Constructor & Destructor Documentation

SbVec3b::SbVec3b (void) [inline]The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().

SbVec3b::SbVec3b (const int8_t v[3]) [inline]Constructs an SbVec3b instance with initial values from v.

SbVec3b::SbVec3b (int8_t x, int8_t y, int8_t z) [inline]Constructs an SbVec3b instance with the initial vector endpoint set to <x, y, z>.

SbVec3b::SbVec3b (const SbVec3ub & v) [inline, explicit]Constructs an SbVec3b instance with initial values from the unsigned 8-bit vector v.

SbVec3b::SbVec3b (const SbVec3s & v) [inline, explicit]Constructs an SbVec3b instance with initial values from the short integer precision vector v.

SbVec3b::SbVec3b (const SbVec3i32 & v) [inline, explicit]Constructs an SbVec3b instance with initial values from the 32-bit integer precision vector v.
