+<span class="text">This module provides a set of classes that manage the
+visualization and the interaction with images. For example, the black box
+ViewerNV is constructed using these classes and it provides the possibility to
+use different viewers depending of the context. For example, to manage an image
+3D is useful to use the wxVtk3DBaseBiew and to control a 2D image it is possible
+to use wxVtk2DBaseView. It is important to note that these viewers make the
+connection between a wxWindow and a vtkRenderWindow, in order to include the
+world VTK in any application implemented with wxWidgets.<br />
+<br />
+Another important point to keep in mind is that all the wxVtkBaseView instances
+have a manager of its interactor styles. These interactors describe how the
+events are handled and how the actual mechanism respond to the interaction
+callbacks. Every new instance of InteractorStyleMaracas class can be added to
+the wxBaseView in order to manage all the events made over an object. An example
+of this process is presented in the contours section.</span><br />
