The SbVec2f class is a 2 dimensional vector with floating point coordinates.This vector class is used...
Definition: SbVec2f.h:49
a vector class for containing two byte integers.
Definition: SbVec2b.h:48
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.
