glutSwapBuffers(3GLUT) GLUT glutSwapBuffers(3GLUT)NAMEglutSwapBuffers - swaps the buffers of the current window
if double buffered.
SYNTAX
void glutSwapBuffers(void);
DESCRIPTION
Performs a buffer swap on the layer in use for the current
window. Specifically, glutSwapBuffers promotes the con
tents of the back buffer of the layer in use of the cur
rent window to become the contents of the front buffer.
The contents of the back buffer then become undefined. The
update typically takes place during the vertical retrace
of the monitor, rather than immediately after glutSwap
Buffers is called.
An implicit glFlush is done by glutSwapBuffers before it
returns. Subsequent OpenGL commands can be issued immedi
ately after calling glutSwapBuffers, but are not executed
until the buffer exchange is completed.
If the layer in use is not double buffered, glutSwap
Buffers has no effect.
