Constructor & Destructor Documentation

SbVec2i32::SbVec2i32 ( void   )  [inline]

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

SbVec2i32::SbVec2i32 ( const int32_t  v[2]  )  [inline]

Constructs an SbVec2i32 instance with initial values from v.

SbVec2i32::SbVec2i32 ( int32_t  x,
int32_t  y 
) [inline]

Constructs an SbVec2i32 instance with the initial vector endpoint set to <x,y>.

SbVec2i32::SbVec2i32 ( const SbVec2ui32 v  )  [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the unsigned 32-bit integer precision vector v.

SbVec2i32::SbVec2i32 ( const SbVec2s v  )  [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the short integer precision vector v.

SbVec2i32::SbVec2i32 ( const SbVec2b v  )  [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the 8-bit vector v.

SbVec2i32::SbVec2i32 ( const SbVec2f v  )  [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the floating point precision vector v.

SbVec2i32::SbVec2i32 ( const SbVec2d v  )  [inline, explicit]

Constructs an SbVec2i32 instance with initial values from the double floating point precision vector v.
