GLPOINTSIZE(3G) [FIXME: manual] GLPOINTSIZE(3G)
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.
