the below is pre-posted on the big list. the only answer came from brad garton, and while i'm grateful for his attention, i'd rather implement this in a language that i can actually understand.

is there an elegant javascript solution for this? i'd be grateful for a push in the right direction. my procedural programming skills have drastically withered on the vine.

i've got a series of two-item lists that look like this:

i would like to build in interpolation for those lists. so as the new 

lists come in, interpolated versions of them are added. it's ok if 

the lists come fast and furious. the above would be changed to

take note of the slower interpolation of the second list item during

this is a quick hack, so i doubt the example below is elegant.

could probably be streamlined, but maybe it gets you in the right 

    var incrA, incrB, x, y, dist = 0;

    b = arguments[1];        

    dist = Math.max(Math.abs(x),Math.abs(y));        

        incrA = x / dist;        

        incrB = y / dist;    

        outlet(0, Math.floor(a0+0.5), Math.floor(b0+0.5));

volker.

/* --- start listInterpol.js ---- */
var a = 0;
var b = 0;
var a0 = 0;
var b0 = 0;

function list() {
	var incrA, incrB, x, y, dist = 0;
	a0 = a;	b0 = b;	
	a = arguments[0];	
	b = arguments[1];		
	// calc difference	
	x = a - a0;	
	y = b - b0;	
	// max. distance	
	dist = Math.max(Math.abs(x),Math.abs(y));		
	if(dist != 0) {
		incrA = x / dist;		
		incrB = y / dist;	
	}
	for(i=0; i
		a0 += incrA;
		b0 += incrB;
		outlet(0, Math.floor(a0+0.5), Math.floor(b0+0.5));
	}
}
