Flex+Papervision3D三维技术研究（基础篇一）

在上一篇上讲到了开发工具及包需要的包，下面让我们动手来实现一下第一个3D场景。

1、在eclipse中新建一个flex项目，添加Papervision3D.swc包到flex_libs中，设置好目录结构。上图

package com.neil
{
import flash.events.Event;

import mx.core.UIComponent;

import org.papervision3d.cameras.Camera3D;
import org.papervision3d.events.InteractiveScene3DEvent;
import org.papervision3d.materials.ColorMaterial;
import org.papervision3d.objects.primitives.Plane;
import org.papervision3d.render.BasicRenderEngine;
import org.papervision3d.scenes.Scene3D;
import org.papervision3d.view.Viewport3D;


public class MainView extends UIComponent
{
private var viewport:Viewport3D;//添加一个3D窗口，所有3D对象将透过这个窗口观察
private var scene:Scene3D;//添加一个3D场景，跟flash中的舞台含义相似
private var camera:Camera3D;
private var renderer:BasicRenderEngine;
private var material:ColorMaterial;
private var plane:Plane;

public function MainView()
{
init();
}
private function init():void{
viewport=new Viewport3D(640,480,false,true);
addChild(viewport);
scene=new Scene3D();
camera=new Camera3D();
renderer=new BasicRenderEngine();

material=new ColorMaterial(0xcc00FF);
material.interactive=true;
material.doubleSided=true;


plane=new Plane(material);
scene.addChild(plane);

addEventListener(Event.ENTER_FRAME,onEnterFrame);
}
private function onEnterFrame(e:Event):void{
plane.yaw(2);//设置动画速度
renderer.renderScene(scene,camera,viewport);
}
}
}
