Detailed 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.

Note: By design values in the QVector4D instance are stored as float. This means that on platforms where the qreal arguments to QVector4D functions are represented by double values, it is possible to lose precision.

See also QQuaternion, QVector2D, and QVector3D.

Member Function Documentation

virtual void QtGui.QVector4D.CreateProxy ( )

virtual

new void QtGui.QVector4D.Dispose

(

)

static double QtGui.QVector4D.DotProduct ( QVector4D  v1, QVector4D  v2  )

static

Returns the dot product of v1 and v2.

override bool QtGui.QVector4D.Equals

(

object

o

)

override int QtGui.QVector4D.GetHashCode

(

)

new bool QtGui.QVector4D.IsNull

(

)

Returns true if the x, y, z, and w coordinates are set to 0.0, otherwise returns false.

new double QtGui.QVector4D.Length

(

)

Returns the length of the vector from the origin.

See also lengthSquared() and normalized().

new double QtGui.QVector4D.LengthSquared

(

)

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() and dotProduct().

new void QtGui.QVector4D.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() and normalized().

new QVector4D QtGui.QVector4D.Normalized

(

)

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.

See also length() and normalize().

static

static QVector4D QtGui.QVector4D.operator* ( QVector4D  arg1, QVector4D  arg2  )

static

Returns the vector consisting of the multiplication of the components from v1 and v2.

See also QVector4D::operator*=().

static QVector4D QtGui.QVector4D.operator* ( QVector4D  arg1, QMatrix4x4  arg2  )

static

Returns a copy of the given vector, multiplied by the given factor.

See also QVector4D::operator*=().

static QVector4D QtGui.QVector4D.operator* ( QVector4D  arg1, double  arg2  )

static

Returns a copy of the given vector, multiplied by the given factor.

See also QVector4D::operator*=().

static QVector4D QtGui.QVector4D.operator+ ( QVector4D  arg1, QVector4D  arg2  )

static

Returns a QVector4D object that is the sum of the given vectors, v1 and v2; each component is added separately.

See also QVector4D::operator+=().

static QVector4D QtGui.QVector4D.operator- ( QVector4D  arg1 )

static

This is an overloaded function.

Returns a QVector4D object that is formed by changing the sign of all three components of the given vector.

Equivalent to QVector4D(0,0,0,0) - vector.

static QVector4D QtGui.QVector4D.operator- ( QVector4D  arg1, QVector4D  arg2  )

static

Returns a QVector4D object that is formed by subtracting v2 from v1; each component is subtracted separately.

See also QVector4D::operator-=().

static QVector4D QtGui.QVector4D.operator/ ( QVector4D  arg1, double  arg2  )

static

Returns the QVector4D object formed by dividing all four components of the given vector by the given divisor.
