Constructor & Destructor Documentation

◆ SbVec2b() [1/6]

SbVec2b::SbVec2b ( void  )
inline

The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().

◆ SbVec2b() [2/6]

SbVec2b::SbVec2b ( const int8_t  v[2])
inline

Constructs an SbVec2b instance with initial values from v.

◆ SbVec2b() [3/6]

SbVec2b::SbVec2b ( int8_t  x,
int8_t  y 
)
inline

Constructs an SbVec2b instance with the initial vector endpoint set to <x,y>.

◆ SbVec2b() [4/6]

SbVec2b::SbVec2b ( const SbVec2ub v)
inlineexplicit

Constructs an SbVec2b instance with initial values from the unsigned 8-bit vector v.

◆ SbVec2b() [5/6]

SbVec2b::SbVec2b ( const SbVec2s v)
inlineexplicit

Constructs an SbVec2b instance with initial values from the short integer precision vector v.

◆ SbVec2b() [6/6]

SbVec2b::SbVec2b ( const SbVec2i32 v)
inlineexplicit

Constructs an SbVec2b instance with initial values from the 32-bit integer precision vector v.

Member Function Documentation

◆ setValue() [1/5]

SbVec2b & SbVec2b::setValue ( const int8_t  v[2])
inline

Set new coordinates for the vector from v. Returns reference to self.

See also
getValue()

◆ setValue() [2/5]

SbVec2b & SbVec2b::setValue ( int8_t  x,
int8_t  y 
)
inline

Set new coordinates for the vector. Returns reference to self.

See also
getValue()

◆ setValue() [3/5]

SbVec2b & SbVec2b::setValue ( const SbVec2ub v)

Sets this vector to the unsigned 8-bit integer precision vector v, converting the vector to an 8-bit integer precision vector

◆ setValue() [4/5]

SbVec2b & SbVec2b::setValue ( const SbVec2s v)

Sets this vector to the short integer precision vector v, converting the vector to an 8-bit integer precision vector.

◆ setValue() [5/5]

SbVec2b & SbVec2b::setValue ( const SbVec2i32 v)

Sets this vector to the 32-bit integer precision vector v, converting the vector to an 8-bit integer precision vector.

◆ getValue() [1/2]

const int8_t * SbVec2b::getValue ( void  ) const
inline

Returns a pointer to an array of two 8-bit integers containing the x and y coordinates of the vector.

See also
setValue()

◆ getValue() [2/2]

void SbVec2b::getValue ( int8_t &  x,
int8_t &  y 
) const
inline

Returns the x and y coordinates of the vector.

See also
setValue()

◆ operator[]() [1/2]

int8_t & SbVec2b::operator[] ( int  i)
inline

Index operator. Returns modifiable x or y coordinate of the vector.

See also
getValue() and setValue()

◆ operator[]() [2/2]

const int8_t & SbVec2b::operator[] ( int  i) const
inline

Index operator. Returns non-modifiable x or y coordinate of the vector.

See also
getValue() and setValue()

◆ dot()

int32_t SbVec2b::dot ( SbVec2b  v) const
inline

Calculates and returns the result of taking the dot product of this vector and v.

◆ negate()

inline

Negate the vector (i.e. point it in the opposite direction)

◆ operator*=() [1/2]

SbVec2b & SbVec2b::operator*= ( int  d)
inline

Multiply components of vector with scalar value d. Returns reference to self.

◆ operator*=() [2/2]

SbVec2b & SbVec2b::operator*= ( double  d)

◆ operator/=() [2/2]

SbVec2b & SbVec2b::operator/= ( double  d)
inline

Divides components of vector with double precision floating point value d. Returns reference to self.

◆ operator+=()

SbVec2b & SbVec2b::operator+= ( SbVec2b  v)
inline

Adds this vector and vector u. Returns reference to self.

◆ operator-=()

inline

Subtracts vector u from this vector. Returns reference to self.

◆ operator-()

SbVec2b SbVec2b::operator- ( void  ) const
inline

Non-destructive negation operator. Returns a new SbVec2b instance which points in the opposite direction of this vector.
