Member Function Documentation
  
  | 
        
          | bool QwtPoint3D::isNull | ( |  | ) | const |  | inline | 
 
Returns true if the point is null; otherwise returns false.
A point is considered to be null if x, y and z-coordinates are equal to zero.

          | QPointF QwtPoint3D::toPoint | ( |  | ) | const |  | inline | 
 
Rounds 2D point, where the z coordinate is dropped.
