Detailed Description

template<typename TSpace, typename TInputPoint, typename TInternalScalar>
struct DGtal::ChordGenericStandardPlaneComputer< TSpace, TInputPoint, TInternalScalar >::Transform

This type is used to cast points from \((x,y,z)\) to \((x \pm z,y \pm z,z)\) and inversely. This is used when recognize a standard plane. Indeed, we only know how to recognize naive planes. So we dilate points of standard planes with this transform so that the standard plane becomes naive. Otherwise said, if \(T_{\pm,\pm}: (x,y,z) \mapsto (x \pm z,y \pm z,z)\), then P is a standard plane iff one of \(T_{+,+}(P), T_{+,-}(P), T_{-,+}(P), T_{-,-}(P)\) is a naive plane of main axis z.
