This call will load an .nff (Neutral File Format). The result is a valid thinglist suitable for display via the :DRAW <CAMERA> command. NFF is intended as a standard interchange format for 3D objects. Unfortunately, there appear to be as many such standards as there are people desiring one. Support for DEC's .off file format is also contemplated ...
XNFF-LOAD-NFF-FILE is currently useful, but still very incomplete. Files containing only triangulated surfaces should load ok, the sphere and cylinder primitives are not supported yet.
