Papervision3D旋转和矩阵
问题描述：今天用FLARManager做AR，发现PV3D里修改矩阵后rotation不更新。
问题解决：在网上找到Kevin Cao的解决办法：调用yaw(0)一下，使其更新解决。

Papervision3D坐标转换
3D转2D
do3d.calculateScreenCoords(camera3D);
var real2DX:Number = do3d.screen.x + viewport3D.width/2;
var real2DY:Number = do3d.screen.y + viewport3D.height/2;
2D转3D
var ray:Number3D = camera.unproject(viewport.containerSprite.mouseX, viewport.containerSprite.mouseY);
ray = Number3D.add(ray, camera.position);

4个援交女，不一样的性格，不一样的目的。
援交女最终目的可以是金钱、虚荣、刺激、爱情。
影片尺度比较大，正宗香港三级片。

“科学的终极目的在于提供一个简单的理论去描述整个宇宙。”
人择原理：“我们看到的宇宙之所以这个样子，乃是因为我们的存在。”
弱人择原理：“在一个大的或具有无限空间和/或时间的宇宙里，只有在空间-时间有限的一定区域里，才存在智慧生命发展的必要条件。”
强人择原理：“存在许多不同的宇宙或者一个单独宇宙的许多不同的区域，每一个都有自己初始的结构，或许还有自己的一套科学定律。”

我想象了一个故事，这个故事改变了我。
“Why is a raven like a writing desk?”
-----
“Because it can produce a few notes, though they are very flat.”
“it is nevar put with the wrong end in front.”

Auther's Note
Enquiries have been so often addressed to me, as to whether any answer to the Hatter's Riddle can be imagined, that I may as well put on record here what seems to me to be a fairly appropriate answer, viz. 'Because it can produce a few notes, though they are very flat; and it is nevar put with the wrong end in front!' This, however, is merely an afterthought: the Riddle, as originally invented, had no answer at all.
