剖透视光影表达


  1. 讲述错误的剖面表达

  2. 大神表达

    • 佐罗刀使用前炸开分组，过多分组会导致崩溃
    • 填充剖面--切割剖面--处理正确光影
    • 空气墙建立
      • 拉伸填充面--封住面--附中性灰颜色避免倾向
      • vray--改变空气墙为二次反射可见（即隐藏掉空气墙）
    • 参数设置
      • color mapping (调整之后颜色会很奇怪，记得VFS调整看)
        • Type-Exponential
        • M&B-1.0
        • Don't affect colors
      • GI (凸显楼梯，梁板转角处细节)
        • AO-0.8 64 80 (此时渲染尺度是天津大学建筑学楼)
      • Output调整到自己希望的尺寸
      • 间接照明全部改为Brute force (光影计算比发光贴图更准确，但是相应时间会增加很多)
        • 务必修改蒙特卡洛算法参数，否则效果很差
        • 长时间渲染建议云炫，很实惠而且省机器，8倍速度
    • PS后期
      • 32位曝光选择--进入camera raw
      • camera raw 
        • 拉回高光，阴影细节（抠住你关注图面的细节）
        • 处理蒙特卡洛渲染出现的噪点
          • 按住alt拉高camera raw中蒙版选项--目的是使面更加锐利
          • 拉高明亮度，并增加明亮度细节--目的是去除大面噪点

Interview with Steve Jobs, WGBH, 1990

Interviewer: what is it about this machine? Why is this machine so interesting? Why has it been so influential? Jobs: Ah ahm, I'll give you my point of view on it. I remember reading a magazine article a long time ago ah when I was ah twelve years ago maybe, in I think it was Scientific American . I'm not sure. And the article ahm proposed to measure the efficiency of locomotion for ah lots of species on planet earth to see which species was the most efficient at getting from point A to point B. Ah and they measured the kilocalories that each one expended. So ah they ranked them all and I remember that ahm...ah the Condor, Condor was the most efficient at [CLEARS THROAT] getting from point A to point B. And humankind, the crown of creation came in with a rather unimpressive showing about a third of the way down...

Apple's One-Dollar-a-Year Man, By Steve Jobs, 2000

(FORTUNE Magazine) – Now that Steve Jobs has showed his hand on Apple's Internet and system software strategies and dropped the "interim" from his title, other questions loom. He's always denied it, but isn't it true that his old company, Next, did wind up taking over Apple? Will there ever be an encore to the 15-year-old Macintosh? Short of that, does Apple have any plans to jump into the "Internet appliance" fray? Will Apple ever build computers for business people again? And what, pray tell, does Steve think of all these young Internet zillionaires? Let's ask. Practically every technology that your old company, Next, possessed when Apple acquired it in 1997 is now being used by Apple in some strategic way. This must seem like sweet vindication.  The thing about Next was that we produced something that was truly brilliant for an audience that our heart really wasn't into selling to--namely, the enterprise. I suppose if you were wr...

Steve Jobs: `There's Sanity Returning', 1998

Nobody can doubt the charisma of Steven P. Jobs. The interim CEO of Apple Computer Inc., who returned to the company last July after his ignominious 1985 ouster, has brought back his legendary vision, impatience, and infectious passion for the Macintosh. Jobs spoke to Business Week Correspondent Andy Reinhardt in Apple's stark, fourth-floor boardroom, just after the company rolled out its new software strategy on May 11. Note: This is an extended, online-only version of the Q&A that appears in the May 25, 1998, issue of Business Week. Q: Now that you've introduced the new, bold-looking iMac, are you going to do some radically different products? A: There's a lot of talk about such things -- about handhelds, set-top boxes. A lot of computer companies have been searching for a consumer product. My view is that the personal computer has been the most successful consumer product of the last 10 years. What we have to do, what the industry stopp...
