NAME
glutEnterGameMode, glutLeaveGameMode - enters and leaves GLUT's game mode. SYNTAX
#include <GLUT/glut.h> void glutEnterGameMode(void); void glutLeaveGameMode(void); DESCRIPTION
glutEnterGameMode is designed to enable high-performance fullscreen GLUT rendering, possibly at a different screen display format. Calling glutEnterGameMode creates a special fullscreen GLUT window (with its own callbacks and OpenGL rendering context state). If the game mode string describes a possible screen display format, GLUT also changes the screen display format to the one described by the game mode string. glutLeaveGameMode leaves the GLUT game mode and returns the screen display format to its default format. When game mode is entered, certain GLUT functionality is disable to facilitate high-performance fullscreen rendering. GLUT pop-up menus are not available while in game mode. Other created windows and subwindows are not displayed in GLUT game mode. Game mode will also hide all other applications running on the computer's display screen. The intent of these restrictions is to eliminate window clipping issues, permit screen display format changes, and permit fullscreen rendering optimization such as page flipping for fullscreen buffer swaps. After leaving game mode, the GLUT functionality disabled in game mode is available again. The game mode window (and its OpenGL rendering state) is destroyed when leaving game mode. Any windows and subwindows created before entering the game mode are displayed in their previ- ous locations. The OpenGL state of normal GLUT windows and subwindows is not disturbed by entering and/or leaving game mode. The following GLUT routines are ignored in game mode: glutFullScreen, glutSetWindowTitle, glutSetIconTitle, glutPositionWindow, glutRe- shapeWindow, glutPopWindow, glutPushWindow, glutIconifyWindow, glutShowWindow, glutHideWindow. glutEnterGameMode can be called when already in game mode. This will destroy the previous game mode window (including any OpenGL rendering state) and create a new game mode window with a new OpenGL rendering context. Also if glutEnterGameMode is called when already in game mode and if the game mode string has changed and describes a possible screen display format, the new screen display format takes effect. A reshape callback is generated if the game mode window changes size due to a screen display format change. Re-entering game mode provides a mechanism for changing the screen display format while already in game mode. Note though that the game mode window's OpenGL state is lost in this process and the application is responsible for re-initializing the newly created game mode win- dow OpenGL state when re-entering game mode. Game mode cannot be entered while pop-up menus are in use. Note that the glutEnterGameMode and glutFullScreen routines operate differently. glutFullScreen simply makes the current window match the size of the screen. glutFullScreen does not change the screen display format and does not disable any GLUT features such as pop-up menus; glutFullScreen continues to operate in a "windowed" mode of operation. glutEnterGameMode creates a new window style, possibly changes the screen display mode, limits GLUT functionality, and hides other applications.

NAME
stormbaancoureur - simulated obstacle course for automobiles SYNOPSIS
stormbaancoureur [options] DESCRIPTION
Your objective is to drive your car along an obstacle course. Success depends on total control of the car. If you want to master it, try to have the laws of physics work with you, not against you. OPTIONS
stormbaancoureur accepts the standard glutInit options for your system. The X Window System specific options parsed by glutInit are as follows: -display DISPLAY Specify the X server to connect to. If not specified, the value of the DISPLAY environment variable is used. -geometry W x H + X + Y Determines where window's should be created on the screen. The parameter following -geometry should be formatted as a standard X geometry specification. The effect of using this option is to change the GLUT initial size and initial position the same as if glu- tInitWindowSize or glutInitWindowPosition were called directly. -iconic Requests all top-level windows be created in an iconic state. -indirect Force the use of indirect OpenGL rendering contexts. -direct Force the use of direct OpenGL rendering contexts (not all GLX implementations support direct rendering contexts). A fatal error is generated if direct rendering is not supported by the OpenGL implementation. If neither -indirect or -direct are used to force a particular behavior, GLUT will attempt to use direct rendering if possible and otherwise fallback to indirect rendering. -gldebug After processing callbacks and/or events, check if there are any OpenGL errors by calling glGetError. If an error is reported, print out a warning by looking up the error code with gluErrorString. Using this option is helpful in detecting OpenGL run-time errors. -sync Enable synchronous X protocol transactions. This option makes it easier to track down potential X protocol errors. Debian-specific options: -fullscreen Run the game in fullscreen mode -window Run the game inside a window SEE ALSO
