Title: Split window to 2 parts
Post by: piotrekb on December 01, 2010, 03:07:09 pm

Hello!
I want to split my window to 2 parts: one for menu, and second for opengl rendering. What is the best way to make this in your opinion ?
And I have one more question: Can I draw sprites, when I use opengl ?

I think, you can find splitscreen functionality on the wiki. If you want to do it on your own, you have to use glScissor() directly in OpenGL.

Are you using sfml 2 ?

(I don't know if it's ok with native openGL)

Hmm... Is it possible to use SetViewport() multiple times per frame to achieve split screens?

I don't know, but in the doc, it's written that a global viewport is always made, so I think there's no problem ;) .

Okay. If it were possible, that would certainly be nice. It would also dispense with the need of raw OpenGL ;)
