Detailed Description

The Vector3 class represents the generic vector containing 3 elements.

Since it's commonly used to keep coordinate system related information, its elements are labeled by x, y, z.

Constructor & Destructor Documentation

sdf::Vector3::Vector3 ( const Vector3 &  _v )

inline

Copy constructor.

Parameters

[in]

_v

a vector

Referenced by operator*(), and operator+().

sdf::Vector3::Vector3 ( double  _x = 0.0, double  _y = 0.0, double  _z = 0.0  )

inline

Constructor.

Parameters

[in]	_x	value along x
[in]	_y	value along y
[in]	_z	value along z

Member Function Documentation

Vector3 sdf::Vector3::Cross ( const Vector3 &  _pt ) const

inline

Return the cross product of this vector and pt.

Returns

the product

References x, y, and z.

Referenced by sdf::Quaternion::operator*().

Vector3 sdf::Vector3::operator* ( double  _v ) const

inline

Multiplication operator.

Remarks

this is an element wise multiplication, not a cross product

Parameters

[in]

_v

References Vector3(), x, y, and z.

const Vector3& sdf::Vector3::operator*= ( double  _v )

inline

Multiplication by a double.

Parameters

[in]

_v

A double

Returns

this

References x, y, and z.

Vector3 sdf::Vector3::operator+ ( const Vector3 &  _v ) const

inline

Addition operator.

Parameters

[in]

_v

vector to add

Returns

the sum vector

References Vector3(), x, y, and z.

bool sdf::Vector3::operator== ( const sdf::Vector3 &  _pt ) const

inline

Equal to operator.

Parameters

[in]

_pt

The vector to compare against

Returns

true if each component is equal within a tolerence (1e-3), false otherwise
