Metal Programming Guide Metal 编程指南 About Metal and this Guide 关于Metal和本⽂ The Metal framework supports GPU-accelerated advanced 3D graphics rendering and data-parallel computation workloads. Metal provides a modern and streamlined API for fine-grain, low-level control of the organization, processing, and submission of graphics and computation commands and the management of the associated data and resources for these commands. A primary goal of Metal is to minimize the CPU overhead necessary for executing these GPU workloads. Metal框架⽀持GPU加速的3D图形渲染和并⾏数据计算。Metal提供了⼀系列的API⽤于在细粒度和低层次上组 织、处理、提交图形绘制指令、并⾏计算指令，并管理和这些指令相关联的数据和资源。Metal的⼀个主要⽬标 是减少GPU执⾏这些计算的必要的开销。 At a Glance 概述 This document describes the fundamental concepts of Metal: the command submission model, the memory management model, and the use of independently compiled code (i.e., graphics shader functions or data-parallel computation functions). The document then details how to use the Metal API to write an app that: sets hardware state necessary for graphics or data-parallel compute workloads, commits commands for execution by the GPU, manages memory allocations, including buffer and texture objects, and manages compiled (or compilable) graphics shader or compute function code written in the Metal shading language. 本⽂描述Metal的基本概念：计算指令分发模型，内存管理模型，独⽴编译的代码的使⽤（⽐如图形着⾊器程序 或者并⾏数据计算程序）。接下来本⽂详述如何使⽤Metal的API实现app ： 为图形渲染或是并⾏计算设置必要的硬件状态 提交命令到GPU执⾏ 管理内存分配，包括buffer对象和textrue对象 管理编译好的（可编译的）图形着⾊程序或是⽤Metal着⾊程序语⾔写的并⾏计算程序 How to Use This Document 如何使⽤本⽂ This document contains the following articles: Fundamental Metal Concepts (page 9) briefly describes the main features of Metal.
 Command Organization and Execution Model (page 10) explains creating, committing, and executing commands on the GPU. Resource Objects: Buffers and Textures (page 18) discusses the management of device memory, including buffer and texture objects that represent GPU memory allocations. Functions and Libraries (page 26) descr
