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
