Constructor & Destructor Documentation

SbVec3d::SbVec3d (void) [inline]

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

Referenced by cross(), and operator-().

SbVec3d::SbVec3d (const double v[3])

Constructs an SbVec3d instance with initial values from v.

SbVec3d::SbVec3d (const double x, const double y, const double z)

Constructs an SbVec3d instance with the initial vector endpoint set to <x,y,z>.

SbVec3d::SbVec3d (const SbVec3f & v)

Constructs an SbVec3d instance with initial values from the single precision vector v.

DEPRECATED for Coin 3.0 -- don't use this.
