GLPOINTPARAMETER(3G)            [FIXME: manual]           GLPOINTPARAMETER(3G)

NAME
       glPointParameter - specify point parameters

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

       void glPointParameteri(GLenum pname, GLint param);

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

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

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

       param
           For glPointParameterf and glPointParameteri, specifies the value
           that pname will be set to.

       params
           For glPointParameterfv and glPointParameteriv, specifies a pointer
           to an array where the value or values to be assigned to pname are
           stored.

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
