多个外部模型贴N张图的研究

我曾经也以为PV3D只能给COLLADA模型贴一张图，还为此去给人物模型重新UNWRAP UWV，浪费了我一个下午的时间。。。其实方法手册里都讲有了，我看了手册才后悔。。。以后就养成了先翻手册和代码的习惯。
例子：在3DS MAX中画了两个平面，每个平面各有一张贴图，材质分别命名为'map1'和'map2'，如图：
好了，代码来了~~
package
{
import flash.events.Event;
import org.papervision3d.events.FileLoadEvent;
import org.papervision3d.materials.BitmapFileMaterial;
import org.papervision3d.materials.utils.MaterialsList;
import org.papervision3d.objects.parsers.Collada;
import org.papervision3d.view.BasicView;
public class duoMapTest extends BasicView
{
private var matList:MaterialsList;
private var mat1:BitmapFileMaterial;
private var mat2:BitmapFileMaterial;
private var twoPlane:Collada;
private var loadedObjectNum:int;
public function duoMapTest()
{
super(550, 400, true);
init();
init3d();
startRendering();
}
private function init():void
{
loadedObjectNum = 0;
}
private function init3d():void
{
matList = new MaterialsList();
mat1 = new BitmapFileMaterial('map1.jpg');
mat2 = new BitmapFileMaterial('map2.jpg');
mat1.name = 'map1';
mat2.name = 'map2';
matList.addMaterial(mat1);
matList.addMaterial(mat2);
twoPlane = new Collada('twoPlane.DAE', matList);
twoPlane.scale = 0.1;
mat1.addEventListener(FileLoadEvent.LOAD_COMPLETE, onLoaded);
mat2.addEventListener(FileLoadEvent.LOAD_COMPLETE, onLoaded);
twoPlane.addEventListener(FileLoadEvent.LOAD_COMPLETE, onLoaded);
viewport.addEventListener(Event.ENTER_FRAME, enterFrameCheck);
}
private function onLoaded(e:FileLoadEvent):void
{
loadedObjectNum ++;
}
private function enterFrameCheck(e:Event):void
{
if (loadedObjectNum == 3)
{
viewport.removeEventListener(Event.ENTER_FRAME, enterFrameCheck);
scene.addChild(twoPlane);
}
}
override protected function onRenderTick(event:Event=null) : void
{
super.onRenderTick();
}
}
}
这个代码很简单，我懒，就不多讲了，关键就是材质的名称要跟你在3D软件里的一样，就行了，简单吧！
效果图：

lz麻烦您能不能给点小小的注释啊~~~对于初学者的我来说吃透它还是有点难度的---- |

noxss君.....是以豪爽的人吧...下次叫他注意加上注解。 |

DDM君 我发现用flex builder 开发3D游戏蛮爽的，代码有高亮，能自动弹出。 我本是做flex的，把你们代码贴上去稍加修改，发现可以完美运行！ |

其实，DAE类是可以直接提取dae文件中的贴图，并将他们贴到相应的地方上去的啊 daedocument 类的函数 public function parseLibraryImages():void { var list :XMLList = this.COLLADA.library_images..image; var element :XML; var hasImages :Boolean = false; this.images = new Object(); var loader :DaeImageLoaderThread = new DaeImageLoaderThread(this.baseUrl); loader.addEventListener(DaeParseEvent.IMAGES_COMPLETE, onImagesComplete); for each(element in list) { var image :DaeImage = new DaeImage(this, element); if(image.init_from && image.init_from.length) { this.images[ image.id ] = image; loader.addImage(image); hasImages = true; } } if(hasImages) loader.start(); else onImagesComplete(); } 是专门做这件事的啊 |

ps : 我是因为需要load lzma压缩的dae 所以将此函数从private改成public了 |
