        .PP pname

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

            .RE
            .PP param

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

                .PP params

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

                .SH "DESCRIPTION"
                    .PP The following values are accepted for pname:

                        .PP 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.

                            .PP 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.

                            .PP GL_INVALID_VALUE is generated if the value specified for GL_POINT_FADE_THRESHOLD_SIZE is less than zero.
                            .PP GL_INVALID_ENUM is generated If the value specified for GL_POINT_SPRITE_COORD_ORIGIN is not GL_LOWER_LEFT or GL_UPPER_LEFT.
