so heres the next step in my ribon madness

multi ribbons and some nearly satisfactory motion. i was aiming for smooth elipses but got something not un pleasing, I did mention i need to learn a lot more math.

this is built off my previous ppv sound example.

i added a tween to a circle, woo hoo. its still fun :)

oh i need to learn more math.

midippvthingy31

and the code i added to tween

function circle(){
var angleOffset:Number = Math.PI*2/255;
var radius:Number = 300;
var angle:Number = 360;
var planeX:Number;
var planeZ:Number;

		for(var i:int =0;i<255;i++)
	{
		planeX = Math.cos(angle)*radius;
		planeZ = Math.sin(angle)*radius;
		TweenLite.to(pointArray[i], 5, {x:planeX, z:planeZ});
		angle += angleOffset;
	}

}

enjoy

Some flash math art based on stuff i found, i’ll put links up soon to the original source.

 heres the example. if it does nothing after a few seconds reload it. part of the beauty of random math art is it may be doing something absolutely beautifull on such a small scale only it knows its happening

And the code.

[SWF(width=400, height=400)]
var numA:Number = new Number(Math.random()* 2000);
var numB:Number = new Number(Math.random()* 2000);
var numC:Number = new Number(Math.random()* 1000);
var shape:Shape = new Shape();
var bmpd:BitmapData = new BitmapData(400, 400, false, 0xffffff);
var bmp:Bitmap = addChild(new Bitmap(bmpd)) as Bitmap;
var r:Number = numC;
bmp.width = bmp.height = 400;

var points:Array = new Array();
var minDist:Number = 400;
var a0:Number = 0;
var a1:Number = 0;
var v0:Number = Math.random() * .2;
var v1:Number = Math.random() * .2;

addEventListener(Event.ENTER_FRAME, tick);

function tick(event:Event):void
{
	var p:Point = new Point(r + Math.cos(a0) * r, r + Math.sin(a1) * r);
	points.push(p);
	draw();
	a0 += v0;
	a1 += v1;
}

function draw():void
{
	var p0:Point = points[points.length - 1] as Point;
	for(var i:int = 0; i < points.length - 1; i++)
	{
		var p1:Point = points[i] as Point;
		var dx:Number = p0.x - p1.x;
		var dy:Number = p0.y - p1.y;
		var dist:Number = Math.sqrt(dx * dx + dy * dy);
		if(dist < minDist)
		{
			shape.graphics.clear();
			shape.graphics.lineStyle(0, 0, (1 - dist / minDist) * .8);
			shape.graphics.moveTo(p0.x, p0.y);
			shape.graphics.lineTo(p1.x, p1.y);
			bmpd.draw(shape);
		}
	}
}

 here it is, where i got this from.
