OpenGL Extensions
This section describes the relevant OpenGL extensions supported by the NVIDIA display
driver (to be shipped with the NVIDIA frame-lock hardware). The set of extensions
supported for frame lock are exported as
WGL_I3D_genlock
and
WGL_NV_swap_group
.
These are exported in the WGL extension string which can be queried by
wglGetExtensionsStringARB
. This documentation covers the WGL versions of the
extensions which are exported on Microsoft WindowsNT/XP systems. There is an
equivalent Unix version of these extensions:
GLX_NV_swap_group
.
