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. 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. 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. glGet with argument GL_POINT_FADE_THRESHOLD_SIZE glGet with argument GL_POINT_SPRITE_COORD_ORIGIN glPointSize Copyright 1991-2006 Silicon Graphics, Inc.
