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) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3f instance.

SbVec3d::SbVec3d (const SbVec3b & v) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3b instance.

2.5

SbVec3d::SbVec3d (const SbVec3s & v) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3s instance.

2.5

SbVec3d::SbVec3d (const SbVec3i32 & v) [inline], [explicit]

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, double y, double z) [inline]

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

See also:

getValue().

SbVec3d & SbVec3d::setValue (const SbVec3d & barycentric, 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 & y, 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.

See also:

getValue() and setValue().

SbVec3d SbVec3d::cross (const SbVec3d & v) const

Returns the result of taking the cross product of this vector and v.

double SbVec3d::dot (const SbVec3d & v) const [inline]

Calculates and returns the result of taking the dot product of this vector and v.

SbBool SbVec3d::equals (const SbVec3d & v, double tolerance) const

Compares the vector with v and returns TRUE if the distance between the vectors is smaller or equal to the square root of tolerance.

SbVec3d SbVec3d::getClosestAxis (void) const

Return the vector representing the principal axis closest to this vector.

double SbVec3d::length (void) const

Return length of vector.

double SbVec3d::sqrLength (void) const [inline]

void SbVec3d::negate (void) [inline]

Negate the vector (i.e. point it in the opposite direction).

double SbVec3d::normalize (void)

Normalize the vector to unit length. Return value is the original length of the vector before normalization.

If the vector is the null vector, no attempt at normalization will be done.

SbVec3d & SbVec3d::operator*= (double d) [inline]

Multiply components of vector with value d. Returns reference to self.

SbVec3d & SbVec3d::operator/= (double d) [inline]

Divides components of vector with value d. Returns reference to self.

Adds this vector and vector v. Returns reference to self.

SbVec3d & SbVec3d::operator-= (const SbVec3d & v) [inline]

Subtracts vector v from this vector. Returns reference to self.

SbVec3d SbVec3d::operator- (void) const [inline]

Non-destructive negation operator. Returns a new SbVec3d instance which points in the opposite direction of this vector.

See also:

negate().

void SbVec3d::print (FILE * fp) const

Dump the state of this object to the file stream. Only works in debug version of library, method does nothing in an optimized compile.
