NAME

       glPointSize - specify the diameter of rasterized points

C SPECIFICATION

       void glPointSize(GLfloat size);

PARAMETERS

       size
           Specifies the diameter of rasterized points. The initial value is 1.

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.

       glGet() with argument GL_POINT_SIZE_GRANULARITY

       glGet() with argument GL_POINT_SIZE

       glGet() with argument GL_POINT_FADE_THRESHOLD_SIZE
