// .NAME vtkFrustumSource - create a polygonal representation of a frustum
// .SECTION Description
// vtkFrustumSource creates a frustum defines by a set of planes. The frustum
// is represented with four-sided polygons. It is possible to specify extra
// lines to better visualize the field of view.
//
// .SECTION Usage
// Typical use consists of 3 steps:
// 1. get the planes coefficients from a vtkCamera with
// vtkCamera::GetFrustumPlanes()
// 2. initialize the planes with vtkPlanes::SetFrustumPlanes() with the planes
// coefficients
// 3. pass the vtkPlanes to a vtkFrustumSource.
