Title: OpenGL with no or hidden window
Post by: ronag on September 20, 2010, 09:54:01 pm

I'm using SMFL to do some gpgpu computing... which doesnt require a window however a ogl context is still needed.

In what ways can I run OpenGL SFML with no or someway hidden window?

With SFML there's always an OpenGL context activated in the main thread, you don't have to do anything.

And if the main is unavailable... how do I add an ogl context to a new thread without creating a window?

Code: [Select]

sf::Context context;

Thanks. Almost there.

One last problem. How do I swap buffers using the context? It seems to create a dummy window in the background. However it is a private member and I cannot call Display on it.

EDIT: Solved, I'm just overthinking things.

Thanks for the help.
