Detailed description

[const] bool !=(const QQuaternion q1)

Description: Operator bool ::operator!=(const QQuaternion &q1, const QQuaternion &q2)

This is the mapping of the global operator to the instance method.

[const] QQuaternion *(const QQuaternion q1)

Description: Operator const QQuaternion ::operator*(const QQuaternion &q1, const QQuaternion &q2)

This is the mapping of the global operator to the instance method.

[const] QQuaternion *(double quaternion)

Description: Operator const QQuaternion ::operator*(const QQuaternion &quaternion, double factor)

This is the mapping of the global operator to the instance method.

QQuaternion *=(double factor)

Description: Method QQuaternion & QQuaternion::operator*=(double factor)

QQuaternion *=(const QQuaternion quaternion)

Description: Method QQuaternion & QQuaternion::operator*=(const QQuaternion &quaternion)

[const] QQuaternion +(const QQuaternion q1)

Description: Operator const QQuaternion ::operator+(const QQuaternion &q1, const QQuaternion &q2)

This is the mapping of the global operator to the instance method.

QQuaternion +=(const QQuaternion quaternion)

Description: Method QQuaternion & QQuaternion::operator+=(const QQuaternion &quaternion)

[const] QQuaternion -(const QQuaternion q1)

Description: Operator const QQuaternion ::operator-(const QQuaternion &q1, const QQuaternion &q2)

This is the mapping of the global operator to the instance method.

[const] QQuaternion -(quaternion)

Description: Operator const QQuaternion ::operator-(const QQuaternion &quaternion)

This is the mapping of the global operator to the instance method.

QQuaternion -=(const QQuaternion quaternion)

Description: Method QQuaternion & QQuaternion::operator-=(const QQuaternion &quaternion)

[const] QQuaternion /(double quaternion)

Description: Operator const QQuaternion ::operator/(const QQuaternion &quaternion, double divisor)

This is the mapping of the global operator to the instance method.

QQuaternion /=(double divisor)

Description: Method QQuaternion & QQuaternion::operator/=(double divisor)

[const] bool ==(const QQuaternion q1)

Description: Operator bool ::operator==(const QQuaternion &q1, const QQuaternion &q2)

This is the mapping of the global operator to the instance method.

[const] void assign(const QQuaternion other)

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

[const] QQuaternion conjugate

Description: Method QQuaternion QQuaternion::conjugate()

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

[const] QQuaternion dup

Description: Creates a copy of self

[static] QQuaternion fromAxisAndAngle(const QVector3D axis,double angle)

Description: Static method QQuaternion QQuaternion::fromAxisAndAngle(const QVector3D &axis, double angle)

This method is static and can be called without an instance.

[static] QQuaternion fromAxisAndAngle(double x,double y,double z,double angle)

Description: Static method QQuaternion QQuaternion::fromAxisAndAngle(double x, double y, double z, double angle)

This method is static and can be called without an instance.

[const] bool isIdentity

Description: Method bool QQuaternion::isIdentity()

[const] bool isIdentity?

Description: Method bool QQuaternion::isIdentity()

[const] bool isNull

Description: Method bool QQuaternion::isNull()

[const] bool isNull?

Description: Method bool QQuaternion::isNull()

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

[const] double length

Description: Method double QQuaternion::length()

[const] double lengthSquared

Description: Method double QQuaternion::lengthSquared()

[static] new QQuaternion new

Description: Constructor QQuaternion::QQuaternion()

This method creates an object of class QQuaternion.

[static] new QQuaternion new(const QVector4D vector)

Description: Constructor QQuaternion::QQuaternion(const QVector4D &vector)

This method creates an object of class QQuaternion.

[static] new QQuaternion new(double scalar,const QVector3D vector)

Description: Constructor QQuaternion::QQuaternion(double scalar, const QVector3D &vector)

This method creates an object of class QQuaternion.

[static] new QQuaternion new(double scalar,double xpos,double ypos,double zpos)

Description: Constructor QQuaternion::QQuaternion(double scalar, double xpos, double ypos, double zpos)

This method creates an object of class QQuaternion.

[static] QQuaternion nlerp(const QQuaternion q1,const QQuaternion q2,double t)

Description: Static method QQuaternion QQuaternion::nlerp(const QQuaternion &q1, const QQuaternion &q2, double t)
