[OS X] 3D Maps in Yosemite

WWDC 2014에서 발표된 Yosemite에 Map 앱에 3D가 추가되었습니다. 아직은 아이폰에서와 같이 Bird-eye 뷰를 제공하고 있지는 않습니다.

[iOS8] What is the ‘Metal’?


Metal provides extremely low-overhead access to the A7 GPU enabling incredibly high performance for your sophisticated graphics rendering and computational tasks. Metal eliminates many performance bottlenecks—such as costly state validation—that are found in traditional graphics APIs. Metal is explicitly designed to move all expensive state translation and compilation operations out of the critical path of your most performance sensitive rendering code. Metal provides precompiled shaders, state objects, and explicit command scheduling to ensure your application achieves the highest possible performance and efficiency for your GPU graphics and compute tasks. This design philosophy extends to the tools used to build your app. When your app is built, Xcode compiles Metal shaders in the project into a default library, eliminating most of the runtime cost of preparing those shaders.
Graphics, compute, and blit commands are designed to be used together seamlessly and efficiently. Metal is specifically designed to exploit modern architectural considerations, such as multiprocessing and shared memory, to make it easy to parallelize the creation of GPU commands.
With Metal, you have a streamlined API, a unified graphics and compute shading language, and Xcode-based tools, so you don’t need to learn multiple frameworks, languages and tools to take full advantage of the GPU in your game or app.
