NAME¶

glutSwapBuffers — Swaps the buffers for the current window.

LIBRARY¶

OpenGLUT - window

SYNOPSIS¶

#include <openglut.h>

void
glutSwapBuffers(void);

DESCRIPTION¶

This function signals to OpenGLUT that you are done drawing to the

current window

for now. If your window is double-buffered (

GLUT_DOUBLE

param to glutInitDisplayMode()), then OpenGLUT will swap the front buffer with the back buffer.

This also computes your current frame-rate and prints the result on

stderr

if indicated by the

GLUT_FPS

environment variable. The computed value is not necessarily the total frame rate, if you have multiple windows, as the statistic is the total number of buffer-swaps for the entire program.

CAVEATS¶

This function has no effect if your window is

GLUT_SINGLE

Frame rate is only calculated for double-buffered windows.

TODO¶

How does this interact with overlays?
