Hi Tim

- Brian

Some of the information is not up to date...So recent forum posts may be helpful for install.
Max's site has the latest version.
An it runs just fine on MoI4Beta.

This looks like what I needed, Thanks so much.

Hi PILOU,

What is the difference between your Elephant & Max's Node editor?
Are they the same?
Your website provides the latest version of it?
Or we should go to Max's webpage?

I get kind of confused what is VF what is VO? and which version works best on MOI V 4.0?
I am using Windows.

Yes Elephant is the name of the Node Editor for Moi by Max Smirnov
It's it that i have on my site!

VO = Original English Version
VF = French Version of the Native Nodes of Elephant (but has also no native nodes but these no native are not translated)

All versions works fine with Moi.4.0

<< Or we should go to Max's webpage?
No Lastest version of Elephant is the Version modifyed by creators of nodes so many more nodes than original Elephant
and managed by James http://moi3d.com/forum/index.php?webtag=MOI&msg=9358.10
there you can download a zip NodeEditor !

But maybe Max will made soon a new version after the release of the who knows! :)

I ended up with an error!



I have downloaded "nodeeditor.zip" from: http://moi3d.com/forum/index.php?webtag=MOI&msg=9949.12 (Post number = 9949.12)
then I extracted the zip file into ...AppData\Roaming\Moi

and then I made a shortcut for it "Alt+N" and added : ​moi.ui.createDialog( 'moi://appdata/nodeeditor/index.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow );

but I ended up with an error!

What should I do?

Hi Psygorn, that error means you've got some unusual text characters inserted into the shortcut key text. Maybe if you're preparing the text in a word processor that has styles and such applied to it that is carrying along some extra stuff. Try using a plain text editor or set the document type to be plain text.

Did you get that text by selecting and copying from a web page? If so which page, maybe I can fix the page to not have fancy unicode control characters in what is supposed to be plain text for code.

Try this:

script:moi.ui.createDialog("moi://appdata/nodeeditor/index.html","resizeable,defaultWidth:680,defaultHeight:420",moi.ui.mainWindow);

- Michael

---

Is that it:



I used this piece of code for a short key:

script: if ( moi.majorVersionNumber == 3 ) { moi.ui.createDialog( 'nodeeditor/index.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow ); } else if ( moi.majorVersionNumber == 4 ) { moi.ui.createDialog( 'moi://appdata/nodeeditor/index.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow ); }

Does the above code works by omitting the term "script:" ?

I think it does work with or without it!

---

I took it from Pilou's page here: https://moiscript.weebly.com/install-elephant.html

Is there a place in which people share their nodes? Or tutorials?

---

Hi Psygorn,

re:
> Is that it:

Yup, that is what it looks like when it's running. You can right click in there to start adding nodes.

You can find tones here! ;)

Hello all,

Do we have Floor and ceiling functions in Math Node?

I mean this function: https://en.wikipedia.org/wiki/Floor_and_ceiling_functions

---

Psygorn,

Type into math node as shown

Hello James,

Thank you for your reply,

Could you help me here:

Why does it seem that the floor function doesn't work properly?



I don't think for the value of A = 117 it should display -1!

How can I get 1 for values of A from 0 to 180, and -1 for values of A from 181 to 360?

Hi,
try using the compare node.
Cheers

Psygorn,


It is working properly...given that sin(117) / 2 = -0.34, the floor value will be -1


Firstly, if working with degrees use square brackets : sin[a] because they convert degrees to radians
used by trigonometric functions.

If you imagine a point revolving around a circle, at any point the sine of the angle: sin[a]
equals the y component / radius, so regardless of the radius the result will be 0 on the horizontal axis
and 1 & -1 at top & bottom of the vertical axis respectively, and the points in-between will give a result
ranging from -1 to 1

There is a lot of better explanation of trigonometric functions online, here is the wikipedia page:

Hello James, but I think sin(117) = 0.891 even calculator says that!



I assume the value of sin is not calculated in Degree? (I think it is in Rad)

How can I get 1 for values of A from 0 to 180, and -1 for values of A from 181 to 360? in Degrees.
for example I thought if I use : 1+( 2 * floor function of (sin (a)/2)) I could have 1 for 0<a<180 and -1 for 180 <a<360

.>>If you imagine a point revolving around a circle, at any point the sine of the angle: sin[a]

and 1 & -1 at top & bottom of the vertical axis respectively, and the points in-between will give a result
ranging from -1 to 1

Luckily, I know about it! and I know if we imagine a circle and divide it by the largest horizontal segment (it's horizontal diameter) then "sin(an angle in the upper semicircle)" would be positive and "sin(an angle in the lower semicircle)" would be negative. :-)

I just don't know how to do it in Nodeeditor, How to turn all positive values of sin to 1 and negative ones to -1.

Edit: Dear James I always had struggle where t use RAD and where to use Degree!
