Becuse transparent, we can see it’s back outlines.If we use Cube create it like this:

var v :View3D = new View3D({x:200, y:200, color:0xffff0000});
var cube :Cube = new Cube();//sban
var cm: WireframeMaterial = new WireframeMaterial(0xffff0000);
cm.wireAlpha=0.5;
cube.material = cm;
cube.rotationX=15;
cube.rotationY=15;
cube.rotationZ=15;
v.scene.addChild(cube);
addChild(v);
v.render();

it’s NOT what we want

This code can show the back outlines:

cube.bothsides=true;

But we can not remove the catercorner where each face. If we increase segment like this:

cube.segmentsW=2;
cube.segmentsH=2;

My God!It dose not help much. Away3d use triangle to draw the segment in cube, in other words, every segment contains two triangles in cube. May be not we achieved with cube.So I sue WireCube as follows:

var v :View3D = new View3D({x:200, y:200, color:0xffff0000});
var cube : WireCube = new WireCube();//sban
var cm: WireframeMaterial = new WireframeMaterial(0xffff0000);
cm.wireAlpha=0.5;
cube.material = cm;
cube.rotationX=15;
cube.rotationY=15;
cube.rotationZ=15;
v.scene.addChild(cube);
addChild(v);
v.render();

Wire 3d object can not be set segment number.

BS:Outline property of the 3d object can highlight the bounds.

Awayd is a great realtime 3d engine for flash application.This post demonstrates how to get started with away3d 3.5.Now, let us use away3d create a cube…

1,download the 3.5 version and import into your project
2,write the following code into your entry file:

var v:View3D = new View3D({x:200, y:200, color:0xffff0000});
var cube:Cube = new Cube({width:150, height:150, depth:150});
v.scene.addChild(cube);
addChild(v);
v.render();

compile and run it, you will see:

It’s a cube, but it looks like a square.Insert the following code:

cube.rotationX=15;
cube.rotationY=15;
cube.rotationZ=15;

got this:

The three-demensional coordinate is as follows

If face the direction of the x, yaxis, the rotation is inverse hour, but the z is clockwize.Why not same?

View3D is a container used for storing camera, scene, session, renderer and clip references, and resolving mouse events. Every time after changing the properties of the 3d object, must explicitly call the view3d’s render method.

We cant paste a material to the cube faces like this

cube.material = new BitmapMaterial( (new myTexture as Bitmap).bitmapData );
...
[Embed (source="meta2.jpg")]
private var myTexture:Class;

or use BitmapFileMaterial:

cube.material = new BitmapFileMaterial("meta2.jpg");

Now, how to make the material looks a lit lax? clip the image or the bitmap.

var b :Bitmap = new myTexture as Bitmap;
var bd :BitmapData = new BitmapData(50,50);
bd.draw(b, null, null,null,new Rectangle(0,0,50,50));
cube.material = new BitmapMaterial( bd );

可以实现人物全身换装，并可以加肢体动作，衣服可以多样化，并可以360展示。运行效果图之一：
