Note
This class was introduced in Qt 4.6
The PySide.QtGui.QVector4D class represents a vector or vertex in 4D space.
The PySide.QtGui.QVector4D class can also be used to represent vertices in 4D space. We therefore do not need to provide a separate vertex class.
Parameters: |

Constructs a null vector, i.e. with coordinates (0, 0, 0, 0).
Constructs a vector with x and y coordinates from a 2D point , and z and w coordinates of 0.
Constructs a vector with x and y coordinates from a 2D point , and z and w coordinates of 0.
Constructs a 4D vector from the specified 2D vector . The z and w coordinates are set to zero.

Parameters: |
|
---|---|
Return type: | PySide.QtCore.qreal |
Returns the dot product of v1 and v2 .
Return type: | PySide.QtCore.bool |
---|
Returns true if the x, y, z, and w coordinates are set to 0.0, otherwise returns false.
Return type: | PySide.QtCore.qreal |
---|
Returns the length of the vector from the origin.
Return type: | PySide.QtCore.qreal |
---|
Returns the squared length of the vector from the origin. This is equivalent to the dot product of the vector with itself.
Normalizes the currect vector in place. Nothing happens if this vector is a null vector or the length of the vector is very close to 1.
Return type: | PySide.QtGui.QVector4D |
---|
Returns the normalized unit vector form of this vector.
If this vector is null, then a null vector is returned. If the length of the vector is very close to 1, then the vector will be returned as-is. Otherwise the normalized form of the vector of length 1 will be returned.
