Revision 1.164 by greg, Sat Dec 12 19:00:59 2009 UTC

+Fixed bug in handling of views with tabs rather than spaces.
+Fixed bug related to alias of alias.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed default sky turbidity in gensky from the original default of
-+
+.75 to the CIE 110-1994 standard value of 2.45.  Thanks to Marilyne
-+
+Anderson of MIT for pointing out this discrepancy.
-+
-+
+Added -o option to ra_xyze to produce original pixel values.
-+
-+
+Fixed bug in tracing of virtual sources, where intervening glazing was
-+
+not being accounted for properly.
-+
-+
+Added -h option to pcompos and pcomb to eliminate verbose headers.
-+
-+
+=====================
-+
+Version 3.9
-+
-+
+Added -spec option to falsecolor to restore original spectral color scale.
-+
+Also added "-s auto" option to automatically set the maximum value.
-+
-+
+Added byte-swapping input and output to rcalc.
-+
-+
+Additional error-checking for source surfaces.
-+
-+
+Re-fixed bug in octree code that caused it to allocate 8 times as
-+
+much memory as it actually used(!) -- this was pointed out way back
-+
+in 1999 by Erik Reinhard and Erik Jansen, but the fix they gave me
-+
+got lost in the slightly broken release process at the time.  This
-+
+should make a big difference in memory usage, especially for the
-+
+new mesh primitive.  (I measured 30% less memory usage.)
-+
-+
+Corrected ray weights for material mixtures.
-+
-+
+Reduced the default -n setting for obj2mesh to take better advantage
-+
+of the smaller octree structure size.
-+
-+
+Fixed bug in shadow cache where it was adding surfaces with antimatter
-+
+holes cut in them to the obstructor list.  Thanks to John Mardaljevic
-+
+for discovering and reporting the problem.
-+
-+
+Adding ability in mkillum to incorporate BSDF data in calculation.
-+
+Internal interface (raypcalls) now used in place of rtrace process(es).
-+
-+
+Fixed pixel alignment in pcomb for size reduction and enlargement.
-+
-+
+Allow rtcontrib user to set -P and -PP options for persistent rendering.
-+
+The only caveat is that -n setting > 1 requires -PP rather than -P.
-+
-+
+Added -c option to rtcontrib to facilitate cumulative calculations.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Fixed long-standing bug in source.cal, which caused it to produce
-+
+reversed anisotropic photometric distributions due to the
-+
+misorientation of the y-axis.  Thanks to Zack Rogers for discovering
-+
+and helping debug this problem.
-+
-+
+Fixed long-standing bug in replmarks, where triangles with X-side
-+
+aligned with Z-axis would cause incorrect rotations.  Thanks to
-+
+Zack Rogers for finding this error.
-+
-+
+Added rsensor program to compute sensor signal for daylighting controls.
-+
+Funding for this component was provided by the Architectural Energy
-+
+Corporation in Boulder, CO, and directed by Zack Rogers.
-+
-+
+Added "planisphere" (stereographic) fisheye view type for traditional
-+
+daylighting analysis.  Feature requested & explained by Axel Jacobs.
-+
-+
+Modified -c option to rtcontrib so it can take a number of input
-+
+rays to average over, rather than only produce a single accumulated
-+
+record (which can now be done with -c 0).
-+
-+
+=====================
-+
+Version 4.0
-+
-+
+Added -n option to rvu to provide parallel rendering.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Changed ".pic" extension to ".hdr" in all sources and documentation
-+
+to improve interoperability with other software, since this has become
-+
+the de facto extension for Radiance RGBE and XYZE pictures.  Since file
-+
+extensions were never more than a convention in Radiance, this does not
-+
+affect operation, but may require the update of scripts, etc. written
-+
+by others that assume the ".pic" suffix for Radiance output.
-+
-+
+Added -N option to objview to support multiprocessing.
-+
-+
+Improved sampling of circular sources (source, sphere, ring types) with
-+
+quite a bit of help from David Geisler-Moroder.
-+
-+
+Added "rpict" and "rvu" variables to rad, and made these as well as
-+
+the "oconv", "mkillum" and "pfilt" variables accept an alternate
-+
+command path in each case.  Change suggested by Lars Grobe based
-+
+on similar Radzilla (radz) facility by Carsten Bauer.
-+
-+
+Fixed rad -v N specification to use actual view name if one.
-+
-+
+Fixed error in mkillum calculation where it neglected indirect
-+
+source contributions from BTDF illum's.
-+
-+
+Added GMT and LATLONG header lines for Greenwich Mean Time and
-+
+degrees North Latitude / East Longitude.
-+
-+
+Added gendaylit to distribution (finally).
-+
-+
+Added ability in vwright(1) to get view from command line arguments.
-+
-+
+Created genklemsamp(1) utility to generate samples suitable for
-+
+BSDF-based annual calculations.  This is the first Perl script to
-+
+be added to Radiance.  Hopefully, others will follow.
-+
-+
+Added klems_int.cal file to compute Klems bins for windows.
-+
-+
+Created gentregvec utility to sample a particular sky and
-+
+evaluate average radiance over the standard Tregenza sky patches.
-+
-+
+Created dctimestep program to compute a set of sensor values or
-+
+a combined image for a particular time using the daylight
-+
+coefficient method.
-+
-+
+Created src/rt/rayfifo.c for first-in/first-out handling of
-+
+multiprocessing by raypcalls.c.
-+
-+
+Added -n option to rtrace for executing on multiple cores
-+
+using new rayfifo calls.  Does not currently work with -I.
