"not sure how the NE reacts to multiple timers?"
There is no issue with multiple timers
"Is it neccesary?"
In most cases the same timer could be utilised for multiple loops.
There would need to be a triggering of second loop after first has met end condition.
Perhaps logic/compare a=0 (end condition for earlier loop) initiates new loopStart (trigger).
"global variables"
There does need to be a means of having unique variables for each loop.
Ideally, NE would recognise multiple loopStart/loopEnd pairs and attribute unique designators. Alternatively users could manually name each node pair, which would serve as the variable name. This approach though could be fraught with difficulties in terms of UX.
Would it be possible to have direct wire link between pairs, so loopStart get a randomly generated numerical designator on placement on the canvas, & then it is sent to LoopEnd via green wire?
Another alternative would be to introduce a txt string data type wire. It could also be used to externalise text inputting into “text” node. It may well have over uses.
Hello James,
wireing is my favorite to exchange the variable names by UIDs. I don't think that we need an additional text type for that. It would also need a lot of work in the base system. Furthermore I'm thinking about time stamps as an internal critera to trigger/reset loops.
How to store and manage the loop data isn't clear for me at the moment also.
One loop is simple, multiple loops not.
I was puzzling over the German "mit -KGV(n,m) * PI <= t <= KGV(n,m) * PI".
So, in English math the German KGV(n,m) is the Least Common Multiple of m and n.
LCM(n,m) is lcm(n,m) in Javascript. (n and m are integers in this example.)
German ggt(n,m) is the Greatest (Largest) Common Divisor, (Javascript gcd(n,m).
In Max's latest version of nodeeditor, unused node dot circles are NOT colored.
I prefer them all to be colored, pink gold and teal.
Does anyone else have this behavior?
I've re-installed different versions of nodeeditor several times...
In the file "colors.js", from the "core " directory, line 38 has a property, 'io_highlight': false //, replace its value with true, node nodes will become colored.
Made a helicoid node.
The v curves made with the stock Curve factory to not pass through the helical points.
The convertPts2 node uses MoI's Interpcurve factory so the curves pass through the points.
Max's Curve node has other versions of Interp., but the u and v points are not separated for inputs...
If network does not create the surface, or takes too long, a radial curve may be swept along the inner and outer helical curves.

Javascript cosh(x) and sinh(x) are not part of ecmascript5.
The binomial coefficients (N K) (vertical), for each order N saddle, are given in a row in pascal's triangle, using alternate entries.
For example, the Monkey saddle, with 3 dips, has coefficients 1 and 3.
The Octopus saddle, with 8 arm dips, has coefficients 1, 28, 70, 28, and 1.
Or the binomial coefficients can be easily calculated with factorials.
The formula for each order N, uses the Even values of K = 0, 2, ... (N for even N, N-1 for odd N).
The formula is the sum from K=0 to K=N of the binomial coefficient (N K) * x to the power(N-K) * y to the power(K),
* even powers of i, for a +/- factor.
Note that the .nod files use ConvertPts2 node, which can be downloaded elsewhere on the forum.
Network can be done on the curves, and the surfaces may be trimmed at a +/- z value.
The smelt petal is a trimmed Monkey saddle, with the Monkey saddle z-axis passing through the origin, and (1,1,1)
The z = f(u,v) in MathPoints may be easily done for 4, 6, and 7 arm_leg_tail dip surfaces.
Is there some way to add functions to MathPts node?
For example, perlinnoisefn.js, delaunator.js, and basicFunctions.js have functions used by other programs.
A very simple example would be say ellipticfn.js containing several functions, including
this.cosh = function(a,x)
{
var y = (a/2) * ( Math.exp(x/a) + Math.exp(-x/a));
return y;
}
Is there some way to get MathPts f(u,v) to be able to use cosh(a,u) with say elliptic.cosh(a,u)?
(Of course the catenary equation (a/2)* )exp(u/a) + exp(-u/a)) can be used in MathPts directly, but some other
desired functions are very much more complicated, with dozens of lines of code.)
