I am perplex about the ScalePts Node!

Don't work as supposed! (like the previous nodes)

I believe that Points would move away but nothing more than the still start position! ???
(there is nothing drawn on the rest of the screen)

I must miss something!
2 points are selected at the start!

TextPts Node (English) surrely more possiblities but this is working! :)

---

Clone To Points ( English French) ...and better understand of what was the "Points" Node! (a simple variable 3D Array! :)

http://moiscript.weebly.com/points-e.html

Input Selection inside an Array Base(s) of Points

---

I must understand how works the ScalePts! ??? Its also used inside JitterPts...
That is for the moment mysterious! (for me) :)

---

Need some infos about the Modes Step Twist Explode of TransformPTS node :)

---

ConvertPts Node ( English French) You have the weekend for give me some infos about MathsPts, ScalePts :)
Because i am in the jungle with these 2 last!
Little images of very simple nodes example if possible! Thx by advance!

Before Infos about MathPts & ScalePts i can start that seems the more easy : the Basic Section! :)

Hi Pilou,
It does seem like ScalePts node is not working. Maybe it needs different inputs?
I suspect that the problem is that the Pink Dots represent a pointarray class, which is much more than just raw points.

Max wrote: "point/frame array", and also "One more node added - TextArray
It converts text data to pointarray. For each point can be set upto six values: x, y, z, x-rotation angle, y-rotation angle, z-rotation angle."

Karsten posted some explanations, related to his splitPts node and his PointExt node.
7777.675
9189.16
9189.20 "at first - yes it's a frame description:
x,y,z, Euler-angles (x,y,z by using rotation order x,y,z), scale mostly 1 (useful for some programming - can be used as scale factor or for transformation proposes (homogenous coordinates)."
7777.1336

Puzzled - Brian

The pSize (scale) input is Karsten's PointExt node does not seem to work either?

---

So wait and see more info! :)

Brian & Pilou,

>> It does seem like ScalePts node is not working. <<

ScalePt node works but only in combination with clonetoPts node.



>> For each point can be set upto six values. <<
Actually 7 values, including scale as shown on splitPts node output.

Have a great weekend

Perfect!
I wîll put your cool exemple!
Stay mathPts!

Great James!


Points node and MathPts node are similar.
PointArrays are output for each node.

MathPts permits the X, Y, and Z coordinates to be mathematically manipulated with parameters a, b, c and d, as denoted by pink f(u,v) output.
Write in your desired javascript mathematical formula. <<< add in examples with a,b,c,d,u,v>>>
X, Y, and Z appear in the Info window, and are the multiple point coordinates for each point of the output f(u,v) pointarray.

The MathPts node has A, B, C and D inputs available, by Right-Click on the node, click Input, and select next slot letter.
To remove the lowest existing slot, (assume it to be “b”), right click on b’s Dot, and select "Remove Slot".
A = a, B = b, C = c, and D = d. (the capitalization has no significance?).
MathPts seems to be "missing" the W range (~Z). (There must be some reason for "missing" W range?)
Sequentiually, u takes on the values of U range, v takes on the values of V range.

Points node has the W range available (~Z), as well as W num.

U num is the number of points between U range min (currently 0), and U range max (currently 10), inclusive, and becomes (part of) the X coordinate(s) of the point(s).
Similarly for V num (~Y) and for Points node, W num (~Z).

<<< examples>>>

Wiring the output f(u,v) to the input of the ConvertPts node yields 3 modes of output, Curves U, Curves V, or points.

- Brian


Local UV coordinates can be on a surface which could curve into 3d space.

The U, V, and W coordinates parallel the relative directions of X, Y, and Z coordinates. If you look at a 2D map image, U is the equivalent of X, and represents the horizontal direction of the map. V is the equivalent of Y, and represents the vertical direction of the map. W is the equivalent of Z and represents a direction perpendicular to the UV plane of the map.

A W coordinate for a 2D surface could be used to flip the orientation...

(The two nodes evolved from one or two of Max's scripts.)

Pilou Du bist der Wahnsinn.

Vielen Dank für Deine Mühen. :-)

@Apophis

Yes totally crazzy but absolutly necessary if like me you want have any chance to make something with it when you come from the moon! :)

---

Thx to James but some headaches for adapt its advice at any volumes! :)
(give a specific place to the new resized element : here its Bounding box ...
better than nothing but wanted a more specific one like a same x,y,z for same start / target Pt's element !

...and what is Mode Repeat, RepeatY, RepeatZ ?


ScalePts node (English French)

Pilou,

It is not clear to me what you mean, but cloneToPts node would generally be used with multiple points.
Attached is a better example of its use. ScalePts is multiprocessing values between 1 - 2 relative to distance from origin shown in red, to points in an array.

(Note: that my "PointArray" node is the same as your "Points" node; I changed the title in the code because I think it is a more appropriate description and less similar to "Point". It will still load OK in NE)

Hope that makes it clearer.

So MathPts can make a u,v network of a surface in 3d space by feeding its output into two ConvertPts, one with Curve U output, and one with Curve V output,
based upon a mathematical formula with Javascript math, which includes typical math such as sines, cosines, *, +, etc.
Feeding Curve U and Curve V into a network should make a surface.

James, your light color scheme look very good. Will you be making it available?
