Constructor & Destructor Documentation

SbVec2b::SbVec2b (void) [inline]

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

SbVec2b::SbVec2b (const int8_t v[2]) [inline]

Constructs an SbVec2b instance with initial values from v.

SbVec2b::SbVec2b (int8_t x, int8_t y) [inline]

Constructs an SbVec2b instance with the initial vector endpoint set to <x,y>.

SbVec2b::SbVec2b (const SbVec2ub & v) [inline, explicit]

Constructs an SbVec2b instance with initial values from the unsigned 8-bit vector v.

SbVec2b::SbVec2b (const SbVec2s & v) [inline, explicit]

Constructs an SbVec2b instance with initial values from the short integer precision vector v.

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

Constructs an SbVec2b instance with initial values from the 32-bit integer precision vector v.

Member Function Documentation
