Title: Quick question about OpenGL
Post by: z64555 on September 19, 2011, 03:11:57 pm

I REALLY have no idea which forum this should be in, so I'm sorry if I pissed off a mod or two.  :nervous:

Ok, I recently enrolled in a Computer Graphics class for the heck of it, and somehow got around to wondering what versions of OpenGL the latest version of FSO uses.

Well.

OpenGL support in FSO is a bit of an issue. We're currently technically using OpenGL 2, with a few bits and pieces (namely our shader support) relying on capabilities present in OpenGL 3 hardware.

Also note that, in a pinch, you can run FSO with a minimum OGL version of 1.4.

Many thanks, The E.

I was looking at the OGL website the other day and noticed they already specified OGL 4.2... sheesh. I don't know if I can keep up with technology anymore.

Well, if you're planning on studying it, I would recommend starting with OpenGL 3. Version 3 did a lot of restructuring of the API, and how it works behind the scenes; OGL 4 are incremental upgrades on that.

Also, OGL 4.2 is supported on Radeon 5k series cards and higher (although not by the standard drivers yet), I think the same goes for the equivalent nvidia hardware.
