BILLARD-GL(6)							   Games Manual 						     BILLARD-GL(6)

NAME

       billard-gl - OpenGL billiards game

SYNOPSIS

       billard-gl [options]

DESCRIPTION

       This  manual  page  documents  the billard-gl program. This manual page was written for Debian because the original program does not have a
       manual page.

       billard-gl implements a game of 8- or 9-ball billiards, which you can play against the computer or a friend.  The general idea of billiards
       is to hit the coloured balls with the cue ball in such a way that these balls fall in one of the six pockets of the table.

OPTIONS

       -f  -fullscreen
	      switches to fullscreen mode (can currently not be changed from inside billard-gl itself)

       -f  -windowed
	      switches to windowed mode (default; can currently not be changed from inside billard-gl itself)

       -t VALUE
	      texture size for the balls.  Valid values are 1 for full size textures, 2 for half size textures, 4 for quarter size textures, and 8
	      for eighth size textures.

       -tt VALUE
	      texture size for the table.  Valid values are 1 for full size textures, 2 for half size textures, 4 for quarter size textures, 8 for
	      eighth size textures, and 0 for no textures.

       -at VALUE
	      texture size for the display.  Valid values are 1 for full size textures and 2 for halfsized textures.

       -g VALUE
	      ball geometry; odd numbers >= 3.	Higher values create more complex geometry.

       To run billard-gl with minimum settings, try

	      billard-gl -t 8 -tt 0 -at 2 -g 3

       or for maximum settings, try

	      billard-gl -t 1 -tt 1 -at 1 -g 11

       All of the options are configurable from within billard-gl itself, unless stated otherwise.

NAME

       glPrioritizeTextures - set texture residence priority

C SPECIFICATION

       void glPrioritizeTextures( GLsizei n,
				  const GLuint *textures,
				  const GLclampf *priorities )

PARAMETERS

       n	   Specifies the number of textures to be prioritized.

       textures    Specifies an array containing the names of the textures to be prioritized.

       priorities  Specifies  an  array  containing  the  texture priorities.  A priority given in an element of priorities applies to the texture
		   named by the corresponding element of textures.

DESCRIPTION

       glPrioritizeTextures assigns the n texture priorities given in priorities to the n textures named in textures.

       The GL establishes a ``working set'' of textures that are resident in texture memory.  These textures may be bound to a texture target much
       more  efficiently than textures that are not resident.  By specifying a priority for each texture, glPrioritizeTextures allows applications
       to guide the GL implementation in determining which textures should be resident.

       The priorities given in priorities are clamped to the range [0,1] before they are assigned.  0 indicates the lowest priority; textures with
       priority  0  are  least	likely to be resident.	1 indicates the highest priority; textures with priority 1 are most likely to be resident.
       However, textures are not guaranteed to be resident until they are used.

       glPrioritizeTextures silently ignores attempts to prioritize texture 0, or any texture name that does not correspond to	an  existing  tex-
       ture.

       glPrioritizeTextures  does not require that any of the textures named by textures be bound to a texture target.	glTexParameter may also be
       used to set a texture's priority, but only if the texture is currently bound.  This is the only way to set the priority of a  default  tex-
       ture.

NOTES

       glPrioritizeTextures is available only if the GL version is 1.1 or greater.

ERRORS

       GL_INVALID_VALUE is generated if n is negative.

       GL_INVALID_OPERATION  is  generated if glPrioritizeTextures is executed between the execution of glBegin and the corresponding execution of
       glEnd.

ASSOCIATED GETS

       glGetTexParameter with parameter name GL_TEXTURE_PRIORITY retrieves the priority of a currently bound texture.
