We've got three components, our 2D which is Quartz, our 3D which is OpenGL, and our media layer which is QuickTime.
我们有三个组成部分，2D是Quartz，3D是OpenGL，媒体层是QuickTime!Q+hh_quOBiK!v.r0。
And they're all seamlessly integrated right into the operating system.
它们都无缝集成到了操作系统当中9efEd,s*MdY。
So let's take a look at Quartz.
