Detailed Description

template<class T>
class lti::boxSide< T >

Policy class to compute the size of a box's side and the inverse transformation.

For integer types it assumes the box lies on a discrete grid with grid elements of size 1x1x1, which means that the size of a side defined by two scalar values x1 and x2 (x2>x1) is x2-x1+1.

For floating point values the size is just x2-x1, because of the assumtion that the box lies on a real valued 2D space.

Member Function Documentation

template<class T >

static void lti::boxSide< T >::invSize	(	const T	sz,
		T &	x1,
		T &	x2
	)			[inline, static]

For a given side size, compute two coordinates which generates it.

For example:

• if T is int and sz is 3, the returned values would be x1=-1 and x2=1.
• if T is float and sz = 3, the returned values would be x1=-1.5 and x2=1.5

template<class T >

static T lti::boxSide< T >::size	(	const T	x1,
		const T	x2
	)			[inline, static]

return the size of a box's side which is aligned with one of the two coordinates, assuming that the delimiting coordinates are x1 and x2.

For example:

• if T is int, x1=0 and x2=2, then size returns 3
• if T is float, x1=0 and x2=2 then size returns 2
