Rippling Flag | odd.ness.io

I created a basic Plane and applied a BitmapMaterial to it. Before each frame a sine wave is applied to the plane vertices.

var timeNumber:Number = 0;

override public function loop3D(e:Event):void
{
	if (!ready)
	{	return; }

	var p:Plane = rootNode.getChildByName("plane") as Plane;

	for(var segW:int = 0; segW <= p.segmentsW; segW++)
	{
		var newZ:Number = Math.sin(segW + timeNumber) * rippleHeight;
		for (var segH:int = 0; segH <= p.segmentsH; segH++)
		{
			var currentIndex:int = ((p.segmentsH + 1) * segW) + segH;
			p.geometry.vertices[currentIndex].z = newZ;
		}
		timeNumber += .05;
		if (timeNumber == 360)
		{
			timeNumber = 0;
		}
	}

	rootNode.rotationX = int(-(this.mouseY - (this.height/2))) * 0.5;
	rootNode.rotationY = int(-(this.mouseX - (this.width/2))) * 0.5;

	scene3D.renderCamera(camera3D);

}

var timeNumber:Number = 0;

override public function loop3D(e:Event):void

{

if (!ready)

{ return; }

var p:Plane = rootNode.getChildByName("plane") as Plane;

for(var segW:int = 0; segW <= p.segmentsW; segW++)

{

var newZ:Number = Math.sin(segW + timeNumber) * rippleHeight;

for (var segH:int = 0; segH <= p.segmentsH; segH++)

{

var currentIndex:int = ((p.segmentsH + 1) * segW) + segH;

p.geometry.vertices[currentIndex].z = newZ;

}

timeNumber += .05;

if (timeNumber == 360)

{

timeNumber = 0;

}

rootNode.rotationX = int(-(this.mouseY - (this.height/2))) * 0.5;

rootNode.rotationY = int(-(this.mouseX - (this.width/2))) * 0.5;

scene3D.renderCamera(camera3D);

}
