char *gf; : geometry file name |
| 141 |

char *pf; : portal file name(s) |
| 142 |
+ |
|
| 143 |
+ |
Add the given geometry file to the list of geometry to render for |
| 144 |
+ |
intermediate views if direct geometry rendering is available. The |
| 145 |
+ |
second argument gives the name(s) of any portal geometry files |
| 146 |
+ |
associated with this section. Multiple portal file names are separated |
| 147 |
+ |
by spaces. A single octree file will be given for the geometry, ending |
| 148 |
+ |
in the ".oct" suffix. Portal files will be given as zero or more |
| 149 |
+ |
Radiance scene description file names. If no portals are given for |
| 150 |
+ |
this section, the string may be NULL. The character strings are |
| 151 |
+ |
guaranteed to be static (or permanently allocated) such that they may |
| 152 |
+ |
be safely stored as a pointer. The same pointers or file lists may be |
| 153 |
+ |
(and often are) given repeatedly. If a given geometry file does not |
| 154 |
+ |
exist, the call should be silently ignored. If gf is NULL, then the |
| 155 |
+ |
last section has been given, and the display can be updated with the |
| 156 |
+ |
new information. |
