Interactive Raytracing: The nirt Command

Report No. ARL-CR-624
Authors: Clifford Yapp
Date/Pages: April 2009; 58 pages
Abstract: The nirt command casts individual rays according to user-specified options and reports back a wide variety of information about the model along the specified ray. It is extremely useful for tasks such as measuring the thickness of objects and identifying gaps between objects. When used within the multidevice graphics editor environment, NIRT will produce a visible ray path, coloring the ray according to the geometry encountered along the ray. It is also scriptable, allowing users to develop their own custom analysis routines.
