Detailed Description
QwtPoint3D class defines a 3D point in double coordinates.
Constructor & Destructor Documentation
Constructs a null point.
- See also:
- isNull()
Copy constructor. Constructs a point using the values of the point specified.
Constructs a point with x and y coordinates from a 2D point, and a z coordinate of 0.
Member Function Documentation
- 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.
bool QwtPoint3D::operator!= |
( |
const QwtPoint3D & |
other | ) |
const [inline] |
- Returns:
- True if this rect and other are different; otherwise returns false.
bool QwtPoint3D::operator== |
( |
const QwtPoint3D & |
other | ) |
const [inline] |
- Returns:
- True, if this point and other are equal; otherwise returns false.
- Returns:
- A reference to the x-coordinate of the point.
- Returns:
- A reference to the y-coordinate of the point.
- Returns:
- A reference to the z-coordinate of the point.
- Returns:
- 2D point, where the z coordinate is dropped.
- Returns:
- The x-coordinate of the point.
- Returns:
- The y-coordinate of the point.
- Returns:
- The z-coordinate of the point.
