Detailed Description

template<unsigned int VDimension = 3>
class itk::SpatialObject< VDimension >

Implementation of the composite pattern.

The purpose of this class is to implement the composite pattern [Design Patterns, Gamma, 1995] within itk, so that it becomes easy to create an environment containing objects within a scene, and to manipulate the environment as a whole or any of its component objects. An object has a list of transformations to transform index coordinates to the corresponding coordinates in the real world coordinate system, and a list of inverse transformation to go backward. Any spatial objects can be plugged to a spatial object as children. To implement your own spatial object, you need to derive from the following class, which requires the definition of just a few pure virtual functions. Examples of such functions are ValueAt(), IsEvaluableAt(), and IsInside(), each of which has a meaning specific to each particular object type.
