问题描述

如何以编程方式获得金属的最大纹理大小(宽度和高度)?使用openGL我可以做到:glGetIntegerv(GL_MAX_TEXTURE_SIZE, ...)但是如何用Metal做到这一点?

How to get programmatically the maximum texture size (width and height) with metal? with openGL i can do: glGetIntegerv(GL_MAX_TEXTURE_SIZE, ...) but how to do it with Metal ?

推荐答案

当前没有用于检索Metal设备最大纹理尺寸的API.您应该参考金属功能集表，并而是将其添加到您的应用中.

There is currently no API for retrieving the maximum texture dimensions of a Metal device. You should consult the Metal Feature Set Tables for this information and include it in your app instead.

对于运行当前版本的iOS/tvOS/iPadOS的A9和更新的GPU，2D纹理的最大大小为16384×16384.

For A9 and newer GPUs running current versions of iOS/tvOS/iPadOS, the maximum size of a 2D texture is 16384×16384.
