NAME¶
glPointParameter - specify point parametersC 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¶
pnameSpecifies 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¶
