Hi All,

An experiment showing a field of columns effected by twin attractors.
See attached.

Hi Friends
The holidays are over, we are back
In the real world ........ I hope everything is fine
for you all-
- I tried to accomplish this exercise, relative
at SuperEllipse, but applying the concept
not only to the curve 2d, but the 3d shape
In such a way as to have a shape transition
starting from an Astriod, passing through an Octahedron , a Sphere, etc etc,
to arrive on acubic smooth Shape -
I also added a variation, in which ,
varying the parameters that govern the domain of the form
in x, y, z, in the final assembly, an interesting explosion is created
of the main form-
I hope the subject is Vs interest ,
for those interested, find the material here :http://www.mediafire.com/file/1s70l89err5gyda/SuperEllipse_3d.rar
Wellcome back at all
best

Hi, Speedy, welcome back.
I've tried running Basic 3d SuperEllipse.nod with the default settings but nothing happened.
Is there a special way of using it?
Mike.

Hi Mike
The way you use it and scroll through the slider that will select you
the default inputs, for the different form to be obtained, and wanting ,
You can vary the value sliders, rx, ry, rz ...
Follow the pictures posted
I tried to reload the file sent ....
For me it's all Ok-
I do not know what the problem is, one should know if
Others have had your problems
Have a nice day

The superellipse node worked fine with the latest nodeeditmod
- Brian

Brian - that's 0.93?

---

Yes

---

Looked a bit more carefully - didn't have the Mirror node.
Now working fine.

Has the Points/MathPts node been fully implemented yet?

I ask because it seems to me that variables B & C have not been implemented in that way that variable A has been.
EDIT: Or perhaps the use of variables has not been implemented for X and Z?

I was trying to make a simple nod to produce Brian's HyperbolicParaboloid2:
_FxGraph3D a*(u+v);b*(u-v);u*v;-1;1;-1;1;50;50;1.618;1;0;UV see post 6447.73 and couldn't get it to work using variables A, B & C in Points/MathPts as below.



when I deleted variables B & C (shown below) it worked



Here's the working nod:

Nice node Mike.

I took a very brief look, and see symmetry in the code, for the a,b,c,d, so have no idea.
Will look longer tonight, if someone else does not figure it out first.
The a, b, c, d have to be sequentially added in to the node... (?)

- Brian

By the way, The Pringle reconstituted potato chip has the hyperbolic paraboloid shape, with some sort of rounding.
No Pringle measurements were made, just stuck in 1.618 as a "golden" ratio, as a guess. (Some talk on Alibre forum.)
(Trim can be done with circle, ellipse, etc.)
(The polylines are linear.)

Hi Mike,

>>I ask because it seems to me that variables B & C have not been implemented in that way that variable A has been.
EDIT: Or perhaps the use of variables has not been implemented for X and Z?<<

The issue is not with X,Y or Z implementation but with variable fields A,B & C (not just B & C).


It is best to wire in all node inputs with Widget or Basic/Const nodes where possible,
as a few node do not register direct numerical inputs, despite having fields for doing so.

And besides, it makes the node circuitry more legible.

Hi Karsten and Friends
Well done Karsten......
The new Twist Nod works fine,
coupled with Flow Nod by interesting results, the
Those interested find this link ,my test:http://www.mediafire.com/file/vuuf2yk4d35c5pj/Twist_Test.rar
Have a nice day to all

Thanks, James.
Hopefully in time the entry fields will be fully operational thus removing a source of confusion for those wanting to write a stripped down nod.
In the meanwhile the work around is, as you pointed out, one that has benefits.
Mike.

Brian, as an exercise I've made a nod based on the 4 variants that you posted for Hyperbolic Paraboloids.
The nod uses the same variable as you posted using discrete inputs to Points/MathPts as James advised and displays all four variants together.
The slider is limited to one decimal place so to get a value of A of 1.618 (as you had) it is necessary the disconnect the slider and to enter 1.618 directly into the A input field in Points/MathPts - which does work as expected (B and C don't).
I did think of making the spacing of the outputs on the screen automatic but concluded that it would make a very confusing nod so I opted to make the spacing manually adjustable via a knob.
The output is 4 solids through the use of Construct/Extrude with a distance of 0.01mm.
Please check that the outputs look right to you.
Thanks, Mike.

Hi, James.

Seems to me that the A input field does work in Points/MathPts - as long as there is nothing connected to the A, uh, input button.

Mike.

Visually, the node looks good.

In the Info panel, the slider "digits" can be increased. The slider can display at most 2 decimal digits, in the current range.
So digits could be increased to 3, but only 2 are displayed in the slider.
It looks like the slider shows as most 2 decimal digits, with the 3rd decimal rounded to two decimal digits.

It is possible to easily edit the interface.js file so as to display more decimal digits in the slider, but I will leave it alone.
There are range limitations to the # of digits displayed, as well.

A trivial 'real world' nod to produce a printable circular funnel.
As an example I've chosen sizes to match a funnel I made some years ago to facilitate loading peppercorns into a pepper grinder.

Welcome to the Elephant
World...... Mike.
Perhaps, for such a simple object, I think that,
start with a profile, then create a revolution
is the best method ....
Maybe many less Nod ???? ...
In every case appreciable

Hello Mike,

it makes me happy to see the different aspects of the application. Especially when the results will end in real world parts. Methods and complexity will automatically increase. And used in the right place, productivity will also increase:-)

Have a nice day
Karsten

Thanks for the suggestion, Al, I'll think about it.
Mike.
