GlPointSize

_glPointSize: specify the diameter of rasterized points

Syntax

 SUB _glPointSize (BYVAL size AS SINGLE)
 void _glPointSize(GLfloat size);

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 Template:Code 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.

Use With:

_glGet with argument _GL_POINT_SIZE_RANGE

_glGet with argument _GL_POINT_SIZE_GRANULARITY

_glGet with argument _GL_POINT_SIZE

_glGet with argument _GL_POINT_SIZE_MIN

_glGet with argument _GL_POINT_SIZE_MAX

_glGet with argument _GL_POINT_FADE_THRESHOLD_SIZE

_glIsEnabled with argument _GL_PROGRAM_POINT_SIZE
