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

Constructs an SbVec4d instance with initial values from v.

Constructs an SbVec4d instance with the initial homogeneous vector set to <x,y,z,w>.

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

setValue().

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

setValue().

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

getValue() and setValue().

Index operator. Returns x, y, z or w component of vector.

getValue() and setValue().

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

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

The comparison is done in 4D-space, i.e. the w component of the vector is not used to make x, y and z into Cartesian coordinates first.

Returns the vector as a Cartesian 3D vector in v. This means that the 3 first components x, y and z will be divided by the fourth, w.

Return the length of the vector in 4D space.

Return the square of the length of the vector in 4D space.

Negate the vector.

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

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

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

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

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

Non-destructive negation operator. Returns a new SbVec4d instance which has all components negated.

See also

negate().

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

Returns an SbVec4d instance which is the components of vector v multiplied with d.

Returns an SbVec4d instance which is the components of vector v multiplied with d.

Returns an SbVec4d instance which is the components of vector v divided on the scalar factor d.

Returns an SbVec4d instance which is the sum of vectors v1 and v2.

Returns an SbVec4d instance which is vector v2 subtracted from vector v1.

Returns 1 if v1 and v2 are equal, 0 otherwise.

See also

equals().

Returns 1 if v1 and v2 are not equal, 0 if they are equal.
