Yelz的江湖

周日晚上，老妈打来电话讨伐我：“看了昨天的开幕么？你大姐开幕式录像还专门打了个越洋电话回来谈感受，就你沉得住气，不理老妈！”。

开幕式当然是看了，从头到尾，4个多小时，即便到后来，耳畔充斥着央视主持人千年不变，纯机械式的参赛国家介绍，我依然是精神抖擞，坚持到了主火炬点燃。总的感觉很好，尤其是开场时的29个巨人脚印和击缶倒计时，气势恢宏，非常震撼。短短的50分钟里，老谋子在全世界面前将中华的古老文明揉入一张光影画卷中，徐徐展开。琴棋书画，四大发明，丝绸之路，孔孟之道，盛唐气象，戏曲太极......，五千年的历史，孕育了太多太多的文化符号，而这一切，要在不足1个小时的表演时间里呈现给世人，本身就有些匪夷所思，所以即便中间稍有纰漏，也是无可指摘的。点火仪式的创意很不错，只是看着已过不惑之年的李宁在空中被吊足足3分钟，着实有些提心吊胆。

昨天又看了国奥比赛，实在有点鄙视自己了，典型的不见棺材不落泪。那两张红牌证实了一个流传在非洲人口中的传言: 中国人都会功夫。

小组赛被西班牙连捅4刀，一点脾气也没有的俄罗斯人居然在8强赛里3：1干掉了此前狂胜世界杯冠亚军的荷兰。单看结局，有些匪夷所思，但纵观整个场比赛，这个比分绝对是合情合理。

事实再一次证明：什么胜负统计；什么历史宿命；什么主力少打一场的体能优势， 统统都是扯淡。双方教练之间犹抱琵琶的机锋互探，足坛名宿的倚老卖老的指点江山，专业与非专业评论员故作高深的比赛前瞻，博彩公司老谋深算的让球开盘，这所有得一切，无非是这场好莱坞悬疑片的必要陪衬。不得不佩服希丁克这位天才的导演，似乎总有一种化腐朽为神奇的魔力，02年的韩国，06年的澳大利亚，今年的俄罗斯，无不是他的杰作。也许他会一直这么神奇，只要他老人家不会患上老年痴呆，有朝一日跑到中国来执教。

土耳其人的最后一秒钟的超级逆转和俄罗斯人面无冕之王的谋朝篡位，让我们这些中立国的球迷享受了一个难忘的足球周末。而我也以此为契机来更新一下久违的blog^_^，无论如何，不为这么一届跌宕起伏的欧洲杯留下只言片语，总是说不过去。

最早看的一届欧洲杯是92年在瑞典举行的那届，如日中天的巴斯滕在半决赛中罚失点球，成全了丹麦人得童话。要知道丹麦当时是顶替受制裁的南斯拉夫进入欧锦赛决赛圈的，留给他们的备战时间不过两周。 “我本来计划装修厨房，但却被召回国家队，到瑞典去参赛。”丹麦教练夺冠后极富喜剧性的说了这翻话。

96年欧洲杯也颇具喜剧性，伤病缠身的德国战车跌跌撞撞打到决赛，居然连个18人名单都凑不齐了，临时从国内抽调了一个叫比埃尔霍夫的大个儿，而这位仁兄最终成为历史上第一个金球的制造者，热血的捷克人成了他的牺牲品。那届比赛中，内德维德开始崭露头角，并在随后的几年中成为闻名足坛的铁血战士。我一开始倒没有太关注他，倒是我老姐关注他多些，因为少年时的内德酷似汤姆克鲁斯。那届比赛，我的伪球迷老爸也爬起来看了一场法国队的比赛，让我印象深刻。

2000年欧洲杯，正好上大三。荷兰对南斯拉夫比赛开始前，宿舍已经熄灯了，兄弟们把班里唯一的一台二手电视机抬到楼道里接上电源看比赛。正值夏季，电视机前左右两列一字排开，每人摆上一张凉席，一边和蚊子斗争，一边看球。荷兰最终6：1狂胜南斯拉夫，大家看得痛快淋漓，却压抑着不敢大声呼喊，只怕惊动了宿管科的人，现在想来，真是乐在其中。现在想来，当时还是挺疯狂的，第二天考试，夜里还坚持看完了葡萄牙对英格兰，目睹了葡萄牙人史诗般得逆转。

2004年欧洲杯，我已经在微软研究院上班了，终于不能像学生时代那么随心所欲，只能看自己喜欢的几个队的比赛。这届欧洲杯，总得说来经典比赛不太多，希腊最终夺冠，恐怕也没人能想到。12年一个轮回，12年前是童话，12年后是神话。

