Thread Split: Some posts in this thread have been moved here

Hello All,

I found a grasshopper youtube tutorial by Wissam Wahbeh
inspired by the cathedral of St.Mary of the Assumption, San Francisco,
Designed by Pier Luigi Nervi and Pietro Belluschi.
https://www.youtube.com/watch?v=o4ufv13EZk4



Nodeeditor process has next to nothing in common with grasshopper steps shown in the video;
it was more about reproducing the end result.

Sorry seems i have not the "Mirror" node !
Your script is for the Official or Modified Elephant ?

Will be fine to have a list of existing nodes! ;)

Something like...(it's an old one)

---

Hi Pilou,

Sorry I forgot that Mirror was a new node. It can be found here

http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.335

otherwise I am using latest mod. It can be found here

Hello James
Well done James
nice definition_
I saw that, together with Karsten, you defined
a new way to handle points (multiple inputs for Polyline)
I have to do and I have not dealt with the topic ...
You can briefly let me know what you got
with Point Split node
I've seen formulas on the outbound links from the node.....
Thanks in advance for the info
Good afternoon
al

Thx!
More easy with mirror inside! ;)

Hello Al,

<<let me know what you got with Point Split node>>

The SplitPts / PointsExt pairing breaks what would be
one contiguous point array into a series of discreet arrays,
so as a consequence you get separate polylines instead of
one with linking diagonals. Try bypassing these 2 nodes to
see their effect.

<<I've seen formulas on the outbound links from the node.....>>

the inputs to PointExt (xLength, zLength) determine the points
at which to break original point arrays into series of new point arrays.

I hope this helps.
Let me know if greater clarification is necessary.

James


P.S. New Version using logic nodes for odd number generation attached to earlier post

Hi james
Thanks a lot for the info you gave me, I saw that
You have also updated the latest files.
Try to understand this method,
even if at first I do not think it's so easy-
I'm used to, with grasshopper to use data,
which may be flat or branched,
I do not know if I can fully understand the potentialities, the outputs of the
Node Split Point (x-length) - (y- length) and (z -length) and mode
in which to operate to branify them
What I understand and that each output alters the Array data in the three
components ...
Graphically, x width, depth y, z height
But how to work with math data is another music ...
Maybe you could send me some basic examples
"Very simple ", to understand the mechanism effectively
Thanks again..... and have a nice day

Hello Al,

it isn't so complicated than it looks;-)
If you have a pointarray with e.g. 40 points as an input for e.g. a curve the curve will be drawn from point to point, if the xLength is 40. But if the xLength is 10 and the zLength is 4 you will get 4 independent curves with 10 points in each curve.
It is an internal mechanism or meta information to organize point sequences. Some of the nodes can evaluate this an can process the right result. E.g. the bundle node generates this meta information automatically - for the concate nodes it is difficult to generate this data, because the inputs can have different length and the node will be used for different jobs.
If you want to have a look to this data you can use also the arraylogger ->scroll down, at the end there are the infos.

Have a look into the waveproto1.nod file



The point values in the info panel shows the changes - here you get 6 curves with each curve has 7 control points, without that, you will get one curve with 6*7=42 control points:-(

That was the problem here.

Have a nice day
Karsten

Hi All,
I'm trying to make a node that displays it's input value (numeric) for reference checking.
I started with the const node but can not workout how to get the label to display the input value.
So any pointers will be gratefully received.
Also I'm keen to use the node editor for animating mechanisms so a sequence node
to fire when a node sequence should start would be good or if there is a way to do this now
could you let me know.
Cheers
Barry

Hello Barry,

for animations the Quartz node is the right one. Regarding to your new node:
There is variable in the input and output object called "label". If you set this variable to your input value it should work.
Or post your file with new node you want to create, that I can have a look.
In the attachment you will find a very experimental animation proposal. I don't know if storing pictures with the camera node under windows work.
The camera node saves single pictures that can be glued with mencoder or ffmpeg to a video.

Have a nice day
Karsten

There was a node called Watch. I'll have to look for it...

Hello,

here is a draft for a simple helix node, that uses the standard Moi factory.

A nice day to all

The old Basic/Watch node, from an old version of nodeeditor, does not work properly in the latest version.

Hello Brian,

@Brian: that was a good info!
@Barry: I had a look and made some changes to show how the labeling works.

A nice day to all

Hi Karsten,
thanks for the watch node it will be useful when checking maths function outputs.
I can not run your animation not sure if it's the version of node editor I'm running or not ?
The thing I am looking for is a sequence type event ie: object 'A' moves then object 'B' etc
So basically 'A' at some point in it's move cycle will trigger 'B' to start and so on.
The thing that got my interest was the Bottle Feed Screw. I animated it in Blender using the
time line but could not do a Variable Pitch Screw that way so I used the node editor with the
quartz node and it worked great.
I'm off on holiday with a copy of Javascript for Dummies so you may hear from me again.
Cheers
Barry

Hi Friends
First of all . many thanks Karsten and James,
for the precise explanations and examples,
on my part I will try to penetrate, as the Poet says
"this dark forest"
I hope I can understand ....
I take the opportunity to share this
exercise, done time ago "Mandala 3D"-
Files and images at the following link: http://www.mediafire.com/file/l6otl6249cfc7hm/Mandala_3.rar
Have a Nice Weekend to all

Hello Al, Hello James,

thanks for sharing your files. For those who want to write some Poetry inside the nodeeditor, I made a text node:-)

Have a nice day
