3D vector class.
3D vector class used to store 3D vectors and points. This class is used throughout Open Inventor for arguments and return values.
Notes:
- All methods that return a vector value, e.g. operator-, are creating a new SbVec3f object on every call. This is convenient but developers should keep in mind that it is also time consuming if used, for example, in a loop that calls the method many times. The methods, for example, operator-= that modify one of the objects are much more efficient when elapsed time is important.
