[Papervision3D] Easing Transform Matrix3D

[UKLA]

Yeah, I am using that when the user clicks on a plane within the carousel
do3d in order to transform the carousel so that the clicked plane is facing
the camera.

Click on a plane and it sets these variables:
var radians:Number = (carousel.rotationY - e.displayObject3D.rotationY) *
Quaternion.DEGTORAD;
slerp = 0;
currentQuat = Quaternion.createFromMatrix(carousel.transform);
targetQuat = Quaternion.createFromAxisAngle(0, 1, 0, radians);


function renderData(e:Event):void {
	
	for (var i:uint=0;i<planesArray.length;i++){
		
		lines3d.removeLine(linesArray[i]);
		var line:Line3D = new Line3D(lines3d,lineMaterial,1,new
Vertex3D(planesArray[i].x, planesArray[i].y, planesArray[i].z),new
Vertex3D(planesArray[i].x/4, -200, planesArray[i].z/4))
		lines3d.addLine(line);
		linesArray[i] = line;
	}
	
	
	slerp += (1 - slerp) * .1;
	var quat:Quaternion = Quaternion.slerp(currentQuat, targetQuat, slerp);
 
	carousel.transform = quat.matrix;
	renderer.renderScene(scene, cam, viewport);
}



Not sure how to use this for the mouse dragging in my original post.

Thanks,
Craig
