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.
