Similar to data files, font files are usually read and stored in a |
| 1579 |
|
lookup table. |

The data structures for fonts are in src/common/font.h, and the routines |
| 1581 |

for reading and spacing them are in \f[C]src/common/font.c\f[R]. |

The routine \f[C]getfont(fname)\f[R] loads a font file from the |

The header file \f[C]src/common/octree.h\f[R] is needed in addition to |

the \f[C]src/common/object.h\f[R] file. |

The module \f[C]src/ot/writeoct.c\f[R] contains the main routines for |
| 1930 |
|
writing an octree to stdout, while \f[C]src/common/readoct.c\f[R] |
| 1931 |
|
contains the corresponding routines for reading an octree from a file. |
