[Insight-users] Rigid3DPerspectiveTransform

[Bill Lorensen]

Peter,

I the past at GE, we generated DRR's using the ExpNegativeImageFilter
and AccummulateImageFilter. These resulted in parallel projections
along each of the major planes, not Perspective projections. I do
recall that we also successfully generated arbitrary DRR's with
Insight/Examples/DigitallyReconstructedRadiograph1.cxx. I have no
experience with similar code in InsightApplications. Which code were
you using in InsightApplications?
