NAME

6       glPointSize - specify the diameter of rasterized points
7

C SPECIFICATION

9       void glPointSize(GLfloat size);
10

PARAMETERS

12       size
13           Specifies the diameter of rasterized points. The initial value is
14           1.
15

DESCRIPTION

17       glPointSize specifies the rasterized diameter of points. If point size
18       mode is disabled (see glEnable() with parameter GL_PROGRAM_POINT_SIZE),
19       this value will be used to rasterize points. Otherwise, the value
20       written to the shading language built-in variable gl_PointSize will be
21       used.
22

NOTES

24       The point size specified by glPointSize is always returned when
25       GL_POINT_SIZE is queried. Clamping and rounding for points have no
26       effect on the specified value.
27

ERRORS

29       GL_INVALID_VALUE is generated if size is less than or equal to 0.
