The next layer on top of Darwin is killer graphics.
達爾文的上面一層是殺手級的圖像。
We've got three components, our 2D which is Quartz, our 3D which is OpenGL, and our media layer which is QuickTime.
我們有三個組成部分，2D是Quartz，3D是OpenGL，媒體層是QuickTime。
And they're all seamlessly integrated right into the operating system.
它們都無縫集成到了操作系統當中。
So let's take a look at Quartz.
那么我們來看一下Quartz。
Quartz is PDF-based. What does that mean?
Quartz是基于PDF的。什么意思呢？
You know when you go to the web and you see PDF documents,
當你在網上看到PDF文檔時，
you read them with Acrobat, this great technology invented by Adobe.
你可以用Acrobat來閱讀，這是Adobe公司發明的一項偉大的技術。
Well, that technology is now at the core of Mac OS X's graphics. So you can image PDFs instantly.
這項技術現在是Mac OS X繪圖的核心。這樣你就可以立即對PDF文件進行成像。
We have On-the-fly PDF rendering, anti-aliasing and compositing,
我們現在擁有即時的PDF渲染、抗鋸齒和合成技術，
which will blow you away, built at the core of the OS.
這些都會讓你大吃一驚，并且搭建在操作系統的核心層。
So now all applications get this for free.
現在所有的應用程序都可以免費使用。
And we have built in transparency into the model and I'll show you that in a few minutes.
我們已經在模型中加入了透明度，我會在幾分鐘后展示給你們看。
Our OpenGL 3D standard is the most widely supported 3D standard in the industry.
我們的OpenGL 3D標準是業界廣泛支持的3D標準。
It's very advanced and we have full hardware support for it, built in again to the core of the operating system.
它非常先進，我們有完整的硬件支持，同樣內置在操作系統的核心層。
And obviously QuickTime for digital video and audio, live internet streaming, internet standard,
當然還有支持數字視頻、音頻、實時互聯網流媒體、因特網標準的QuickTime，
33 percent market share, built into the core of the OS.
33%的市場份額，內置于操作系統的核心層。
So those are our killer graphics.
上述這些就是我們的殺手級的圖像。
