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
