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.
