| 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 | 
| 1241 | + |  | 
| 1242 | + | Improved -f option of normpat, which caused odd color changes before. | 
| 1243 | + |  | 
| 1244 | + | Created pgblur script which does fast Gaussian blur of image without changing | 
| 1245 | + | its dimensions.  This is very useful in certain types of image processing | 
| 1246 | + | calculations, such as finding or removing low frequencies. | 
| 1247 | + |  | 
| 1248 | + | ****** COMPATIBILITY CHANGE ******** | 
| 1249 | + | Changed little-used objpict script so that it takes scene files rather than | 
| 1250 | + | rpict options on the command line, and puts everything into the right | 
| 1251 | + | coordinate position automatically rather than requiring the user to do it. | 
| 1252 | + |  | 
| 1253 | + | Added -I option to replmarks for mesh instancing. |
