The WorldToolKit Neutral File Format is a creation of Sense8 for their
WorldToolKit software product. WorldToolKit is a C language library providing
the functionality needed to do virtual reality, including file parsing,
sensor drivers, object management, behavior, and rendering.

Sense8's NFF format was loosely adapted from the Videoscape (.geo) format,
with the addition of 12-bit color, per-polygon texture application, and
portals. It was later extended to support vertex normals, 24-bit color, and
vertex uv coordinates. The current version of NFF is 2.1.

Sense8 also supports a binary format of NFF called BFF (.bff file extension)
The BFF format layout and order is identical to the ASCII version, with the
exception that only 24-bit, and not 12-bit, colors are not supported.

The WorldToolKit Neutral File Format was created and is maintained by:
