Constructor & Destructor Documentation

SbVec2us::SbVec2us (void) [inline]

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

SbVec2us::SbVec2us (const unsigned short v[2]) [inline]

Constructs an SbVec2us instance with initial values from v.

SbVec2us::SbVec2us (unsigned short x, unsigned short y) [inline]

Constructs an SbVec2us instance with the initial vector endpoint set to <x,y>.

SbVec2us::SbVec2us (const SbVec2s & v) [inline, explicit]

Constructs an SbVec2us instance with initial values from the short integer precision vector v.

SbVec2us::SbVec2us (const SbVec2ub & v) [inline, explicit]

Constructs an SbVec2us instance with initial values from the unsigned 8-bit vector v.

SbVec2us::SbVec2us (const SbVec2ui32 & v) [inline, explicit]

Constructs an SbVec2us instance with initial values from the unsigned 32-bit integer precision vector v.