今晚是意大利vs西班牙，这两支球队，我都比较喜欢，希望他们能打出一场好看的比赛，即使是失败者，也要华丽的离开

农历四月八是佛诞，甘孜州每年在这个时候都会放假两天，全城老百姓都上跑马山游玩，又叫做转山会。

原本应该是个吉祥的日子，没想到却发生了这样大地震。

昨天下午，电话一直打不通，到了晚上7点才通过家里得固定电话联系上二姐，得知家人平安，也安心了些。和姐姐通了10分钟电话，还没讲完，余震又来了，姐姐赶紧挂了电话带爸妈出门躲避。

大家在户外呆了一整夜，今天早上才回家休息。下午又发生了多次余震，不知道什么时候才能结束，心里很堵。

成都还在下雨，老是呆在户外也不是办法。

默默祈祷，愿家乡人民能平安渡过难关。等交通一好，就把爸妈接来杭州。

The demands:

1. Implement skinned animation with vertex shader

2. Implement vertex diffuse, specular and fog in the vertex shader.

During the period I am focusing on implementing the above features, I refered different materials, D3DX SDK help, Google, Gamedev.net...such like that. They are helpful, but none of them is really work!

D3DX SDK sample doesn't show the way to do specular and fog. It also failed to emphasize the points new HLSL programmers (like me) need to pay attention. Pages searched by google are too cursory and full with mistake. It tooks me much time to get everything work. Here is the piece of shader code. I am trying to add enough comments so that you can not only know "how" but also know "why".

Becuase the matrix palette is usually too small for a whole model, we need to use ID3DXSkinInfo::ConvertToIndexedBlendedMesh to devide the whole model into sub-model to render seperatelly. I implemented the same function by myself, not very difficult. If you don't want to use .x format mesh, try to implement the function by yourself.

What's the matter with Tibet? – by i.elephant

 

After seeing Mr. Smith' Free Tibet MSN name, after talking to buddies in Austin and read some articles in US, I begun to realized how critical it is for the so called main stream media in US is making anti-China propaganda with the recent Tibet thing, and how successful they are in making our US friends (they are all nice and honest people) to believe what they saw on TV and other type of media…

 

As a "this generation Chinese" and as a honest person speak about the truth, I think I need to compose this message and have as many as people read it, to know what exactly the Tibet thing is.

 

First of all, I'd like to quote an article which is published on China Daily today by By Lisa Carducci, a Canadian writer, sharing her experience talking to Tibetans (Zang) people in China and in Nepal and how surprised she was. http://www.chinadaily.com.cn/cndy/2008-04/22/content_6633878.htm

 

The paragraph I am going to quote from her article is "Finally, I realized that the Tibetans outside Tibet are the victims not only of ignorance but of a well-organized campaign of misinformation. And it struck me that it may be the same for the Dalai Lama." Honestly, it is the first time for me to understand what non-Chinese Tibetans think and believe. As Lisa mentioned in the article, too bad, the information they believe to be true is from "a well-organized campaign of misinformation". Then who is the organizer of this never-ending campaign of misinformation? There is only one on the planet could be the "god father" of this - Dalai Lama.

 

Why? You may wonder. Is it because that he was "forced to flee the country"? Right, partially. To make the judgment, you have to understand why he was fled and why he wants to turn things over so badly even fifty years has gone.

 

Let me quote another line from Lisa's article "I told her that all the Tibetans I had met earlier knew very well what the central government of China had done for them and appreciated it." Yeah, appreciate, that's the word. Ask yourself, when is the last time you truly appreciate something from the bottom of your heart? That's the time your heart was truly touched and that's about something that really matters to you. Okay, back to the question, why Dalai Lama was forced to flee and why Tibetans in China appreciate what the central government has done?

 

It is a long long story, and story always could be told differently. In Dalai Lama's wording, when he was forced to leave, the so called traditional Tibet culture was destroyed. But he never mentions what exactly the so called traditional Tibet culture was. That's how liars speak about things. Let me give you the word – serfdom. If you don't know exactly what it means, google it. , And of course, Dalai Lama was the king and that explains why he wants the old time back so badly. There are some sites you can go for reference about the serfdom age and the development of Tibet in the new China age.

       http://www.chinaembassy.org.il/eng/zt/xzwt/t159564.htm

       http://english.people.com.cn/features/tibetpaper/tibet.html

       http://www.tibet.cn/english/zt/whitebook/index.html

       http://www.dalai-liar.com/

 

Now you understand what's the real matter of Tibet, the history and the motive. Surprisingly, Dalai Lama has worked so desperately in making his propaganda, and this time he even made some of the main stream media buy in his value, and so come the news you saw on TV about the so called March Tibet riot in China.

