Cool image for Bees! (and for enlight users about subject of Nodes ! ;)

Sorry I have no times for the moment manage all nodes for a years! :(

Hi James,
Do you have a link to "WaveSurf"?

For your old ProjectSurf.nod, replacing red Project node with Construct1/ProjectMP enabled the .nod to run.

- Brian

Your old paraSurf.nod has a couple of red nodes...in the copy I have.

Brian,

>> Do you have a link to "WaveSurf"? <<

"WaveSurf" is a macro. I have attached nod file to previous post, so macro can be found within.
I had not included before, because there was nothing really new here in terms of technique. It was done specifically to post to instagram, to keep the page fresh.>> Your old ProjectSurf.nod....[&]....paraSurf.nod has a couple of red nodes..<<

All these macro need to be reworked. I don't know that any of them are worthy of dissemination. I only used "WaveSurf" and "B-Hive Grid" for that matter, due to laziness.

,>> Will look at FatLines. <<

Did you get a chance to study Max's script?

Anyway, keep up the good work

James, thank you for WaveSurf macro.

I've looked at FatLines a little, and spread out, to line items, the functions shown scrunched into condensed paragraphs.

I see offset or flow, boolean union, scale1d, and still have to "decipher"/"understand" Max's code. :-)
Max is such a skilled programmer! There seems to be a lot going on...

I think that I will start converting bits of the code..., and fill in gaps in understanding...

I was inspired by this image (top) to see if I could generate a buildable structure in NE.

All the plank elements are indeed straight (ie the bow from flow to surface has been removed).
However it is not quite there yet, because the plank thickness varies. They will need to be uniform thickness to make structure fabrication viable. Anyway it is a start.

wow very cool, useful, and ambitious. I hope you figure it out. Certainly a challenge.

Cool start! :)

Wonderful job James!!

Congrats!

Hi everyone, and in particular Brian
Attached the file in which the Centroid tool
does not give the expected result ... maybe it will be
the case to consider well what this malfunction derives ...
Logically, when you have time, and if you want to do it
every tool we put at our disposal is a gift ...

have nice day to all

Hi Speedy,

For the center 16 triangles, the centroid point is being found.

The remaining 32, 4 sided closed curves are not planar. This centroid node works for planar polygons.
(The Planar command does not work on the 32, 4 sided closed curves either.)

The center of mass of half of a solid sphere is at 3/8 of the distance from the sphere's center to the hemisphere's pole, as shown by Max's cVolume2.
For a hollow hemisphere, the distance is 1/2.
https://en.wikipedia.org/wiki/Centroid
The centroid node does not work for hemispheres either.

Wolfram gives a formula for center of mass for spherical caps.
Also Wolfram gives a formula for the centroid of a quadrilateral as the midpoint of the line between the midpoints of the diagonals.
Or "The centroid of the vertices of a quadrilateral occurs at the point of intersection of the bimedians."
http://mathworld.wolfram.com/GeometricCentroid.html
(Usually I find Wolfram math difficult to understand, and do not plan on doing integrals:-)
So the centroid for quadrilaterals, (4 line segments forming a closed quad), planar or non-planar, could be easily calculated.

The closed quads could be tested for planarity (somehow), and the calculation added to the centroid node. (I think.)

Is there a MoI method to test for planarity?

- Brian

Hi All,

Here's a texture of planar quad facets. It may not look like much, but it is a significant step towards structure that may be fabricated from cnc or laser-cut flat panels from board or sheet material. A multi panel image of node circuitry can be found at: https://www.instagram.com/nodeology/

Hi all Friends
I was a few days holiday, just now ,
I see the latest news in the Forum _

Brian - Thanks for the clarifications regarding the Centroid tool

James - Congratulations on your latest work;
I found a small inaccuracy in determining the reference surface (Flow tool) in your file (DiaPlanarFaces)
at this link:
http://www.mediafire.com/file/56jgl6gvgzg5a0m/Rev-DiaPlanarFaces.zip/file

Have a nice day everyone
