getAASquareVertices()

template<typename T>

std::array< T, 4 > DGtal::drawutils::getAASquareVertices	(	T	center,
		int	orientation,
		double	size )

orientation	The orientation of the cell (x, y, z)
size1	Size of the first square
size2	Size of the second square
shift1	Shift (relative to center) of the first square
shift2	Shift (relative to center) of the second square

template<typename U, typename T>

void DGtal::drawutils::insertAASquare	(	U &	dest,
		T	center,
		int	orientation,
		double	size )

Insert vertices of a square into a container.

Template Parameters

U	The container
T	The type of vertex

Parameters

dest	The container where the vertices shoudl be inserted
center	The center of the square
orientation	0 means normal in x direction, 1 in y-direction, 2 in z-direction
size	The size of the square
