| 1216 |  | even when they weren't all that small in the view. | 
| 1217 |  |  | 
| 1218 |  | Added in(i) function to rcalc for more flexible channel evaluation. | 
| 1219 | + |  | 
| 1220 | + | Replaced all calls to vfork() with regular fork() calls. | 
| 1221 | + |  | 
| 1222 | + | Fixed bug in glarendx for dgr calculation with sources behind view. | 
| 1223 | + |  | 
| 1224 | + | Added -p option to histo to print percentages/percentiles r.t. counts. | 
| 1225 | + |  | 
| 1226 | + | Added a source occluder cache to accelerate shadow testing.  This | 
| 1227 | + | can save up to 50% of the calculation time in scenes with many | 
| 1228 | + | light sources, especially ones containing large occluders.  This | 
| 1229 | + | optimization may be tuned or switched off with the -DSHADCACHE=N | 
| 1230 | + | compile switch, where N is the resolution of the shadow cache, or | 
| 1231 | + | 0 to disable it.  Since this is purely a time vs. memory trade-off, | 
| 1232 | + | I decided not to make it a new command-line option.  (We already | 
| 1233 | + | have plenty.) | 
| 1234 | + |  | 
| 1235 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1236 | + | Changed the following command names to avoid conflicts: | 
| 1237 | + | rview -> rvu (with symbolic link back to rview) | 
| 1238 | + | calc -> icalc | 
| 1239 | + | lam -> rlam | 
| 1240 | + | gencat -> gencatenary |