 

Yes, there was a riot, bad people were organized to destroy the shops on street, etc., the standard riot things in a violent protest (and more than that this time, definitely), to make everything looks true to Dalai Lama's story. The police did their best to protect the residents. However, there were still victims. Please refer to the photos here: http://www.anti-cnn.com/forum/en/thread-649-1-1.html. It is touching, especially the photo at the bottom which is the five shop girls were torched ALIVE by rioters, oldest 24 (Yang Dongmei, right ), yongest 19 (Chen Jia, left). Totally there wer 13 residents were killed by the rioters. For more stories about "the five young women who burned to death", see here: http://www.iht.com/articles/2008/03/28/asia/tibet.php

 

But what the media in US reported? They refuse to acknowledge the victims of Lhasa riot, they five shop girls lost their lives to the rioters either hired by or motivated by the propaganda from Dalai Lama. Instead, they fabricated the stories that the Chinese police pressing peaceful protesters. Yes, fabricated! Surprise, ahha? Yeah, me too, but that's the truth. Actually, you will laugh about how stupid it is. Basically, what CNN did is just copied and pasted its own video tape of the Tibet Protest movement in India and has fabricated it as in Gansu Province/ Lhasa, China "peaceful" protest movement with Chinese cops in khaki British colonial style uniforms. That's really funny a low IQ. For details, check it out here: http://www.globalresearch.ca/index.php?context=va&aid=8697. And if you do a research, you will find other medias, including Washington Post, did same IQ level stupid "imaginary story telling" reporting.

 

The photo of the five victim girls is still vivid in my mind…for those reporters, don't you feel any level of SHAME??? I have no right wording to express my feeling now. The feeling is very complex. I like the democracy in US and the people there. 99.99%+ of the people there are nice an honest, but this time, the 0.01%- bad people manipulated good people's feeling and trust, and made them believe in the pressing of peaceful protest in Tibet story and made them believe the so called Free Tibet is meaningful thing. I felt so bad when I saw my best friend in US mentally joined the so called Free Tibet thing. That motivates me to write this message, to let more nice and honest US people know that it is the so called Free Tibet people torched five shop girls alive in Tibet, and the god father who won Nobel prize of peace was the biggest slave owner in the serfdom age…

 

Last and least question, why US media do so? I think you already have your idea. No matter it is "All western journalists need to sell news and stories. Their livelihood depends on the stories. Sometimes they have to exaggerate" (2008 Olympics, China, Tibet, by ciga), or they are also nice and honest people just stupidly believed what they thought to be true from Dalai Lama, or there is higher priority agenda such as national interest…who knows, who cares. What happened is what happened, let's face it, in an honest manner.

 

Looking forward, be honest like a real man, don't fabricate, don't ruin beautiful things, especially the Olympic, the thing supposed to be the purest, don't ever think about ruining it. Come one, don't tell me you haven't got the idea that the whole Tibet thing is part of the plot of ruining the Beijing Olympic. Anyway, you are adult, you have your judgment. Like them, they have their judgement:

There is an old saying that for all the bad things you did, you will be punished, sooner or later. Let's just wait and see…

灵峰、孤山和西溪自古以来就是杭州赏梅的三大胜地。说起来，最为所人知的便是孤山，那个“梅妻鹤子”的林逋和那句“疏影横斜水清浅，暗香浮动月黄昏”虽时隔千年，尤让人心向往之。中国文人向来对梅花青睐有加，说到底是孤芳自赏的心里在作怪，“零落成泥碾做尘，只有香如故”，大概就是文人仕途失意，处江湖之远后的自我安慰。所以文士们赏梅，讲究的是意境：或是在清冷的冬晨，朔风凛冽，天地肃杀；或是在幽冷的晴夜，月色朦朦，文士们踩着厚厚的积雪在小道上踽踽独行，忽一抬头，正看见一朵怒放的梅花在枝头怒放，那便是有意境了。我们老百姓看梅花就没那么多讲究，踏雪寻梅固然别有乐趣，但与其顶风冒雪，还不如等到明媚的春日，去梅园看一看满树盛开的各色梅花：在花丛中拍几张照片，拈过花来嗅一嗅阵阵幽香，即便是和他人摩肩接踵，也是件开心的事。上周末就是这样的天气，所以一大早便去了植物园，一路径直来到灵峰，在梅花的海洋里徜徉了一番。

公司的3D大型网游天下贰再次内测了，从老天下贰回炉到今天重新内测，只有10个月时间，游戏内容，美术风格，收费模式，全都改了，且不说改得是否成功，效率的确够高。老天下贰我玩得不多，只到10多级，印象最深的就是从新手村出来，一不小心掉到山下小河里，游了半天才找到上岸的地方，灰头土脸跑回去，结果没过多久，再次掉到河里......。新天下贰里选了魍魉，也玩到10多级了，渐入佳境。就画面来说，比以前精致了不少，个人还是很喜欢；任务系统做得也不错，新手的上手难度明显降低。从程序上来说，bigworld引擎经过一年多的优化，无论是效率还是表现力，应该都有提高。之前在悉尼的时候到bigworld总部去访问过，其间谈到了地表渲染部分的优化，差不多就是progressive mesh的概念，看起来也很好的运用到新的游戏场景中了。
