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.
Definition: SbVec4d.h:49
The SbDPMatrix class is a 4x4 dimensional representation of a double-precision matrix.This class is like the SbMatrix class, but uses double-precision floating point values for its elements. For more class documentation, see SbMatrix.
