NAME
SbVec2d -SYNOPSIS
#include <Inventor/SbLinear.h>
Detailed Description
The SbVec2d class is a 2 dimensional vector with double precision floating point coordinates.
This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions aswell as simple floating point arithmetic operations on this vector.
