OpenGL Extensions, Conﬁguring Swap Barriers | Nvidia 2 instruction

Using the OpenGL Extensions

Conﬁguring Swap Barriers

You can bind a group to a barrier. There is a maximum number of barriers that can be created. With the current hardware, the maximum number of barriers is one.

To determine the maximum barrier number, call

QueryMaxSwapGroupsNV()

To bind a group to a barrier, call

BindSwapBarrierNV()

and specify the group and barrier numbers.

If the barrier number is zero, then the group in unbound from the current barrier.

To query the current barrier, call QuerySwapGroupNV().

OpenGL Extensions

This section describes the relevant OpenGL NV_swap_group extensions supported by the NVIDIA display driver and shipped with the Quadro G-Sync II hardware.

These are exported in the WGL extension string which on Windows can be queried by wglGetExtensionsStringARB.

This section covers both the WGL_NV_swap_group extensions (exported on Microsoft WindowsNT/XP systems) and the GLX_NV_swap_group extensions (exported on Linux systems).
