# Line 1180 | Line 1180 | files.
1180   Changed marksources() routine (src/rt/source.c) to check all
1181   primitives in the modifier chain for emitting types, not only
1182   the first.  This permits sources to be described with intervening
1183 < modifiers before the light/illum/glow primitive.
1183 > modifiers before the light/illum/glow primitive and allows aliases
1184 > as well.
1185  
1186   Fixed bug in xform where it was neglecting to add transform arguments
1187   to new mesh primitive.
# Line 1190 | Line 1191 | doubles, respectively.
1191  
1192   Changed meta2tga to output correct colors.
1193  
1193 ****** COMPATIBILITY CHANGE ********
1194   Changed local coordinate index from 32-bits to 16-bits, which requires
1195 < that Radiance mesh files be recompiled.
1195 > that Radiance mesh files be recompiled.  (Later decided against this
1196 > change, as it caused problems with some models.)
1197  
1198   Changed integer tone-mapping routines to better deal with images
1199   containing large, constant regions.
1200  
1201   Improved interaction with rholo -o ogl driver under OS X, which was
1202   returning bad values from the depth buffer.
1203 +
1204 + Minor bug fix in ranimove where it was restarting processes when it
1205 + didn't need to.
1206 +
1207 + Increased accuracy of default ambient parameters in rpict, rview, and
1208 + rtrace.  In rad program, doubled -ar value, -ad value, and -as value,
1209 + and decreased -aa value a bit.  Also adjusted -lr upwards and -lw
1210 + downwards.  I should have done these things long ago, as processors
1211 + have been getting faster and faster over the years.
1212 +
1213 + Fixed bug discovered by Marcus Jacobs where oconv was dumping core
1214 + when it was given too many modifiers.
1215 +
1216 + Fixed problem with rpict where it was drawing illum sources badly
1217 + even when they weren't all that small in the view.
1218 +
1219 + Added in(i) function to rcalc for more flexible channel evaluation.
1220 +
1221 + Replaced all calls to vfork() with regular fork() calls.
1222 +
1223 + Fixed bug in glarendx for dgr calculation with sources behind view.
1224 +
1225 + Added -p option to histo to print percentages/percentiles r.t. counts.
1226 +
1227 + Added a source occluder cache to accelerate shadow testing.  This
1228 + can save up to 50% of the calculation time in scenes with many
1229 + light sources, especially ones containing large occluders.  This
1230 + optimization may be tuned or switched off with the -DSHADCACHE=N
1231 + compile switch, where N is the resolution of the shadow cache, or
1232 + 0 to disable it.  Since this is purely a time vs. memory trade-off,
1233 + I decided not to make it a new command-line option.  (We already
1234 + have plenty.)
1235 +
1236 + ****** COMPATIBILITY CHANGE ********
1237 + Changed the following command names to avoid conflicts:
1238 +        rview -> rvu (with symbolic link back to rview)
1239 +        calc -> icalc
1240 +        lam -> rlam
1241 +        gencat -> gencatenary
1242 +
1243 + Improved -f option of normpat, which caused odd color changes before.
1244 +
1245 + Created pgblur script which does fast Gaussian blur of image without changing
1246 + its dimensions.  This is very useful in certain types of image processing
1247 + calculations, such as finding or removing low frequencies.
1248 +
1249 + ****** COMPATIBILITY CHANGE ********
1250 + Changed little-used objpict script so that it takes scene files rather than
1251 + rpict options on the command line, and puts everything into the right
1252 + coordinate position automatically rather than requiring the user to do it.
1253 +
1254 + Added -I option to replmarks for mesh instancing.
1255 +
1256 + Made similar change for virtual sources to allow modifiers and aliases
1257 + on the mirror and prism types to work properly.
1258 +
1259 + Rob Guglielmetti dded -lw and -lh options to falsecolor to control the
1260 + legend dimensions.  Made it so -lw 0 and/or -lh 0 turns legend off.
1261 +
1262 + Made it so pcompos will read everything from a stream even if it doesn't
1263 + need it, so input commands will not receive a hangup signal.
1264 +
1265 + Wrote ra_bmp program to convert to and from Windows BMP files (finally).
1266 + It's the most horrible image format I've ever seen, and I've seen a lot.
1267 +
1268 + Increased -aa default value for all renderers (and also -ad and -as in
1269 + rview) at Schorsch's suggestion.  I think this undid my earlier decrease
1270 + of -aa last time, which I guess was ill-considered.
