Detailed Description

The QQuaternion class represents a quaternion consisting of a vector and scalar.

Quaternions are used to represent rotations in 3D space, and consist of a 3D rotation axis specified by the x, y, and z coordinates, and a scalar representing the rotation angle.

Member Function Documentation

new QQuaternion QtGui.QQuaternion.Conjugate

(

)

Returns the conjugate of this quaternion, which is (-x, -y, -z, scalar).

virtual void QtGui.QQuaternion.CreateProxy ( )

new void QtGui.QQuaternion.Dispose

override bool QtGui.QQuaternion.Equals

object

o

)

static QQuaternion QtGui.QQuaternion.FromAxisAndAngle ( QVector3D  axis, double  angle  )

static

Creates a normalized quaternion that corresponds to rotating through angle degrees about the specified 3D axis.

static QQuaternion QtGui.QQuaternion.FromAxisAndAngle ( double  x, double  y, double  z, double  angle  )

static

Creates a normalized quaternion that corresponds to rotating through angle degrees about the specified 3D axis.

override int QtGui.QQuaternion.GetHashCode

(

)

new bool QtGui.QQuaternion.IsIdentity

(

)

Returns true if the x, y, and z components of this quaternion are set to 0.0, and the scalar component is set to 1.0; otherwise returns false.

new bool QtGui.QQuaternion.IsNull

(

)

Returns true if the x, y, z, and scalar components of this quaternion are set to 0.0; otherwise returns false.

new double QtGui.QQuaternion.Length

(

)

Returns the length of the quaternion. This is also called the "norm".

See also lengthSquared() and normalized().

new double QtGui.QQuaternion.LengthSquared

(

)

Returns the squared length of the quaternion.

See also length().

static QQuaternion QtGui.QQuaternion.Nlerp ( QQuaternion  q1, QQuaternion  q2, double  t  )

static

Interpolates along the shortest linear path between the rotational positions q1 and q2. The value t should be between 0 and 1, indicating the distance to travel between q1 and q2. The result will be normalized().

If t is less than or equal to 0, then q1 will be returned. If t is greater than or equal to 1, then q2 will be returned.

The nlerp() function is typically faster than slerp() and will give approximate results to spherical interpolation that are good enough for some applications.

See also slerp().

new void QtGui.QQuaternion.Normalize

(

)

Normalizes the currect quaternion in place. Nothing happens if this is a null quaternion or the length of the quaternion is very close to 1.

See also length() and normalized().

new QQuaternion QtGui.QQuaternion.Normalized

(

)

Returns the normalized unit form of this quaternion.

If this quaternion is null, then a null quaternion is returned. If the length of the quaternion is very close to 1, then the quaternion will be returned as-is. Otherwise the normalized form of the quaternion of length 1 will be returned.

See also length() and normalize().

static bool QtGui.QQuaternion.operator!= ( QQuaternion  arg1, QQuaternion  arg2  )

static

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

static

Multiplies q1 and q2 using quaternion multiplication. The result corresponds to applying both of the rotations specified by q1 and q2.

See also QQuaternion::operator*=().

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

static

Multiplies q1 and q2 using quaternion multiplication. The result corresponds to applying both of the rotations specified by q1 and q2.

See also QQuaternion::operator*=().

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

static

Returns a QQuaternion object that is the sum of the given quaternions, q1 and q2; each component is added separately.

See also QQuaternion::operator+=().

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

static

This is an overloaded function.

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

Equivalent to QQuaternion(0,0,0,0) - quaternion.

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

static

Returns a QQuaternion object that is formed by subtracting q2 from q1; each component is subtracted separately.

See also QQuaternion::operator-=().

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

static

Returns the QQuaternion object formed by dividing all components of the given quaternion by the given divisor.

See also QQuaternion::operator/=().

static bool QtGui.QQuaternion.operator== ( QQuaternion  arg1, QQuaternion  arg2  )

static

new QVector3D QtGui.QQuaternion.RotatedVector

(

QVector3D

vector

)

Rotates vector with this quaternion to produce a new vector in 3D space. The following code:

QVector3D result = q.rotatedVector(vector);

is equivalent to the following:

QVector3D result = (q * QQuaternion(0, vector) * q.conjugate()).vector();

new void QtGui.QQuaternion.SetVector	(	double	x,
		double	y,
		double	z
	)

Sets the vector component of this quaternion to vector.

See also vector() and setScalar().

static QQuaternion QtGui.QQuaternion.Slerp ( QQuaternion  q1, QQuaternion  q2, double  t  )

static

Interpolates along the shortest spherical path between the rotational positions q1 and q2. The value t should be between 0 and 1, indicating the spherical distance to travel between q1 and q2.

If t is less than or equal to 0, then q1 will be returned. If t is greater than or equal to 1, then q2 will be returned.

See also nlerp().

new QVector4D QtGui.QQuaternion.ToVector4D

(

)

Returns this quaternion as a 4D vector.
