Away 3D实现360度全景图的二种全景图.

 

01:触发3D代码运行的Cover.as类

 

package { import flash.display.Bitmap; import flash.display.BitmapData; import flash.display.Sprite; import flash.events.Event; import flash.events.MouseEvent; import flash.filters.BlurFilter; import flash.text.TextField; import flash.text.TextFormat; public class Cover extends Sprite { private var parentMovie:Sprite; private var coverSquare:Sprite; private var coverText:TextField; private var text:String; private var blurredParent:Bitmap; private var stageW:Number; private var stageH:Number; public function Cover(parent:Sprite,w:Number = 465, h:Number = 400, txt:String = null) { parentMovie = parent; stageW = w; stageH = h; text = txt; super(); // Build the "disabled" state coverSquare = new Sprite(); coverSquare.graphics.beginFill(0x000000,0.05); coverSquare.graphics.drawRect(0,0,parentMovie.stage.stageWidth,parentMovie.stage.stageHeight); coverSquare.graphics.endFill(); addChild(coverSquare); // Create explanatory text var format1:TextFormat = new TextFormat(); format1.color = 0x000000; format1.size = 12; format1.align = "center"; format1.font = "_sans"; coverText = new TextField(); if(!text){ coverText.text = "Roll over to view"; } else { coverText.text = text; } coverText.setTextFormat(format1); coverText.width = parentMovie.stage.stageWidth; // Prep for blurred parent blurredParent = new Bitmap(); this.addChild(blurredParent); parentMovie.stage.addEventListener(Event.MOUSE_LEAVE,showCover); parentMovie.stage.addEventListener(MouseEvent.MOUSE_OVER,hideCover); this.addEventListener(Event.ENTER_FRAME,initCover); showCover(); } private function hideCover(e:MouseEvent):void { trace("hideCover "+e.stageX); if(e.stageX < stageW && e.stageX > 0 && e.stageY < stageH && e.stageY > 0){ this.visible = false; } } private function showCover(e:Event = null):void { if(!this.visible){ refresh(); } // Turn on cover this.visible = true; } private function initCover(e:Event):void { this.removeEventListener(Event.ENTER_FRAME,initCover); refresh(); // Turn on cover this.visible = true; } public function refresh():void { var bits:BitmapData = new BitmapData(stageW,stageH); bits.draw(coverSquare); bits.draw(parentMovie); var backgroundImage:Bitmap = new Bitmap(bits); backgroundImage.filters = new Array( new BlurFilter(6,6,4) ); // Copy the blurred text and add the text var textOverlay:BitmapData = new BitmapData(stageW,stageW,false); textOverlay.draw(backgroundImage); textOverlay.draw(coverText,null,null,null,null,true); blurredParent.bitmapData = textOverlay; } } }
