# Line 1222 | Line 1222 | Replaced all calls to vfork() with regular fork() call
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.
