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().

Referenced by dot(), operator*=(), operator+=(), operator-(), operator-=(), operator/=(), operator/=(), setValue(), and 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.
