Constructor & Destructor Documentation

SbVec3d::SbVec3d ( void  )
inline

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

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

Constructs an SbVec3d instance with initial values from v.

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

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

SbVec3d::SbVec3d ( const SbVec3f &  v)
inlineexplicit

Constructs an SbVec3d instance from an SbVec3f instance.

SbVec3d::SbVec3d ( const SbVec3b &  v)
inlineexplicit

Constructs an SbVec3d instance from an SbVec3b instance.

2.5

SbVec3d::SbVec3d ( const SbVec3s &  v)
inlineexplicit

Constructs an SbVec3d instance from an SbVec3s instance.

2.5

SbVec3d::SbVec3d ( const SbVec3i32 &  v)
inlineexplicit

Constructs an SbVec3d instance from an SbVec3i32 instance.

2.5

SbVec3d::SbVec3d ( const SbDPPlane &  p0,
const SbDPPlane &  p1,
const SbDPPlane &  p2 
)

Constructs an SbVec3d instance by combining the three given planes. None of the planes should be parallel to any of the other two, otherwise a divide by zero error will occur.

Member Function Documentation

SbVec3d & SbVec3d::setValue ( const double  v[3])
inline

Set new coordinates for the vector from v. Returns reference to self.

See also
getValue().
SbVec3d & SbVec3d::setValue ( double  x,

const SbVec3d &  v0,
const SbVec3d &  v1,
const SbVec3d &  v2 
)

Set this vector to be the average of v0, v1 and v2. The vector components are weighted by the barycentric vector.

See also
getValue().
SbVec3d & SbVec3d::setValue ( const SbVec3f &  v)

Sets this vector to the single precision vector v, converting the vector to a double precision vector.

SbVec3d & SbVec3d::setValue ( const SbVec3b &  v)

Sets this vector to the vector v.

2.5

SbVec3d & SbVec3d::setValue ( const SbVec3s &  v)

Sets this vector to the vector v.

2.5

SbVec3d & SbVec3d::setValue ( const SbVec3i32 &  v)

Sets this vector to the vector v.

2.5

const double * SbVec3d::getValue ( void  ) const
inline

Returns a pointer to an array of three doubles containing the x, y and z coordinates of the vector.

See also
setValue().
void SbVec3d::getValue ( double &  x,

double &  z 
) const
inline

Returns the x, y and z coordinates of the vector.

See also
setValue().
double & SbVec3d::operator[] ( const int  i)
inline

Index operator. Returns modifiable x, y or z coordinate of vector.

See also
getValue() and setValue().
double SbVec3d::operator[] ( const int  i) const
inline

Index operator. Returns x, y or z coordinate of vector.
