I'm getting pretty confused about what state is really element buffer binding.
According to my experience it is VAO state thus switching VAOs also switches element array buffer binding.
However, I'm now confused because AFAIK the GL spec language does not state this anywhere.
It says the following about what VAOs encapsulate:
Also, I did not found in the GL core spec 4.1 any binding like ELEMENT_ARRAY_BUFFER_BINDING for them as it was ELEMENT_ARRAY_BUFFER_BINDING_ARB in the GL_ARB_vertex_buffer_object.The currently bound vertex array object is used for all commands which modify
vertex array state, such as VertexAttribPointer and EnableVertexAttribArray;
all commands which draw from vertex arrays, such as DrawArrays and DrawEle-
ments; and all queries of vertex array state (see chapter 6).
Can anybody clarify this to me?
Why there is no explicit wording about it in the spec?
