Be warned: this is probably a total neophyte question
I just read in The Red Book (1.2/3rd), that “vertex sharing” is not supported in all OpenGL implementations (in the section “Vertex Arrays”). So, my question is: If an OpenGL program I have made for Windows (using WGL) works on my computer, will it work on all Windows computers? Or, in other words: Do all Windows systems use the same implementation, or does it depend on the hardware/driver/somethingElse?
Thanks in advance
Every 3d chip/card vendor needs to license this own OpenGL implementstion.
I hope this answers your question.
Yeah, it does.
I found out that you can get the version used by the system with glGetString ( GL_VERSION ). The default version in Windows is 1.1, but if you need to access function in the driver/on the card (extensions), simply get the address with wglGetProcAddress.
Thanks for your reply.
