[vtkusers] Ray Casters and Perspective View Rays

[Turner, Wesley D (CRD)]

Lisa,

Sorry for not responding sooner, but I have been off for the holidays.
We are calculating a synthetic range image (possibly having noise) from
the rendered image.  The ViewRays class provided a convenient API for
quickly obtaining a matrix of data that could be used in various points
in the generation of the range data.  While it is certainly the case that 
I can generate the same data as that returned by the ViewRays object, having
the class simplified the code.  I do not need the data to be automatically
generated by the Renderer, I appear to only need access to the ViewRays 
API.  Can we add it back into the VTK repository?

Thanks,

- Wes

Hello Wes,

You should be able to directly compute anything you were accessing from the 
view rays object. What specifically are you trying to determine? (I am not 
sure what you mean by "range and angle of incidence data")
