+ 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
.
