OpenGL - Where is the state set by glDrawBuffers stored?

If I understand correctly, you can attach textures to an FBO and then use glDrawBuffers to link those attachment points to (fragment) shader output indices. Where is this latter state stored after a glDrawBuffers call? The currently bound shader, FBO, or is it a global OpenGL state?

Solution

  • glDrawBuffer(s) sets framebuffer object state.
