GLPOINTPARAMETER(3G)		 OpenGL Manual		  GLPOINTPARAMETER(3G)

NAME
       glPointParameter - specify point parameters

C SPECIFICATION
       void glPointParameterf(GLenum pname, GLfloat param);

       void glPointParameteri(GLenum pname, GLint param);

PARAMETERS
       pname
	   Specifies a single-valued point parameter.
	   GL_POINT_FADE_THRESHOLD_SIZE, and GL_POINT_SPRITE_COORD_ORIGIN are
	   accepted.

       param
	   Specifies the value that pname will be set to.

C SPECIFICATION
       void glPointParameterfv(GLenum pname, const GLfloat * params);

       void glPointParameteriv(GLenum pname, const GLint * params);

PARAMETERS
       pname
	   Specifies a point parameter.	 GL_POINT_FADE_THRESHOLD_SIZE, and
	   GL_POINT_SPRITE_COORD_ORIGIN are accepted.

       params
	   Specifies the value to be assigned to pname..

DESCRIPTION
       The following values are accepted for pname:

       GL_POINT_FADE_THRESHOLD_SIZE

	   params is a single floating-point value that specifies the
	   threshold value to which point sizes are clamped if they exceed the
	   specified value. The default value is 1.0.

       GL_POINT_SPRITE_COORD_ORIGIN

	   params is a single enum specifying the point sprite texture
	   coordinate origin, either GL_LOWER_LEFT or GL_UPPER_LEFT. The
	   default value is GL_UPPER_LEFT.

ERRORS
       GL_INVALID_VALUE is generated if the value specified for
       GL_POINT_FADE_THRESHOLD_SIZE is less than zero.

       GL_INVALID_ENUM is generated If the value specified for
       GL_POINT_SPRITE_COORD_ORIGIN is not GL_LOWER_LEFT or GL_UPPER_LEFT.

ASSOCIATED GETS
       glGet() with argument GL_POINT_FADE_THRESHOLD_SIZE

       glGet() with argument GL_POINT_SPRITE_COORD_ORIGIN
