Detailed Description

template<unsigned int VDimension>
class itk::ParametricPath< VDimension >

Represent a parametric path through ND Space.

This virtual class is intended to represent a parametric path through an image. A parametric path maps a single floating-point 1D parameter (usually designated as either time or arc-length) to a floating-point ND point in continuous image index space. This mapping is done via the abstract Evaluate() method, which must be overridden in all instantiable subclasses. Parametric paths are required to be continuous. They may be open or form a closed loop. A parametric path may cross itself several times, although the end point is constrained to have a unique spatial location unless it is shared with and only with the starting point (a path tracing the number "9," starting at the bottom and ending in the middle of the right side, would therefore be illegal). Classic applications of this class include the representation of contours in 2D images and path smoothing. Another use of a path is to guide the movement of an iterator through an image.
