Detailed Description

template<class T>
class vgl_vector_3d< T >

Direction vector in Euclidean 3D space, templated by type of element.

(typically float or double). A vgl_vector_3d<T> represents the difference (or connecting vector) between two vgl_point_3d<T>s.

Use this class to do arithmetic (adding and scaling) in 3d geometric space.
