[vtkusers] Ray Casters and Perspective View Rays

[Turner, Wesley D (CRD)]

Lisa,

In some of the code I use, there are several modules which use the obsolete "vtkRayCaster" and
"vtkViewRays".  In particular, I use a routine which calculates
range and angle of incidence data based on the sequence of calls
vtkOpenGLRendererInstance->GetRayCaster()->GetPerspectiveViewRays().  You removed these
modules from the VTK repository and seem to have moved their functionality into other places.  Is
there a set of replacement calls?  Can these modules be moved 
back into the repository?

Thank you in advance for your help,

- Wes Turner
