Detailed Description

General purpose double triple for use as vertices, vectors and normals. Provides general math operations from addition through to cross products. No support yet added for double * Vec3d - is it necessary? Need to define a non-member non-friend operator* etc. Vec3d * double is okay

Member Function Documentation

bool osg::Vec3d::isNaN (   )  const [inline]

value_type osg::Vec3d::length (   )  const [inline]

Length of the vector = sqrt( vec . vec )

value_type osg::Vec3d::length2 (   )  const [inline]

Length squared of the vector = vec . vec

value_type osg::Vec3d::normalize (   )  [inline]

Normalize the vector so that it has length unity. Returns the previous length of the vector.

const Vec3d osg::Vec3d::operator * (  value_type  rhs  )  const [inline]

Multiply by scalar.

value_type osg::Vec3d::operator * (  const Vec3d &  rhs  )  const [inline]

Dot product.

Vec3d& osg::Vec3d::operator *= (  value_type  rhs  )  [inline]

Unary multiply by scalar.

osg::Vec3d::operator Vec3f (   )  const [inline]

bool osg::Vec3d::operator!= (  const Vec3d &  v  )  const [inline]

const Vec3d osg::Vec3d::operator+ (  const Vec3d &  rhs  )  const [inline]

Binary vector add.

Vec3d& osg::Vec3d::operator+= (  const Vec3d &  rhs  )  [inline]

Unary vector add. Slightly more efficient because no temporary intermediate object.

const Vec3d osg::Vec3d::operator- (   )  const [inline]

Negation operator. Returns the negative of the Vec3d.

const Vec3d osg::Vec3d::operator- (  const Vec3d &  rhs  )  const [inline]

Binary vector subtract.

Vec3d& osg::Vec3d::operator-= (  const Vec3d &  rhs  )  [inline]

Unary vector subtract.

const Vec3d osg::Vec3d::operator/ (  value_type  rhs  )  const [inline]

Divide by scalar.

Vec3d& osg::Vec3d::operator/= (  value_type  rhs  )  [inline]

Unary divide by scalar.

bool osg::Vec3d::operator< (  const Vec3d &  v  )  const [inline]

bool osg::Vec3d::operator== (  const Vec3d &  v  )  const [inline]
