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

I have manage to adapt this definition that you worked on(circle packing), o an image-field that defines the radii of the circles, but my main target is to optimize the radii for a better arrangement and population within the image-field allowing the radii to change and adapt during the simulation... some one posted in you tube a great video where they show this plus other interesting packing logic's....
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!
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

Hi Daniel,
I have a few question for you regarding stiffness tolerances for surface relaxation in Kangaroo. I'm attempting to use kangaroo as a form-finder for a cable-net clastic structure which i'm using to skin my design studio building. I'm trying to use varying degrees of stiffness in separate curve sets to create somewhat of a 'seam' definition on the surface of the processed relaxation, and was wondering if there was a better way to approach it than what I've been doing. The curve sets I am referring to are labeled as the Diagonal Tension Cables and Ramp Pressure Curves in the Script. My problem is now occuring where the circulation ramp is protruding through the relaxed skin, I need to figure out how to create a reactionary force back on the skin to push it away from the ramps. Thanks in advance, I know it sounds confusing but I taught myself Kangaroo last night, andI have a feeling its an easy fix.
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?
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?
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.

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:

Thank you!!

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?

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,
your Mand3d with complex number raised to power of 4 instead of 2, perhaps it looks like something too.
Hi everyone,
any resources about how to create spring connection between a set of boxes that represent spaces?

any suggestions about to achieve similar results as image base/fighting for space....?

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

I THOUGHT I RECOGNISED YOU!
So you know a friend of mine dave stasiuk!
btw kangaroo is absolute genius! really!
