Kangaroo wins at 1st ALGODeQ competition

ALGODeQ is an international competition for algorithmic design programs, held for the first time this year.

There were 190 entries from 43 countries, judged by a large panel of professors and practitioners from around the world, in a multi-stage process.

The original intent of the organisers had been to award a single Grand-Prix, with an award of 1 million Yen, but during the judging process it was decided to award multiple highest prizes in 3 separate categories.



It is a… Continue

Hi Daniel,

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

(http://www.grasshopper3d.com/group/kangaroo/forum/topics/new-origami-example

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

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,

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
