"How is this difference from using a sequence to control the number of iterations run? Is it just that it's open-ended?"

MeshMachine update

A minor update to the remeshing component (read about the earlier release here)

This adds the option to also scale the triangle size by distance from the boundaries:…

New collection of Kangaroo example files

I've updated the examples page for Kangaroo with a zip of over 80 definitions, organized by category, many with explanatory annotations, and covering several popular topics:

http://www.grasshopper3d.com/group/kangaroo/page/example-files

Hopefully this saves people some searching around, and makes learning to use it a little easier.

Dynamic remeshing - now with feature preservation, curvature adaptivity, and minimal surfaces

This will be incorporated into future releases of Kangaroo, but because it is so much fun to play with (not to mention useful!), I was excited to share this as a standalone component right now.

This is a tool for remeshing, as I first wrote about and demonstrated…

Hi Daniel~~

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

thx

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,

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`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,

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

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?

Hi Daniel,

(Flat_circlepacking_ikerImage.gh)

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....

here is the link:

http://www.youtube.com/watch?v=SSWudanJc7c&feature=related

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

thanks

Iker

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!
