Detailed Description

template<class T>
class tagGame::Vec< T >

A basic templatized vector class.

The world probably doesn't need yet another vector class, but this one has several desirable properties:

• it uses the same code style as the rest of the game source;
• it is templatized to support integer and floating-point vectors;
• it is simple and light-weight;
• it avoids any "behind the scenes" copying of objects;
• it avoids almost all use of operator overloading (can make code hard to read)
• it allows arbiray length vectors (partial template specializations could be written to provide faster special case implmentations for 2D, 3D and 4D vectors).
• it makes extensive use of STL to simplify and reduce the amount of code (STL could be expanded and improved to make the code even simpler and shorter).

It is not however meant to be a fully fledged linear algebra class. If you are looking for such a library try www.boost.org, geometrictools.com, or any of a host of other libraries.
