SbVec3f — 3D vector class

       3D vector class used to store 3D vectors and points. This class is used throughout Inventor for arguments
       and return values.

       SbVec3f

SbVec3f()
          Default constructor.

                         SbVec3f(constfloatv[3])SbVec3f(floatx,floaty,floatz)
          Constructor given vector components.

                         SbVec3f(SbPlane&p0,SbPlane&p1,SbPlane&p2)
          Constructor given 3 planes.

     SbVec3fcross(constSbVec3f&v)const
          Returns right-handed cross product of vector and another vector.

     floatdot(constSbVec3f&v)const
          Returns dot (inner) product of vector and another vector.

     SbBoolequals(constSbVec3fv,floattolerance)const
          Equality  comparison within given tolerance — the square of the length of the maximum distance between
          the two vectors.

     SbVec3fgetClosestAxis()const
          Returns principal axis that is closest (based on maximum dot product) to this vector.

     constfloat*getValue()constvoidgetValue(float&x,float&y,float&z)const
          Returns vector components.

     floatlength()const
          Returns geometric length of vector.

     voidnegate()
          Negates each component of vector in place.

     floatnormalize()
          Changes vector to be unit length, returning the length before normalization.

     SbVec3f&setValue(constfloatv[3])SbVec3f&setValue(floatx,floaty,floatz)
          Sets the vector components.

     SbVec3f&setValue(constSbVec3f&barycentic,constSbVec3f&v0,constSbVec3f&v1,constSbVec3f&v2)
          Sets value of vector as the weighted average of 3 other vectors.

     float&operator[](inti)constfloat&operator[](inti)
          Accesses indexed component of vector.

     SbVec3f&operator*=(floatd)SbVec3f&operator/=(floatd)
          Component-wise scalar multiplication and division operators.

     SbVec3f&operator+=(constSbVec3f&u)SbVec3f&operator-=(constSbVec3f&u)
          Component-wise vector addition and subtraction operators.

     SbVec3foperator-()const
          Nondestructive unary negation — returns a new vector.

     SbVec3foperator*(constSbVec3f&v,floatd)SbVec3foperator*(floatd,constSbVec3f&v)SbVec3foperator/(constSbVec3f&v,floatd)
          Component-wise binary scalar multiplication and division operators.

     SbVec3foperator+(constSbVec3f&v1,constSbVec3f&v2)SbVec3foperator-(constSbVec3f&v1,constSbVec3f&v2)
          Component-wise binary vector addition and subtraction operators.

     intoperator==(constSbVec3f&v1,constSbVec3f&v2)intoperator!=(constSbVec3f&v1,constSbVec3f&v2)
          Equality comparison operators.
