Hi Daniel, you are my hero....

I will ask you to help me in these definitions that I made ... I am a beginner ...
1st wish: how can I force the circles on the edge of the Brep to collide as in solution 1?
2nd wish: how can I add a circle one after the other to fill as in solution 1?
3rd wish: how can I put the larger circles in the center and the smaller ones near the edge when I have to regularize the packaging of the circle?
hoping for your help ...

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.

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

Hi Daniel,

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

Thanks a lot,

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.

Here is the original post:

hi dear daniel:

Unfortunately, I can not simulate a few scissors with Kangaroo

Thank you for helping me in this field

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 .

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!

Hi Daniel,

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


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

Thank you Daniel for your efforts

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, 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~~

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

hi daniel,

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

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,
