[Insight-users] RayCastInterpolateImageFunction Question

[alex Dowson]

Hi

I am doing DRR using RayCastInterpolateImageFunction . Now I want to do forward projection for SART so I need weight coffiecient from RayCastInterpolateImageFunction. I need Ray Length from start and end point as weight coffiecient. 

Does RayCastInterpolateImageFunction has any function to get Ray Length ?
