{{PageDescription}}
|
|
|
|
'''_glPointSize''' specifies the rasterized diameter of points. If point size mode is disabled (see {{KW|_glEnable}} with parameter {{KW|_GL_PROGRAM_POINT_SIZE}}), this value will be used to rasterize points. Otherwise, the value written to the shading language built-in variable {{code|gl_PointSize}} will be used.
|
|
|
|
|
|
{{PageNotes}}
|
|
|
|
The point size specified by '''_glPointSize''' is always returned when {{KW|_GL_POINT_SIZE}} is queried. Clamping and rounding for points have no effect on the specified value.
|
|
|
|
|
|
{{PageErrors}}
|
|
|
|
{{KW|_GL_INVALID_VALUE}} is generated if {{Parameter|size}} is less than or equal to 0.
