Detailed Description

The SbVec4b class is a 4 dimensional vector with 8-bit 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

◆ SbVec4b() [1/6]

SbVec4b::SbVec4b ( void  )
inline

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

◆ SbVec4b() [2/6]

SbVec4b::SbVec4b ( const int8_t  v[4])
inline

Constructs an SbVec4b instance with initial values from v.

◆ SbVec4b() [3/6]

SbVec4b::SbVec4b ( int8_t  x,
int8_t  y,
int8_t  z,
int8_t  w 
)
inline

Constructs an SbVec4b instance with the initial homogeneous vector set to <x,y,z,w>.

◆ SbVec4b() [4/6]

SbVec4b::SbVec4b ( const SbVec4ub v)
inlineexplicit

Constructs an SbVec4b instance with initial values from the unsigned 8-bit integer precision vector v.

◆ SbVec4b() [5/6]

SbVec4b::SbVec4b ( const SbVec4s v)
inlineexplicit

Constructs an SbVec4b instance with initial values from the short integer precision vector v.

◆ SbVec4b() [6/6]

SbVec4b::SbVec4b ( const SbVec4i32 v)
inlineexplicit

Constructs an SbVec4b instance with initial values from the 32-bit integer precision vector v.

Member Function Documentation

◆ setValue() [1/5]

SbVec4b & SbVec4b::setValue ( const int8_t  v[4])

SbVec4b & SbVec4b::setValue ( int8_t  x,
int8_t  y,
int8_t  z,
int8_t  w 
)
inline

getValue()

◆ setValue() [3/5]

SbVec4b & SbVec4b::setValue ( const SbVec4ub v)

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

◆ setValue() [4/5]

SbVec4b & SbVec4b::setValue ( const SbVec4s v)

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

◆ setValue() [5/5]

SbVec4b & SbVec4b::setValue ( const SbVec4i32 v)

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

◆ getValue() [1/2]

const int8_t * SbVec4b::getValue ( void  ) const
inline

Returns a pointer to an array of four int8_t integers containing the x, y, z and w coordinates of the vector.

void SbVec4b::getValue ( int8_t &  x,
int8_t &  y,
int8_t &  z,
int8_t &  w 
) const
inline

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

◆ operator[]() [1/2]

int8_t & SbVec4b::operator[] ( int  i)
inline

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

◆ operator[]() [2/2]

const int8_t & SbVec4b::operator[] ( int  i) const
inline

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