Maybe you’ve heard of this already, but I thought it would be nice to
highlight this nice project: http://libgls.sourceforge.net/
LibGLS s a library that aims at simplifying stereo rendering of opengl
applications, games and software. Its API is lightweight and offers
quite a few 3D modes.
This library is the backend for bino (http://bino3d.org/), a powerful
opensource stereoscopic video player.
If you had in mind of adding 3D stereo support for your game, now you
have the tools
I wonder how much development effort would be to integrate something
like this in the SDL API…
