I would like to create a thread for offline rendering with its own OpenGL context.
For submitting rendering tasks, I would like to use GCD, due to its API simplicity.
Is it possible to create a GCD queue that is attached to a specific NSThread (which has its own OpenGL context)?
It seems to be possible, since the main queue always runs it tasks on the main thread, but I could not find anything with similar behavior for custom threads.
You can set the current context at the beginning of every task, as described here: "OpenGL Restricts Each Context to a Single Thread" .
You can also set a context for the dispatch queue, as explained here .
