◆ midPoint() [1/2]

Vector2 Ogre::VectorBase< 2, Real >::midPoint ( const Vector2 & vec ) const

inline

Returns a vector at a point half way between this and the passed in vector.

◆ randomDeviant() [1/2]

Vector2 Ogre::VectorBase< 2, Real >::randomDeviant ( Radian angle ) const

inline

Generates a new random vector which deviates from this vector by a given angle in a random direction.

Remarks: This method assumes that the random number generator has already been seeded appropriately.

Parameters

angle The angle at which to deviate in radians

Returns: A random vector which deviates from this vector by angle. This vector will not be normalised, normalise it if you wish afterwards.

References Ogre::Math::Cos(), Ogre::Math::RangeRandom(), and Ogre::Math::Sin().

◆ angleTo()

Radian Ogre::VectorBase< 2, Real >::angleTo ( const Vector2 & other ) const

inline

Gets the oriented angle between 2 vectors.

Remarks: Vectors do not have to be unit-length but must represent directions. The angle is comprised between 0 and 2 PI.

References Ogre::Math::TWO_PI.

◆ perpendicular() [1/2]

Vector2 Ogre::VectorBase< 2, Real >::perpendicular ( void ) const

inline

Generates a vector perpendicular to this vector (eg an 'up' vector).

Remarks: This method will return a vector which is perpendicular to this vector. There are an infinite number of possibilities but this method will guarantee to generate one of them. If you need more control you should use the Quaternion class.

◆ perpendicular() [2/2]

Vector3 Ogre::VectorBase< 3, Real >::perpendicular ( void ) const

inline

Generates a vector perpendicular to this vector (eg an 'up' vector).

Remarks: This method will return a vector which is perpendicular to this vector. There are an infinite number of possibilities but this method will guarantee to generate one of them. If you need more control you should use the Quaternion class.

References Ogre::Math::Abs(), and Ogre::Vector< dims, T >::normalisedCopy().

◆ crossProduct()

Vector3 Ogre::VectorBase< 3, Real >::crossProduct ( const Vector3 & rkVector ) const

inline

Calculates the cross-product of 2 vectors, i.e.

the vector that lies perpendicular to them both.

Remarks: The cross-product is normally used to calculate the normal vector of a plane, by calculating the cross-product of 2 non-equivalent vectors which lie on the plane (e.g. 2 edges of a triangle).

Parameters

rkVector Vector which, together with this one, will be used to calculate the cross-product.

Returns

A vector which is the result of the cross-product. This vector will NOT be normalised, to maximise efficiency

call Vector3::normalise on the result if you wish this to be done. As for which side the resultant vector will be on, the returned vector will be on the side from which the arc from 'this' to rkVector is anticlockwise, e.g. UNIT_Y.crossProduct(UNIT_Z) = UNIT_X, whilst UNIT_Z.crossProduct(UNIT_Y) = -UNIT_X. This is because OGRE uses a right-handed coordinate system.

: For a clearer explanation, look a the left and the bottom edges of your monitor's screen. Assume that the first vector is the left edge and the second vector is the bottom edge, both of them starting from the lower-left corner of the screen. The resulting vector is going to be perpendicular to both of them and will go inside the screen, towards the cathode tube (assuming you're using a CRT monitor, of course).

◆ midPoint() [2/2]

Vector3 Ogre::VectorBase< 3, Real >::midPoint ( const Vector3 & vec ) const

inline

Returns a vector at a point half way between this and the passed in vector.

◆ randomDeviant() [2/2]

Vector3 Ogre::VectorBase< 3, Real >::randomDeviant	(	const Radian &	angle,
		const Vector3 &	up = `ZERO`
	)		const

inline

Generates a new random vector which deviates from this vector by a given angle in a random direction.

Remarks: This method assumes that the random number generator has already been seeded appropriately.

Parameters

angle	The angle at which to deviate
up	Any vector perpendicular to this one (which could generated by cross-product of this vector and any other non-colinear vector). If you choose not to provide this the function will derive one on it's own, however if you provide one yourself the function will be faster (this allows you to reuse up vectors if you call this method more than once)

Returns: A random vector which deviates from this vector by angle. This vector will not be normalised, normalise it if you wish afterwards.

References Ogre::Quaternion::FromAngleAxis(), Ogre::Math::TWO_PI, and Ogre::Math::UnitRandom().

◆ getRotationTo()

Quaternion Ogre::VectorBase< 3, Real >::getRotationTo	(	const Vector3 &	dest,
		const Vector3 &	fallbackAxis = `ZERO`
	)		const

inline

Gets the shortest arc quaternion to rotate this vector to the destination vector.

Remarks: If you call this with a dest vector that is close to the inverse of this vector, we will rotate 180 degrees around the 'fallbackAxis' (if specified, or a generated axis if not) since in this case ANY axis of rotation is valid.

References Ogre::Math::Abs(), Ogre::Vector< dims, T >::dotProduct(), Ogre::Quaternion::IDENTITY, Ogre::Quaternion::normalise(), Ogre::Math::RealEqual(), Ogre::Math::Sqrt(), and Ogre::Vector< dims, T >::squaredLength().

◆ positionCloses()

bool Ogre::VectorBase< 3, Real >::positionCloses	(	const Vector3 &	rhs,
		Real	tolerance = `1e-03f`
	)		const

inline

Returns whether this vector is within a positional tolerance of another vector, also take scale of the vectors into account.

Parameters

rhs	The vector to compare with
tolerance	The amount (related to the scale of vectors) that distance of the vector may vary by and still be considered close

References Ogre::Vector< dims, T >::squaredLength().

bool Ogre::VectorBase< 3, Real >::directionEquals	(	const Vector3 &	rhs,
		const Radian &	tolerance
	)		const

inline

Note: Both vectors should be normalised.
