Ok, I have an object of one class, and I want to pass it to a function which is set to take an object of another class. What would be the best way of going about this? Hopefully an example will make some sense out of my question. Say I'm using two libraries, a physics library and a graphics library. Each of these has their own 3D vector class. I have an object which needs to send data to both these libraries.

//physics library
void Physics::MoveObject( physVector pos )
{};

//graphics library
void Graphics::RenderObject( graphicsVector pos )
{};

//my code
class Entity
{
     MyVector pos;
};

void Update()
{
   Entity ent;

   Physics::MoveObject( ent.pos );
   Graphics::RenderObject( ent.pos );
}

Is there a way to do this? By writing some method in MyVector that will convert itself to either a graphicsVector or a physVector? Or do I end up with,

Physics::MoveObject( ent.pos.ToPhysVector );
Graphics::RenderObject( ent.pos.ToGraphicsVector );

And if that's the case, what's the best way of doing that? Cheers, Zenix.
