QVector4D

PyQt5.QtGui.QVector4D

Description

The QVector4D class represents a vector or vertex in 4D space.

The QVector4D class can also be used to represent vertices in 4D space. We therefore do not need to provide a separate vertex class.

QQuaternion, QVector2D, QVector3D.

__init__(QVector2D)

Constructs a 4D vector from the specified 2D vector. The z and w coordinates are set to zero.

toVector2D().

---

__init__(QVector3D)

Constructs a 4D vector from the specified 3D vector. The w coordinate is set to zero.

length() → float

Returns the length of the vector from the origin.

lengthSquared(), normalized().

---

lengthSquared() → float

Returns the squared length of the vector from the origin. This is equivalent to the dot product of the vector with itself.

See also

length(), dotProduct().

normalize()

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.

See also

length(), normalized().

---

normalized() → 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.

toVector2DAffine(), toVector3D(), toPoint().

---

toVector2DAffine() → QVector2D

Returns the 2D vector form of this 4D vector, dividing the x and y coordinates by the w coordinate and dropping the z coordinate. Returns a null vector if w is zero.

toVector2D(), toVector3DAffine(), toPoint().

---

toVector3D() → QVector3D

Returns the 3D vector form of this 4D vector, dropping the w coordinate.

---

toVector3DAffine() → QVector3D

Returns the 3D vector form of this 4D vector, dividing the x, y, and z coordinates by the w coordinate. Returns a null vector if w is zero.
