toFrame()

template<typename T , typename U >

static GloballyPositioned<T> FrameChanger::toFrame ( const GloballyPositioned< T > &  plane, const GloballyPositioned< U > &  frame  )

inlinestatic

Moves the first argument ("plane") to the reference frame given by the second argument ("frame"). The returned frame is not positioned globally!
