写了个PerlinNoiseEffect类，但效率很差，对于较大的bitmapData运行起来会比较累。

帖子原文：

One of my students (Alex Green) put together this example on mapping textures in 3DS Max using Photoshop. We are working on a site for Duke Energy and have been building washers and dryers all week.

The big joke around here is that we teach them to build jet planes (for fun) and next washers and dryers - that's reality!

Alex is a graphics design student and Flex Guru, and he is graduating in December!

Enjoy the video

for(var i:int = 0; i < 50; i ++)
            {
                var p:Plane = new Plane(new ColorMaterial(Math.random()*0xFFFFFF), Math.random()*180+10, Math.random()*180+10);
                p.x = Math.random() * 1000 - 500;
                p.y = Math.random() * 1000 - 500;
                p.z = Math.random() * 700 - 400;
                p.material.doubleSided = true;
                scene.addChild(p);
                p.useOwnContainer = true;
                planes.push(p);
                
                
                depthDemo = true;
                p.filters = [new BlurFilter()];
                
                p.alpha = Math.random() + 0.1;
            }

为每个矩形创建Blur效果

if(depthDemo)
            {
                for each(var do3d:DisplayObject3D in planes)
                {
                    if(do3d.container)
                        var deph:int = int(do3d.container.screenDepth);
                        do3d.filters[0].blurX = do3d.filters[0].blurY = int(deph * 0.005);
                }
            }

创建一个3D球体

var s:Sphere = new Sphere(new WireframeMaterial(), 150, 12, 8);
s.name = "sphere 11";
scene.addChild(s);

var bfx:BitmapEffectLayer = new BitmapEffectLayer(viewport, 500, 500);
viewport.containerSprite.addLayer(bfx);

bfx.addDisplayObject3D(s);
bfx.addEffect(new BitmapLayerEffect(new BlurFilter(2, 2, 8)));
bfx.setScroll(0, -4);
bfx.setTracking(s);
