Interactive Raytracing: The nirt Command

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 multi-device 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.
