Which OpenGL version is installed?
- by René Nyffenegger
I recently tried to lay my hands on OpenGL. Trying to grasp the API, I learned (or was given the advice) that I shouldn't use glBegin and glEnd anymore, since those are deprecated, but should start with OpenGL 3.1, instead. As I didn't know that the version used makes such a difference, I didn't pay much attention as to which version I actually have installed on my computer. And, as far as I can see, there is no glVersion or similar call that I could use to determine that version.
I am using MinGW and I found the following lines in c:\MinGW\include\GL\gl.h:
/*
* Mesa 3-D graphics library
* Version: 4.0
[more lines]
*/
[more lines]
#define GL_VERSION_1_1 1
#if !defined(__WIN32__)
#define GL_VERSION_1_2 1
#define GL_VERSION_1_3 1
#define GL_ARB_imaging 1
#endif
[more lines]
#define GL_VERSION 0x1F02
which, to me, indicates, that the installed version is as low as 1.3. Is this the case or how could I verify my suspicion? Also, where would I find a later version if I have 1.3 only?
