# Line 1187 | Line 1187 | to new mesh primitive.
1187  
1188   Added -dF and -dD options to pvalue for byte-swapped floats and
1189   doubles, respectively.
1190 +
1191 + Changed meta2tga to output correct colors.
1192 +
1193 + Changed local coordinate index from 32-bits to 16-bits, which requires
1194 + that Radiance mesh files be recompiled.  (Later decided against this
1195 + change, as it caused problems with some models.)
1196 +
1197 + Changed integer tone-mapping routines to better deal with images
1198 + containing large, constant regions.
1199 +
1200 + Improved interaction with rholo -o ogl driver under OS X, which was
1201 + returning bad values from the depth buffer.
1202 +
1203 + Minor bug fix in ranimove where it was restarting processes when it
1204 + didn't need to.
1205 +
1206 + Increased accuracy of default ambient parameters in rpict, rview, and
1207 + rtrace.  In rad program, doubled -ar value, -ad value, and -as value,
1208 + and decreased -aa value a bit.  Also adjusted -lr upwards and -lw
1209 + downwards.  I should have done these things long ago, as processors
1210 + have been getting faster and faster over the years.
1211 +
1212 + Fixed bug discovered by Marcus Jacobs where oconv was dumping core
1213 + when it was given too many modifiers.
1214 +
1215 + Fixed problem with rpict where it was drawing illum sources badly
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
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.
