DESCRIPTION

2D vector class used to store 2D integer vectors and points. This class is used throughout Inventor for arguments and return values.

METHODS

SbVec2s()

Default constructor.

SbVec2s(const short v[2])

SbVec2s(short x, short y)

Constructor given 2 components.

int32_t dot(const SbVec2f &v) const

Returns dot (inner) product of vector and another vector.

const short * getValue() const

void getValue(short &x, short &y) const

Returns vector components.

void negate()

Negates each component of vector in place.

SbVec2s & setValue(const short v[2])

SbVec2s & setValue(short x, short y)

Sets vector components.

short & operator [](int i)

const short & operator [](int i)

Accesses indexed component of vector.

SbVec2s & operator *=(int d)

SbVec2s & operator *=(double d)

SbVec2s & operator /=(int d)

SbVec2s & operator /=(double d)

Component-wise scalar multiplication and division operators.

SbVec2s & operator +=(const SbVec2s &u)

SbVec2s & operator -=(const SbVec2s &u)

Component-wise vector addition and subtraction operators.

SbVec2s operator -() const

Nondestructive unary negation — returns a new vector.

SbVec2s operator *(const SbVec2s &v, int d)

SbVec2s operator *(const SbVec2s &v, double d)

SbVec2s operator *(int d, const SbVec2s &v)

SbVec2s operator *(double d, const SbVec2s &v)

SbVec2s operator /(const SbVec2s &v, int d)

SbVec2s operator /(const SbVec2s &v, double d)

Component-wise binary scalar multiplication and division operators.

SbVec2s operator +(const SbVec2s &v1, const SbVec2s &v2)

SbVec2s operator -(const SbVec2s &v1, const SbVec2s &v2)

Component-wise binary vector addition and subtraction operators.

int operator ==(const SbVec2s &v1, const SbVec2s &v2)

int operator !=(const SbVec2s &v1, const SbVec2s &v2)

Equality comparison operators.
