更改顶点数组对象

Question

让我们看看这段代码：

glGenVertexArrays(1, &name);
glBindVertexArray(name);

glBindBuffer(GL_ARRAY_BUFFER, someBuffer1);
glVertexAttribPointer(...);

(...)

glBindBuffer(GL_ARRAY_BUFFER, someBuffer2);
glVertexAttribPointer(...);

(...)

glBindVertexArray(0);

如果我决定做这样的事情，会发生什么：

glBindVertexArray(name);

glBindBuffer(GL_ARRAY_BUFFER, someBuffer3);
glVertexAttribPointer(...);

(...)

glBindBuffer(GL_ARRAY_BUFFER, someBuffer4);
glVertexAttribPointer(...);

(...)

glBindVertexArray(0);

？ 我可以这样改变顶点声明布局吗？有办法做到吗？
