glPointSize — specify the diameter of rasterized points
void glPointSize( | GLfloat size); |
size Specifies the diameter of rasterized points. The initial value is 1.
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.
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.
GL_INVALID_VALUE is generated if size is less than or equal to 0.
