Hi, Currently i am working in OpenGL 1.1, now i like to upgrade to OpenGL 1.2 What are all the things i need to do for upgradation. While installing VC++6.0, OpenGL 1.1 is installed. Where can i get the Version 1.2 and what are all the changes i need to do for upgrading my version. Regards, Rajesh C

I think most probably u'll need this for extension: glew

for glversion: glext

You don't have to upgrade like that. Version 2.0 is most probably allready implemented in the drivers of your 3Dcard. You just have to gain acces to its functions and tokens. [google] for opengl extensions for an explanation

Good Luck!

Hi All,
Lot of thanks for your valuable response. I was trying with the following code after including the glext.h in my file. I am having problem in using the same in my project. Actually after executing the following code,

PFNGLGETCOLORTABLEEXTPROC pglColorTableEXT = NULL;
pglColorTableEXT = (PFNGLGETCOLORTABLEEXTPROC) wglGetProcAddress("glGetColorTableEXT");


I am getting always NULL for the variable "pglColorTableEXT". What could be the reason. Is that my Pc is not supporting this extension or we need to do change some settings in my PC.

Same problem araise for the below mentioned APIs also:
PFNGLCOLORSUBTABLEPROC
PFNGLCOLORSUBTABLEEXTPROC
PFNGLMULTITEXCOORD2FARBPROC

Also above problem is not reflecting in all PC. Could be please give me a solution for the above problem.

Delphi3D provides an excellent utility to test which extensions are supported by your current card/driver combo. It is called GLinfo and here's a direct link to the download, download (394Kb).

Sorry for the brief reply but I'm in a rush, hope that helps though!
