How to manage drivers and OpenGL acceleration

[pa1]

Hello y'all,

I need to know if there is a way (programming of course):

1) to detect and display the installed drivers on the system (Windows),

2) if there is a way to know if OpenGL (or vtk) is accelerated by software or hardware in any pc

3) and how, if possible, to change from the hardware acceleration to the software one and vice versa (with a program made by me, again).

Thank you.

What exactly do you want to do with this?

I want to know if my OpenGL or vtk application will run in any PC, and if it doesn't, to identify if it's a problem related to the video card and therefore adapt the application to run under OpenGL software acceleration. Or because the system needs some specific drivers to be installed. For example, I have a vtk program which regards to graphics in some PCs looks pretty good, but in others not. So, in the ones that doesn't look good, I would like to tell the user to install the specific driver the program needs to look good (or to at least run decently).
Thank you again.:lol:
