15     Since Eric Haines wrote such excellent documentation of his
16     Neutral File Format, I am just going to reprint it here with
17     my added comments in braces {}.

19     Neutral File Format (NFF), by Eric Haines
20    
21     Draft document #1, 10/3/88
22    
23     The NFF (Neutral File Format) is designed as a minimal scene description
24     language. The language was designed in order to test various rendering
25     algorithms and efficiency schemes. It is meant to describe the geometry and
26     basic surface characteristics of objects, the placement of lights, and the
27     viewing frustum for the eye. Some additional information is provided for
28     esthetic reasons (such as the color of the objects, which is not strictly
29     necessary for testing rendering algorithms).
30    
31     Future enhancements include: circle and torus objects, spline surfaces
32     with trimming curves, directional lights, characteristics for positional
33     lights, CSG descriptions, and probably more by the time you read this.
34     Comments, suggestions, and criticisms are all welcome.
35    
36     At present the NFF file format is used in conjunction with the SPD (Standard
37     Procedural Database) software, a package designed to create a variety of
38     databases for testing rendering schemes. The SPD package is available
39     from Netlib and via ftp from drizzle.cs.uoregon.edu. For more information
40     about SPD see "A Proposal for Standard Graphics Environments," IEEE Computer
41     Graphics and Applications, vol. 7, no. 11, November 1987, pp. 3-5.
42    
43     By providing a minimal interface, NFF is meant to act as a simple format to
44     allow the programmer to quickly write filters to move from NFF to the
45     local file format. Presently the following entities are supported:
46     A simple perspective frustum
47     A positional (vs. directional) light source description
48     A background color description
49     A surface properties description
50     Polygon, polygonal patch, cylinder/cone, and sphere descriptions
51    
52     Files are output as lines of text. For each entity, the first line
53     defines its type. The rest of the first line and possibly other lines
54     contain further information about the entity. Entities include:
55    
56     "v" - viewing vectors and angles { optionally creates view file }
57     "l" - positional light location { it's there, but bad to use }
58     "b" - background color { ditto }
59     "f" - object material properties { this is flakey }
60     "c" - cone or cylinder primitive
61     "s" - sphere primitive
62     "p" - polygon primitive
63     "pp" - polygonal patch primitive { interpreted same as p for now }
64    
65     These are explained in depth below: { see conversion routines }

212     bottom pixel row and left column to right column.
213     Resolution: in pixels, in x and in y.
214    
215     Note that no assumptions are made about normalizing the data (e.g. the

221     Aspect ratio is 1.0.
222    
223     A view entity must be defined before any objects are defined (this
224     requirement is so that NFF files can be used by hidden surface machines).
