GLPOINTPARAMETER(3G)                             OpenGL 3.3                             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
