哪些GLSL ES扩展在各种iOS设备上可用? [英] Which GLSL ES extensions are available on various iOS devices?

问题描述

我正在寻找所有iOS设备上可用的所有扩展(以及哪些设备上可用的扩展)的列表.尽管进行了大量搜索，但我在Apple文档中找不到正确的页面，但是我敢肯定它在某个地方.有指针吗?

I'm looking for a list of all extensions available on any iOS devices (and which are available on which device). I haven't found the right page in the apple docs despite a lot of searching, but I'm sure it's there somewhere. Any pointers?

推荐答案

此代码应打印出所有扩展名:

This code should print out all extensions:

NSString *extensionString = [NSString stringWithUTF8String:(char *)glGetString(GL_EXTENSIONS)];
NSArray *extensions = [extensionString componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
for (NSString *oneExtension in extensions)
    NSLog(@"%@", oneExtension);
