Detailed Description

template<typename TDomain3D, typename TInteger = DGtal::Z3i::Integer>
class DGtal::functors::SliceRotator2D< TDomain3D, TInteger >

Special Point Functor that adds one dimension to a 2D point and apply on it a rotation of angle alpha according to a given direction and the domain center. It also checks if the resulting point is inside the 3D domain, else it returns a particular point (by default the point at domain origin (from the domain method lowerBound()).

Description of template class 'SliceRotator2D'

Ex: a Point P (10, 9) in the domain (defined (0,0,0) (10,10,10)) given in 3D by adding the dimension in Z (2) with slice num 7: => P(10, 9, 7) and after a rotation of PI from center of slice domain (5,5, 7) will give P(0,1,7). To apply this example you can test it with:

// Defining the domain
PointVector<3, int> pt1(0,0, 0);
PointVector<3, int> pt2(10,10, 10);
HyperRectDomain<SpaceND<3, int> >  domain (pt1, pt2);
// The functor on axis rotation set to 2 with new Z slice num=7 and angle 3.15:
SliceRotator2D< HyperRectDomain<SpaceND<3, int> >, int> sliceRot2(2, domain, 7, 2, 3.14);
PointVector<2, int> pt_2(10, 9);
trace.info() <<  sliceRot2(pt_2);

Template Parameters

TDomain3D	the type of the 3d domain.
TInteger	specifies the integer number type used to define the space.
