GLPOINTSIZE(3G)                                  OpenGL 3.3                                  GLPOINTSIZE(3G)



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.
