The SbVec4d class is a 4 dimensional vector with double precision floating point coordinates.This vector class is not by many other classes in Coin. It provides storage for a 3 dimensional homogeneoues vector (with the 4 components usually referred to as <x, y, z, w>) aswell as simple double precision floating point arithmetic operations.
