Add the given octree file to the list of geometry to be used to render |
| 138 |
< |
intermediate views if direct geometry rendering is available. Additional |
| 139 |
< |
file names (separated by spaces) are Radiance scene files containing |
| 140 |
< |
the geometry for "portals" to separate sections. The given |
| 141 |
< |
character string is guaranteed to be static (or permanently allocated) |
| 142 |
< |
such that it may be safely stored as a pointer. The same pointer or |
| 143 |
< |
file list may be (and often is) given repeatedly. If a given octree |
| 144 |
< |
does not exist, the call should be silently ignored. If otn is NULL, |
| 145 |
< |
then the last octree has been given, and the display can be updated |
| 146 |
< |
with the new information. |

Add the given geometry file to the list of geometry to render for |

intermediate views if direct geometry rendering is available. The |

second argument gives the name(s) of any portal geometry files |
| 140 |

associated with this section. Multiple portal file names are separated |
| 141 |
> |
by spaces. A single octree file will be given for the geometry, ending |
| 142 |
> |
in the ".oct" suffix. Portal files will be given as zero or more |
| 143 |

Radiance scene description file names. If no portals are given for |
| 144 |

this section, the string may be NULL. The character strings are |

exist, the call should be silently ignored. If gf is NULL, then the |

last section has been given, and the display can be updated with the |

new information. |
