+
+ Date: 5/1/2003 Revision: 1.1
+
+Number
+
+ OpenGL Extension #514
+
+Dependencies
+
+ None
+
+ Based on GLX_SGI_swap_control version 1.9 and WGL_EXT_swap_control
+ version 1.5.
+
+Overview
+
+ This extension allows an application to specify a minimum periodicity
+ of color buffer swaps, measured in video frame periods.
+
+Issues
+
+ * Should implementations that export GLX_MESA_swap_control also export
+ GL_EXT_swap_control for compatibility with WGL_EXT_swap_control?
+
+ UNRESOLVED.

+
+ [Add the following to Section 3.3.10 of the GLX Specification (Double
+ Buffering)]
+
+ glXSwapIntervalMESA specifies the minimum number of video frame periods
+ per buffer swap. (e.g. a value of two means that the color buffers
+ will be swapped at most every other video frame.) A return value
+ of zero indicates success; otherwise an error occurred. The interval
+ takes effect when glXSwapBuffers is first called subsequent to the
+ glXSwapIntervalMESA call.
+
+ A video frame period is the time required by the monitor to display a
+ full frame of video data. In the case of an interlaced monitor,
+ this is typically the time required to display both the even and odd
+ fields of a frame of video data.
+
+ If <interval> is set to a value of 0, buffer swaps are not synchro-
+ nized to a video frame. The <interval> value is silently clamped to
+ the maximum implementation-dependent value supported before being
+ stored.
+
+ The swap interval is not part of the render context state. It cannot
+ be pushed or popped. The current swap interval for the window
+ associated with the current context can be obtained by calling
+ glXGetSwapIntervalMESA. The default swap interval is 0.
+
+ On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
+ the swap interval to 1.
+
+Errors
+
+ glXSwapIntervalMESA returns GLX_BAD_CONTEXT if there is no current
+ GLXContext or if the current context is not a direct rendering context.
+
+GLX Protocol
+
+ None. This extension only extends to direct rendering contexts.
