelab.nu/?p=63) using Kangaroo. I've maked a simulation with two threads but when I try to make more threads the definition doesn't work. Have you tried this before?

Thank you in advance.

Best Regards.

Hi Daniel,

Is it possible using Kangaroo, to apply force from objects(using springs maybe) to a group of connected objects, without disturbing their hierarchy(relationship with their neighboring geometry)... these connected objects are inter-joined... the object themselves may or mayn't deform depending on the strength of force....if yes, how?

Thanks...

Hey Daniel

A bit of a random question, (non gh related). At your Shape to Fabricate presentation i believe you mentioned home-made 3d scanning your workshop's panels to see how accurate they were. Just wondering what software you used for this? 

I was gutted when i found out too late that they had reduced prices of the workshops. Yours and gregs was really fascinating!

Thanks,

Nick

Thanks dude. ive been giving it a go, really neat little program.

I created a group of mesh in Grasshopper, then I turned the "FLOOR" to true, but the meshes didn't stop at floor level. Could anyone help to see what's wrong with the meshes? This is the link to the questions and the files. Thanks!

Hi everyone,

any resources about how to create spring connection between a set of boxes that represent spaces?

Hi Daniel,

your Mand3d with complex number raised to power of 4 instead of 2, perhaps it looks like something too.

Dear Daniel,

Here is a video on vimeo that you uploaded 2 years ago:

http://vimeo.com/20287194

Could you please explain in a few words which forces and how distributed create such a tension between points.

I guesed there are 2 anchor pts on each side. And should be some sort of repulsion going on...

Couldn't make it

thank you

hi Daniel,

Hi have a propblem loading kangaroo - see error message below.

I did check that I have those to files in the library folder and both are unlocked.

Any ideas what it could be ?

many thanks,

Peter

Hi Daniel,

I`ve started to use grasshoper one week ago and I want to ask you about your reciprocal force`s diagram. How did you do it?

Hi daniel,

i have some questions about the reciprocal component and the optimization for tangency with kangaroo.

I found your example definition, but it doesn't work with my gemometry.

I want to create a reciprocal structure with an offset of 10cm (=rod diameter)

Can you explain, how the scale factor for the reciprocal component influences the quality of the result for the offset?

If i choose a small scale factor (e.g. 1.20), the max. deviation from the offset is veriy big. (9,8 cm)

If i choose a larger scale facotr (e.g. 2.00), the max. deviation from the offset is much smaller and better. (0,04 cm)

But then some points occure which are geometrically not possible. (see figure below)

Do you have any suggestions how to avoid this and to get better results?

Maybe you can have a look at my GH definition:

reciprocal_structure.gh

Thank you!!

Elisabeth

hi daniel,

I have saved the file with internalized mesh, I hope you can open it now.

reciprocal_structure.gh

yes, i think these crossing-over problems on the pictures might be related on the scale factor of the edges.

however, if i coose a smaller scaling factor, i don't have this problems, but then the max deviation from the offset is very big.

Is there another way to get a better result for the offset?

thank you,

elisabeth

Hi Daniel~~

if you don't mind asking, how to install plankton~ i have same problem with kris leese.

thx

Hi, Danil. I saw a video on vimeo that's named "Grabbing interaction & adding elements". I'm curious what's the Screen capture software?

Hi Daniel, 

I am having trouble turning a surface/mesh into a series of equal equilateral triangles.

I downloaded the latest Kangaroo but unfortunately some of the toggles have changed and whenever I open a script from these forums there are parts missing.

Can you provide me with some assistance? 

Thanks in advance!

Hi Daniel,

Is there a possible way to panel your folding origami on surface smoothly? 

(http://www.grasshopper3d.com/group/kangaroo/forum/topics/new-origam...) 

I tried using morph3D paneling tool but somehow the intersections between each pattern are overlapping and not smoothly join. 

Hello, Daniel! I did not properly open the files. Please tell me the current software version Rhinoceors 5, 2.3.1 Kangaroo and Kangaroo Physics 0.099 support these files? Thank you!

Hello, Daniel, I am trying to add a "select one point" in my C# written componet. But failed. Can you give a hint how the Grasshopper window is hidden, and the Rhino window is activated? Thanks so much .

hi dear daniel:

Unfortunately, I can not simulate a few scissors with Kangaroo

Thank you for helping me in this field

Hi Daniel, 

I am trying to integrate a simple 2d collision with Kangaroo in GHPython. in the example of the attached file, I have 5 polygons, four of which are attached by their coincident vertices. The attached polygons should move as single body and should repel the isolated polygon, which is not connected to anything. I am able to implement it in GH. I am able to implement the forces in GH and the solver in Python. However, when I try to implement the forces in GH Python, the results are buggy. Nothing happens and when I move a slider that constraint the max number of iterations, the shapes start to rotate.

Thank you.

Hi Daniel,

about planarization process where I can find some references for the theoretical and mathematical principles underpinning the simulation?

Thanks a lot,

Hello I am new to grasshopper.I am doing my thesis on minimal surfaces.

I am trying to make a scherks surface.

Could you please help me in solving the error of the script

Thanks

Hi Daniel,

I was wondering if I could get some advice on using Kangaroo 2/Rhino 5 to "shrinkwrap" geometry.  I've attached a file for your reference.

I have a created a sphere around a solid mesh. The sphere is collapsing using a zero length goal and the vertices of the mesh should be colliding with the sphere, but instead they appear to be pulling through the solid.

Any advice on how to best preserve the collision?

Thanks in advance for any help you have time to provide.

Best,

David
