对于越来越远的3D事物没有必要还保持太多的面
比如很远处的一个球，只需要12个面 甚至更少就可以了，不影响视觉效果

今日看到个DEMO

SVN ： http://code.google.com/p/bartekz/source/browse/

对于3D项目的效率肯定是大有帮助

do3d.calculateScreenCoords(camera);
trace(do3d.screen);
//渲染后执行才可以获取


2D的坐标定位到3D坐标 必须有个交点

var ray:Number3D = camera.unproject(viewport.containerSprite.mouseX, viewport.containerSprite.mouseY);
ray = Number3D.add(ray, camera.position);  
//这个抽象平面和DO3D保持一致    
var plane3d:Plane3D = new Plane3D(new Number3D(0, 1, 0), new Number3D());    
var jiaodian:Number3D = plane3d.getIntersectionLineNumbers(camera.position, ray);

camera.z = -200;
camera.focus * camera.zoom == Math.abs(camera.z)
漂亮

camera.focus * camera.zoom == 1000

真实

效率问题有待研究色彩也显得有些暗淡

顺便做了个加载的loading ，看看效果
