Welcome to the second major release of the MGF language and parser library.
|
| 5 |
greg |
1.1 |
If you have not read it already, you should take a look at the documentation
|
| 6 |
|
|
in the troff file "mgfdoc.tr". This can be printed out using the -ms
|
| 7 |
|
|
macro package, or by sending the file "mgfdoc.ps" to a PostScript printer.
|
| 8 |
|
|
The figures for this document are contained in "figures.ps", which may
|
| 9 |
|
|
also be sent to a PostScript printer, or displayed with ghostview (if you
|
| 10 |
|
|
have it).
|
| 11 |
|
|
|
| 12 |
|
|
Most of the source files go directly into the parser library, with
|
| 13 |
|
|
the following exceptions:
|
| 14 |
|
|
|
| 15 |
|
|
face2tri.C - C++ converter from polygons to triangles
|
| 16 |
greg |
1.2 |
mgf2inv.c - MGF to Inventor converter, complete
|
| 17 |
greg |
1.1 |
mgf2rad.c - MGF to Radiance converter, missing some libraries
|
| 18 |
|
|
mgfilt.c - MGF to MGF filter, compiled in Makefile
|
| 19 |
|
|
rad2mgf.c - Radiance to MGF converter, missing some libraries
|
| 20 |
greg |
1.3 |
3ds2mgf.c - 3D-Studio to MGF converter, complete with below
|
| 21 |
|
|
optray.[ch] - Triangle smoothing code used by 3ds2mgf
|
| 22 |
|
|
vect.[ch] - Vector and matrix code used by 3ds2mgf
|

The Makefile creates three useful items:
|
| 25 |
greg |
1.1 |
|
| 26 |
|
|
mgfilt - a filter for MGF
|
| 27 |
|
|
libmgf.a - the MGF parser library
|
| 28 |
greg |
1.2 |
mgf2inv - a translator from MGF to Inventor (or VRML) format
|
| 29 |
greg |
1.3 |
3ds2mgf - a translator from 3D-Studio to MGF
|
| 30 |

Before you compile, you should probably check to make sure that the
|
| 32 |
|
|
compiler and flags you like are included. If you're like me and lack
|
| 33 |
|
|
an ANSII-compatible C compiler on your machine, use the -DNOPROTO flag
|
| 34 |
|
|
to take out function prototypes and get back K&R compatibility.
|
| 35 |
greg |
1.3 |
|
| 36 |
|
|
The exception to this is 3ds2mgf, which requires an ANSI-C compiler with
|
| 37 |
|
|
prototypes. Because of this requirement, the program must be built
|
| 38 |
|
|
explicitly with "make 3ds2mgf".
