Using the OpenGL Extensions This chapter explains how to use the OpenGL extensions supported by the NVIDIA driver for accomplishing frame synchronization of applications. Frame Synchronization Using the OpenGL Extensions explains the principles behind swap groups, and describes the OpenGL extensions to use to control frame lock and swap sync functions. OpenGL Extensions details the API calls for the extensions.
NVIDIA Quadro G-Sync II User Guide Frame Synchronization Using the OpenGL Extensions Swap sync refers to the synchronization of buffer swaps of multiple application windows. By means of swap sync, applications running on multiple systems can synchronize the application buffer swaps between all the systems.
Using the OpenGL Extensions Buffer Swap Criteria The criteria for buffer swaps involves when a window is ready to swap and when a group is ready to swap. Window Buffer Swaps Any rendering surface that is not a window—such as a non-visible rendering buffer—is always ready, otherwise the following criteria must be satisfied before a buffer swap for a window can be performed: The window itself must be ready, meaning: A buffer swap command has been issued for it. Its swap interval has elapsed.
NVIDIA Quadro G-Sync II User Guide Frame Counter The implementation provides a universal counter, or frame counter, among all systems that are locked together by swap groups/barriers. It is based on the internal synchronization signal which triggers the buffer swap. To obtain the current frame count, call wglQueryFrameCountNV(),glxQueryFrameCountNV()(). To reset the frame count back to zero, call, wglResetFrameCountNV(),glxResetFrameCountNV()().
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.
NVIDIA Quadro G-Sync II User Guide wglJoinSwapGroupNV(), glxJoinSwapGroupNV() This call adds the OpenGL window with the device context hDC to the swap group specified by group. If hDC is already a member of a different group, it is implicitly removed from that group first. Function B00L JoinSwapGroupNV (HDC hDC, GLuint group); Parameters In hDC - Device context for the frame lock card, or a window residing on the frame lock card. group - Swap group number to which the device context is to be assigned.
Using the OpenGL Extensions wglQuerySwapGroupNV(), glxQuerySwapGroupNV() This call returns the swap group number and barrier number to which the device context is bound. Function B00L QuerySwapGroupNV (HDC hDC, GLuint *group, GLuint *barrier); Parameters In hDC - Device context for the frame lock card, or a window residing on the frame lock card. Parameters Out *group - The group number to which the device context is bound, or assigned.
NVIDIA Quadro G-Sync II User Guide wglQueryFrameCountNV(),glxQueryFrameCount NV() QueryFrameCountNV returns in count the current frame counter for swapGroup. This call returns the current frame count of the swap group. Function B00L QueryFrameCountNV (HDC hDC, GLuint *carrier); Parameters In hDC - Device context for the frame lock card, or a window residing on the frame lock card. Parameters Out *count - The current frame count of the swap group.
