glPointSize — specify the diameter of rasterized points
void glPointSize( | GLfloat size) ; |
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.
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.
