Description
glPointSize
specifies the rasterized diameter of points. If point size mode
is disabled (see
glEnable
with parameter
GL_PROGRAM_POINT_SIZE
), this value will be used to rasterize points. Otherwise,
the value written to the shading language built-in variable
gl_PointSize
will be used.
Notes
The point size specified by
glPointSize
is always returned when
GL_POINT_SIZE
is queried. Clamping and rounding for points have no effect on the specified value.
Errors
GL_INVALID_VALUE
is generated if
size
is less than or equal to 0.
