.SH "NAME"
glPointSize \- specify the diameter of rasterized points
.SH "C SPECIFICATION"
.HP \w'void\ glPointSize('u
.BI "void glPointSize(GLfloat\ " "size" ");"
.SH "PARAMETERS"
.PP
\fIsize\fR
.RS 4
Specifies the diameter of rasterized points\&. The initial value is 1\&.
.RE
.SH "DESCRIPTION"
.PP

\fBglPointSize\fR
specifies the rasterized diameter of points\&. If point size mode is disabled (see
\fBglEnable\fR()
with parameter
\fBGL_PROGRAM_POINT_SIZE\fR), this value will be used to rasterize points\&. Otherwise, the value written to the shading language built\-in variable
gl_PointSize
will be used\&.
.SH "NOTES"
.PP
The point size specified by
\fBglPointSize\fR
is always returned when
\fBGL_POINT_SIZE\fR
is queried\&. Clamping and rounding for points have no effect on the specified value\&.
.SH "ERRORS"
.PP

\fBGL_INVALID_VALUE\fR
is generated if
\fIsize\fR
is less than or equal to 0\&.
