链接着色器程序之后，我们可以删除顶点着色器和片段着色器吗? [英] Can we delete vertex and fragment shaders after link shader program

问题描述

正如标题所述，我可以在程序中执行此操作吗?

As title said, Can I do this in my program:

vertex = glCreateShader(GL_VERTEX_SHADER);
/* ... */
fragment = glCreateShader(GL_FRAGMENT_SHADER);
/* ... */
program = glCreateProgram();
glAttachShader(program, vertex);
glAttachShader(program, fragment);
glLinkProgram(program);
/* All things done */

glDeleteShader(vertex); /* <~ Can I do this now? */
glDeleteShader(vertex); /* <~ Can I do this now? */

/* And in render procedure */
glUseProgram(program); /* <~ Still use program without any problem? */
/* ... */

推荐答案

是的，这完全有效.着色器对象仍由程序对象内部引用，并且在删除程序对象时将隐式释放它们.

Yes, this perfectly valid. Shader objects are still internally referenced by the program object and will be implicitly freed when the program object is deleted.
