glutpostredisplay(3) [centos man page]

glutPostRedisplay -- Mark the current window as needing a redisplay. LIBRARY
OpenGLUT - window SYNOPSIS
#include <openglut.h> void glutPostRedisplay(void); DESCRIPTION
Whenever circumstances indicate that your window is in need of being redisplayed, you may call glutPostRedisplay() to tell OpenGLUT that you want to redraw your graphics. Multiple calls to this function may be coalesced by OpenGLUT to avoid excessive invocation of your drawing support. The ultimate effect of this function is to call your Display callback for the current window . SEE ALSO

glutPostRedisplay, glutPostWindowRedisplay - marks the current or specified window as needing to be redisplayed. SYNTAX
void glutPostRedisplay(void); void glutPostWindowRedisplay(int win); DESCRIPTION
glutPostRedisplay marks the normal plane of current window as needing to be redisplayed. glutPostWindowRedisplay works the specified win- dow as needing to be redisplayed. After either call, the next iteration through glutMainLoop, the window's display callback will be called to redisplay the window's normal plane. Multiple calls to glutPostRedisplay before the next display callback opportunity generates only a single redisplay callback. glutPostRedisplay may be called within a window's display or overlay display callback to re-mark that window for redisplay. Logically, normal plane damage notification for a window is treated as a glutPostRedisplay on the damaged window. Unlike damage reported by the window system, glutPostRedisplay will not set to true the normal plane's damaged status (returned by glutLayerGet(GLUT_NORMAL_DAMAGED). If the window you want to post a redisplay on is not already current (and you do not require it to be immediately made current), using glutPostWindowRedisplay is more efficient that calling glutSetWindow to the desired window and then calling glutPostRedisplay.
