Detailed Description

The SbVec4s class is a 4 dimensional vector with short integer coordinates.

This vector class provides storage for a 3 dimensional homogeneoues vector (with the 4 components usually referred to as <x, y, z, w>) aswell as simple integer precision arithmetic operations.

Constructor & Destructor Documentation

SbVec4s::SbVec4s ( void  ) [inline]

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

SbVec4s::SbVec4s ( const short  v[4]) [inline]

Constructs an SbVec4s instance with initial values from v.

SbVec4s::SbVec4s ( short  x,
short  y,
short  z,
short  w 
) [inline]

Constructs an SbVec4s instance with the initial homogeneous vector set to <x,y,z,w>.

SbVec4s::SbVec4s ( const SbVec4us v) [inline, explicit]

Constructs an SbVec4s instance with initial values from the unsigned short integer precision vector v.

SbVec4s::SbVec4s ( const SbVec4b v) [inline, explicit]

Constructs an SbVec4s instance with initial values from the 8-bit integer precision vector v.

SbVec4s::SbVec4s ( const SbVec4i32 v) [inline, explicit]

Constructs an SbVec4s instance with initial values from the 32-bit integer precision vector v.


Member Function Documentation

SbVec4s & SbVec4s::setValue ( const short  v[4]) [inline]

See also:
getValue()
SbVec4s & SbVec4s::setValue ( short  x,
short  y,
short  z,
short  w 
) [inline]

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

getValue()
SbVec4s & SbVec4s::setValue ( const SbVec4s v) [inline]

Constructs an SbVec4s instance with initial values from the vector v.

SbVec4s & SbVec4s::setValue ( const SbVec4us v)

Sets this vector to the unsigned short integer precision vector v, converting the vector to a short integer precision vector.

SbVec4s & SbVec4s::setValue ( const SbVec4b v)

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

SbVec4s & SbVec4s::setValue ( const SbVec4i32 v)

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

const short * SbVec4s::getValue ( void  ) const [inline]

Returns a pointer to an array of four short integers containing the x, y, z and w coordinates of the vector.

See also:
setValue()
void SbVec4s::getValue ( short &  x,
short &  y,
short &  z,
short &  w 
) const [inline]

Returns the x, y, z and w coordinates of the vector.

short & SbVec4s::operator[] ( int  i) [inline]

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

const short & SbVec4s::operator[] ( int  i) const [inline]

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

int32_t SbVec4s::dot ( const SbVec4s v) const [inline]

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

void SbVec4s::negate ( void  ) [inline]

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

SbVec4s & SbVec4s::operator*= ( int  d) [inline]

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

SbVec4s & SbVec4s::operator*= ( double  d)

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

SbVec4s & SbVec4s::operator/= ( int  d) [inline]

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

SbVec4s & SbVec4s::operator/= ( double  d) [inline]

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

SbVec4s & SbVec4s::operator+= ( const SbVec4s v) [inline]

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