Detailed Description

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

Vectors are one of the main building blocks of 3D representation and drawing. They consist of three 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.

Note: By design values in the QVector3D instance are stored as float. This means that on platforms where the qreal arguments to QVector3D functions are represented by double values, it is possible to lose precision.

See also QVector2D, QVector4D, and QQuaternion.

Member Function Documentation

virtual void QtGui.QVector3D.CreateProxy ( )

virtual

static QVector3D QtGui.QVector3D.CrossProduct ( QVector3D  v1, QVector3D  v2  )

static

Returns the cross-product of vectors v1 and v2, which corresponds to the normal vector of a plane defined by v1 and v2.

See also normal().

new void QtGui.QVector3D.Dispose

(

)

new double QtGui.QVector3D.DistanceToLine	(	QVector3D	point,
		QVector3D	direction
	)

Returns the distance that this vertex is from a line defined by point and the unit vector direction.

If direction is a null vector, then it does not define a line. In that case, the distance from point to this vertex is returned.

See also distanceToPlane().

new double QtGui.QVector3D.DistanceToPlane	(	QVector3D	plane,
		QVector3D	normal
	)

Returns the distance from this vertex to a plane defined by the vertex plane and a normal unit vector. The normal parameter is assumed to have been normalized to a unit vector.

The return value will be negative if the vertex is below the plane, or zero if it is on the plane.

See also normal() and distanceToLine().

new double QtGui.QVector3D.DistanceToPlane	(	QVector3D	plane1,
		QVector3D	plane2,
		QVector3D	plane3
	)

This is an overloaded function.

Returns the distance from this vertex a plane defined by the vertices plane1, plane2 and plane3.

The return value will be negative if the vertex is below the plane, or zero if it is on the plane.

The two vectors that define the plane are plane2 - plane1 and plane3 - plane1.

See also normal() and distanceToLine().

static double QtGui.QVector3D.DotProduct ( QVector3D  v1, QVector3D  v2  )

static

Returns the dot product of v1 and v2.

override bool QtGui.QVector3D.Equals

(

object

o

)

override int QtGui.QVector3D.GetHashCode

(

)

new bool QtGui.QVector3D.IsNull

(

)

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

new double QtGui.QVector3D.Length

(

)

Returns the length of the vector from the origin.

See also lengthSquared() and normalized().

new double QtGui.QVector3D.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().

static QVector3D QtGui.QVector3D.Normal ( QVector3D  v1, QVector3D  v2  )

static

Returns the normal vector of a plane defined by vectors v1 and v2, normalized to be a unit vector.

Use crossProduct() to compute the cross-product of v1 and v2 if you do not need the result to be normalized to a unit vector.

See also crossProduct() and distanceToPlane().

static QVector3D QtGui.QVector3D.Normal ( QVector3D  v1, QVector3D  v2, QVector3D  v3  )

static

This is an overloaded function.

Returns the normal vector of a plane defined by vectors v2 - v1 and v3 - v1, normalized to be a unit vector.

Use crossProduct() to compute the cross-product of v2 - v1 and v3 - v1 if you do not need the result to be normalized to a unit vector.

See also crossProduct() and distanceToPlane().

new void QtGui.QVector3D.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 QVector3D QtGui.QVector3D.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 QVector3D QtGui.QVector3D.operator* ( QVector3D  arg1, QVector3D  arg2  )

static QVector3D QtGui.QVector3D.operator- ( QVector3D  arg1 )
