Detailed Description

The QVector3D class represents a vector or vertex in 3D space.

Since: 4.6

\inmodule QtGui

Vectors are one of the main building blocks of 3D representation and drawing. They consist of three finite floating-point coordinates, traditionally called x, y, and z.

The QVector3D class can also be used to represent vertices in 3D space. We therefore do not need to provide a separate vertex class.

friend QVector3D operator/	(	QVector3D	vector,
		float	divisor )

friend

//!

friend

Returns the QVector3D object formed by dividing each component of the given vector by the given divisor.

The divisor must not be either zero or NaN.

Definition at line 270 of file qvectornd.h.

◆ operator/ [2/2]

friend QVector3D operator/	(	QVector3D	vector,

friend

//!

friend

Since: 5.5

Returns the QVector3D object formed by dividing each component of the given vector by the corresponding component of the given divisor.

The divisor must have no component that is either zero or NaN.

Definition at line 276 of file qvectornd.h.

◆ operator<<()

QDataStream & operator<<	(	QDataStream &	stream,
		QVector3D	vector )

Writes the given vector to the given stream and returns a reference to the stream.

Definition at line 1079 of file qvectornd.cpp.

References x(), y(), and z().

Here is the call graph for this function:

◆ operator==

QT_WARNING_PUSH QT_WARNING_DISABLE_FLOAT_COMPARE constexpr friend bool operator==	(	QVector3D	v1,
		QVector3D	v2 )

friend

Returns true if v1 is equal to v2; otherwise returns false.

This operator uses an exact floating-point comparison.

Definition at line 224 of file qvectornd.h.

◆ operator>>()

QDataStream & operator>>	(	QDataStream &	stream,
		QVector3D &	vector )

Reads a 3D vector from the given stream into the given vector and returns a reference to the stream.

See also: {Serializing Qt Data Types}

References setX(), setY(), and setZ().

Here is the call graph for this function:

◆ qFuzzyCompare

Q_GUI_EXPORT bool qFuzzyCompare	(	QVector3D	v1,
		QVector3D	v2 )

friend

//!

friend

Returns true if v1 and v2 are equal, allowing for a small fuzziness factor for floating-point comparisons; false otherwise.
