// In this example we show how to use a GroupSpatialObject.
//
// Let's begin by including the appropriate header file.

// Software Guide : EndLatex
// Software Guide : BeginCodeSnippet
typedef itk::GroupSpatialObject<3> GroupType;

// Software Guide : EndCodeSnippet
// Software Guide : BeginLatex

myEllipse->SetRadius(2);

// Software Guide : EndCodeSnippet
// Software Guide : BeginLatex
// We then translate the group by 10mm in each direction.
// Therefore the ellipse is translated in physical space at the same time.

// Software Guide : BeginCodeSnippet

// Software Guide : BeginLatex
// We can then query if a point is inside the group using the
// \code{IsInside()} function. We need to specify in this case that
// we want to consider all the hierarchy, therefore we set the depth to 2.
// Software Guide : EndLatex
// Software Guide : BeginCodeSnippet
