passing variable to gaia page

using deeplink

Gaia.api.goto(Pages.YOUR_PAGE + "/variable);

function transitionIn():void
{
var type:String = Gaia.api.getDeeplink().substr(Gaia.api.getDeeplink().lastIndexOf("/") + 1);
handleDeeplink(type);
}
function handleDeeplink(__arg:String):void

away3d how to move 3D object along a path - part2

preFab 還提供兩種工具 Path Extruder and Path Animator
Path Extruder 可以在 Path 上貼上材質(ie：草皮/柏油/水泥...etc.)
可以用 Geometry -> Path -> Path Extruder
首先點出你要的物件

setting：
select path
subdivision -> 4
closepath
allgntopath
coversegment
mapfit
選材質
build

Path Animator 可以用來預覽效果
Geometry -> Path Animator

seletc path
use camera
offset y:100
allgn to path
preview(camera 沿著 path 移動)

use Object3d
object(your car)
offset y:100
allgn to path
preview(3d object 沿著 path 移動)

away3d how to move 3D object along a path - part1

away3d how to move 3D object along a path
away3d 裡有支援 path animator，可以沿著路徑移動 3D 物件，
以往必需先自己建立路徑，再丟給 PathAnimator 處理

pseudocode：
var aPath:Array = [
new Vector3D(-1000, -1000, -2000),
new Vector3D(-1000, 0, 0),
new Vector3D(1000, 0, 0),
new Vector3D(1000, 1000, -2000),
];
var p:Path = new Path(aPath);
pa = new PathAnimator(path, arrow, o);

簡單的路徑可以自己建立，但是複雜的路徑
這樣搞大概永遠都下不了班，
為了讓大家能夠準時下班，這裡介紹一個好用的工具

away3d load obj/md2/3ds/mqo model

away3d load obj/md2/3ds/mqo model
away3d 可以載入多種 3D 格式,
有興趣可以去翻翻 away3d.loaders。

load obj
loader = Obj.load("resource/Static.obj")

load 3ds
loader = Max3DS.load("resource/monster.3DS", { scaling:5.0 });

load mqo
loader = Metasequoia.load("resource/mion/mion.mqo");

load md2(following md2 texture path)
loader = Md2.load("resource/ogre.md2", { scaling:0.05 } );

objcontainer = new ObjectContainer3D(loader);
scene.addChild(objcontainer);

away3d cube/skybox material

away3d cube/skybox material

cube 六個面貼上相同的材質
cube = new Cube( { material:"blue#white", x: -100, width:50, height:50, depth:50 } );
或者是
cube = new Cube();
cube.material = material;
cube.width = 200;
cube.height = 200;
cube.depth = 200;

cube 六個面貼上不同的材質
cube = new Cube();
cubeMaterial = new CubeMaterialsData();
cubeMaterial.front = new ColorMaterial("random");
cubeMaterial.back = material2;
cubeMaterial.bottom = new ColorMaterial("random");
cubeMaterial.top = new ColorMaterial("random");
cubeMaterial.left = material1;
cubeMaterial.right = new ColorMaterial("random");
cube.cubeMaterials = cubeMaterial;

away3d camera note

away3d camera note
camera 相關原理可以先參考這兩篇
http://www.flashmagazine.com/Tutorials/detail/away3d_basics_the_cameras/
http://blog.tartiflop.com/2008/08/understanding-zoom-focus-and-field-of-view-in-papervision3d/
away3d 有四種 camera，分別是
camera3D：default camera
TargetCamera3D：automatically look at a specified target object
SpringCam：1st and 3rd person camera
HoverCamera3D：hover round a specified target object

本文介紹(最常用) HoverCamera3D，
利用改變 camera.panAngle 及 camera.tileAngle
來產生旋轉及放大縮小的 3D 效果。
