1141 +
1142 + ==============================
1143 + Version 3.6
1144 +
1145 + Modified 4-byte RGBE encoding routine to avoid problems
1146 + when one or two primary values is negative and the other(s)
1147 + positive.  This used to generate some strange color values.
1148 +
1149 + Added -oc option to rtrace to output local (u,v) coordinates.
1150 +
1151 + Fixed bugs in local uv and j unit vector variables in src/rt/func.c.
1152 +
1153 + Added warning message to OpenGL rendering routines about new
1154 + mesh primitive, which we cannot currently render.
1155 +
1156 + Added -if, -id, -of, and -od options to rcalc to provide for
1157 + binary float and double i/o.
1158 +
1159 + ****************** COMPATIBILITY CHANGE ***********************
1160 + Changed holodeck format to used off_t instead of long for beam
1161 + positions, which allows holodecks to grow to system file size limit.
1162 +
1163 + Fixed wrapping long in source hit test code, which would cause
1164 + odd horizontal lines in some very long renderings.
1165 +
1166 + Added -f and -w options to ra_tiff to create IEEE float and 16-bit/primary
1167 + TIFF output, respectively.  These formats are also understood on reverse
1168 + conversion.  (16-bit/primary has been understood for some time, but not
1169 + IEEE float.)
1170 +
1171 + Added -N option to rad to start multiple rendering processes in
1172 + parallel.
1173 +
1174 + Fixed bug where mesh instances were not being freed, so subsequent calls
1175 + in programs like ranimate would refer to bogus data.
1176 +
1177 + Added support in normtiff for floating-point and 16-bit/sample TIFF input
1178 + files.
1179 +
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.
1184 +
1185 + Fixed bug in xform where it was neglecting to add transform arguments
1186 + 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 + ****** COMPATIBILITY CHANGE ********
1194 + Changed local coordinate index from 32-bits to 16-bits, which requires
1195 + that Radiance mesh files be recompiled.
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
