Can Vertex Array Objects (VAOs) be shared across EAGLContexts in OpenGL ES?

Question

Spoiler: I\'m fairly confident that the answer is NO, but that\'s only after a day of very frustrated debugging. Now I would like to know if that is indeed the

Answer 1

According to this, OpenGL-ES explicitly disallows sharing of VAO objects:

Should vertex array objects be sharable across multiple OpenGL ES contexts?

RESOLVED: No. The OpenGL ES working group took a straw-poll and agreed that compatibility with OpenGL and ease of implementation were more important than creating the first non-shared named object in OpenGL ES.

As you noted, VBOs are still shareable, so you just have to create a VAO for each context that binds the shared VBO.
