@ Kasten :
Yep excellent animation : like with origami paper in reality!

@Speedy
use http://www.videolan.org/vlc/ ;)

I will try your nodes as soon as possible!

Hello Pilou,

>>>>Yep excellent animation : like with origami paper in reality!
The animation is made with MoI and the nodeeditor:-) The camera node makes single pictures with MoI's render function for each quartz node step. After that, you have e.g. 500 pngs. Then ffmpeg or mencoder and the video is finished. Unfinished: automatic start of ffmpeg and choosing the output directory for the single pictures. But for a quick animation it's okay. When I solved this problems, I will post it. (Maybe it is better to post the problem;-)

Hello Al,

please explain, which vector math functions we need - add, substract, cross_product, scale, scalar product, coordinate transformation, rotate by axis and how would they be used to solve that problem?
Great Job!

A nice day to all
Karsten

p.s.: Sorry that the video is not working for you - I use Linux for scripting (here it works), but as Pilou mentioned, VLC should do it.

Hello Karsten
If possible all the functions of Vectors :
1- Create Vector ,from Coord (xyz) ,connected to the actual node point
2-Decompose Vectot retur value of (xyz)
3-Unit Vector for x , y , z for simple placement
4-Amplitude of Vector
5-Vector between two point
6-Angle between two Vector
7-Rotate Vector on plane or on axis
8-Dot procuct
9-Cross Product
10-Line , start point , direction, Vector , and Amplitude , length
11-Measure Vector length
12-Unitize Vector
13-Reverse Vector value
14 - link with extrusion , profile along a Vector
No ask that all implements,
But the important thing it is start ...
Line, and Extrude example would be useful-

(I hope the list does not discourage you)..........

The facilitation is the ability to create oriented lines,( crease)
and subsequently to lean them to create the Movements ,
rotating or translating through simple input values
Have a nice day

Hello Al,

most of the functions are already implemented. Have a look in basicfunctions.js or in the litegraph.js (Max has thought of everything!). Only missing: wrap it in nodes. We can use pointarray as the base. Set scale to 0 it's a displacement vector:-). Scale to 1 it's a local vector ->arraypoint (Homogeneous coordinates). You've done the vector math stuff manually with the splitPts, (chapeau - a lot of work ) but yes we should make nodes for that. It will take a while and I have to think about some details, but it's possible.
Thanks for the impressive example!

Have a nice evening
Karsten

@Karsten
Does the resolve of the concept (not the animation) can be replicated to any start number drawing of "flat" Valley (s) / Mountain(s)
Supposed that each little surface resulting are plane for the moment! :)
Difficuly will surely to take any start form of drawing!

@Al : works like a charm! Bravo for the effort!





Nodes'Image of the "white" folding example! :)

Hello My Friends
another exercise, move on and invert
which brings me back a lot through the years
..... to my childhood

Hello Karsten and Friends
Great Work with the new Vectors Nodes.......amazing
I'm starting to use them to test them ,
then , surely , you will need clarification ,
for now thank you for your commitment.
Take this opportunity to send a new test
on Fold / Unfold
Have a nice day to all

Hello Al,

thanks for sharing! I can't test it at the moment -I hope in the evening, but the pictures a very promising:-)

Have a nice day
Karsten

p.s.: Please, tell me more details about uncertainties with the vector nodes.

Cool continuation!

Hello Karsten and Friends

Doing an experiment of manipulation coordinate point
inserting a point attractor, I found out that Point Ex Node
It does not return the sorted values in order to create curves in U
or V-
Wanting to act with idx select point, I can not utomatizzare
the insertion indices
to be able to sort and group the points and have them ready for
create curves ...
I have to do it one by one?
I believe that this problem must be solved ...
We should get out put what we get
using Poin or Point Math
ie, through ConvertPoint-(set of curves)
separate curves ..
I can not add attachments
then the file is available at the link

best to all

Ps - would not hurt to add a node
Point to Point Distance .....
I hope so

---

Hello Al,

the problem is that I made the node for other things and so some meta informations (xlength,ylength and zlength) are lost between split and ext. But you don't need it. Maxs math points can do the job already.
Nevertheless I can add the meta informations also.

Have a look in the file.

Have a nice evening
Karsten

Hi Karsten,

Although in this instance the desired result could be achieved with a maths formula; there are many situations where it would be useful to insert truncation points into a point array to break it into multiple discreet point arrays for the generation of discreet curves for lofting.

Perhaps "idxSelect" could have an "TruncPt"mode and Curve node may also need to have multiprocess functionality (mCurve)

Keep up the good work
-James

Hello James,

Yes you're right - a good idea. It would help in some situations to have the infos (xlength ... ) inside the output of idxSelect. I have to think about how to implement it.

Thanks and have a nice day
Karsten

---

p.s.: Curve has this feature already ...

---

Hello Karsten
thanks for the prompt response, but perhaps I did not explain
well
It is clear that using a formula can
to influence the formation of the surface ...
even if as in this case very " brainy " ;
but what I wanted to achieve is that simply by
the changes were driven by the position
of a point we call " Attractor ";
the variation of its cordinates, you'll have different distances
from the points of the grid ..
therefore taking advantage of the variation of this
parameter I want to vary the surface
That's why I think it is necessary that idx select
maintaining the incoming structure, and therefore also the output
of data relating to the points ....
I hope you can take action
Have a nice day

Hello Al,

sorry that I get you wrong. I added the meta infos in split and pointext. So please replace the files with the attached ones and try again.

Have a nice day
Karsten

Good Mornig Karsten.
truly unpayable as always
thank you....
I try, but I think now it's OK
good work
