# Line 2270 | Line 2270 | pabopto2bsdf).  The other input types already sampled
2270   Added gendaymtx -A option to compute average sky over all the input
2271   time steps.
2272  
2273 < Added ability to output color image from rtrace with any of -ovVWrx options.
2273 > Added ability to output color image from rtrace with any of -ovrx options.
2274 > Also fixed inconsistency of -oN output when ray casting versus full trace.
2275 > Before, it would flip normal to front side unless ray casting.  Now, -oN
2276 > always reports the unflipped normal.
2277 >
2278 > Changed rlam behavior so -iaN reads N lines from a stream rather than N
2279 > characters.  This seems more useful, since -ibN is somewhat redundant with
2280 > the old behavior.
2281 >
2282 > Created rsplit program as compliment to rlam and to handle more complex
2283 > rtrace output into separate files or streams.
2284 >
2285 > Improved getinfo so that it can also hop over resolution string with -c
2286 > and header elide mode.  Use +d to include resolution string in output,
2287 > and -d to elide with - and -c options.
2288 >
2289 > Made pvalue -u option mean "uncompressed" with -r.  Also, allow skipping
2290 > bytes on standard input.
2291 >
2292 > Created rcode_depth tool to convert to and from a 16-bit/pixel portable
2293 > depth image encoding that uses a mix of linear and reciprocal distance
2294 > with explicit representations of 0 and infinity.  Code for loading these
2295 > depth maps is in src/common/depthcodec.{h,c}.
2296 >
2297 > Created rcode_norm tool to convert to and from 32-bit/pixel portable
2298 > surface normal representation, matching the one in src/common/dircode.c.
2299 > Code for loading normal maps is in src/common/normcodec.{h,c}.
2300 >
2301 > Created rcode_ident tool to create indexed identifier files.
2302 > Code for loading these files is in src/common/idmap.{h,c}.
2303 >
2304 > Added -o* option to rtpict to produce layered images that handle most
2305 > output types from rtrace (colors, surface normals, distances, IDs).
2306 >
2307 > Created rcode2bmp script to create images from new rcode_* output maps.
2308 >
2309 > Improved efficiency of rmtxop in cases where matrix multiplication is
2310 > faster evaluated right-to-left, as when the final component is a
2311 > column vector.  Also added ability to apply trailing unary operators
2312 > (-t, and -s or -c) to resulting matrix.
2313 >
2314 > Added new depth, normal, and ID file types to radcompare.
2315 >
2316 > Added BigEndian= header line for automatic byte-swapping in rmtxop
2317 > and radcompare.  Doesn't work quite as automatically as it should
2318 > for pvalue -r, currently.
