+parallel.
+Fixed bug where mesh instances were not being freed, so subsequent calls
-<
+in programs like ranimate would refer to bogus data.
->
+in programs like ranimove would refer to bogus data.
+Added support in normtiff for floating-point and 16-bit/sample TIFF input
+files.
+Made similar change for virtual sources to allow modifiers and aliases
+on the mirror and prism types to work properly.
-+
-+
+Rob Guglielmetti added -lw and -lh options to falsecolor to control the
-+
+legend dimensions.  Made it so -lw 0 and/or -lh 0 turns legend off.
-+
-+
+Made it so pcompos will read everything from a stream even if it doesn't
-+
+need it, so input commands will not receive a hangup signal.
-+
-+
+Wrote ra_bmp program to convert to and from Windows BMP files (finally).
-+
+It's the most horrible image format I've ever seen, and I've seen a lot.
-+
-+
+Increased -aa default value for all renderers (and also -ad and -as in
-+
+rview) at Schorsch's suggestion.  I think this undid my earlier decrease
-+
+of -aa last time, which I guess was ill-considered.
-+
-+
+Modified oconv to keep subdividing the octree if there are too many
-+
+objects in a voxel even when the -r resolution limit has been
-+
+reached.  This was not done before due to problems with recursion,
-+
+and still, it will only continue to 256 times the original -r limit.
-+
+If that isn't enough, then there's probably no hope, anyway.
-+
-+
+Added -l option to obj2mesh to search for material files in library
-+
+locations.
-+
-+
+Increased polygon vertex limit to 512 in obj2mesh and obj2rad and added
-+
+warning if this limit is exceeded.
-+
-+
+Added tone-mapping and monitor primary options to ra_bmp.  This gives
-+
+new functionality similar to normtiff and ximage.  It would be nice to
-+
+add this feature to the other ra_* programs as well...  someday.
-+
-+
+Fixed long-standing bug in reported pixel ordering out of certain
-+
+protate commands.
-+
-+
+Added -p option to rcalc for "passive mode" that transmits
-+
+unrecognized input -- useful for substituting data in the
-+
+middle of a stream.
-+
-+
+Fixed a very obscure bug in rpict that caused a dark horizontal
-+
+line in certain cylindrical projections due to improper drawing
-+
+of the sky dome source in rt/srcdraw.c.
-+
-+
+Fixed problems with effective ray lengths computed for dielectric
-+
+and BRTDfunc materials.  This was most evident in breakup of holodeck
-+
+views when VDISTANCE=True.
-+
-+
+Fixed rad so that 'scene' variable may consist only of inline commands.
-+
-+
+Fixed bug introduced in shadow caching routines where sources in the
-+
+middle of spheres were not illuminating properly.  Thanks to Guilio
-+
+Antonutto for spotting this problem.
-+
-+
+Modified gensky behavior so if time is given with standard time zone
-+
+designation, any -m option is ignored.
-+
-+
+Added -n option to mkillum for (shared memory) parallel processing.
-+
-+
+Fixed a long-standing bug in parallel processing code that only
-+
+seemed to manifest with the new mkillum -n option, where rtrace
-+
+would deadlock upon termination.  The reason it never showed up
-+
+before is because I always closed processes in the reverse order
-+
+of opening them in other programs.  I went through and found similar
-+
+(potential) bugs in the rview device subprocess code and util/netproc.c.
-+
-+
+Corrected the normalization of the Gaussian reflectance model.  This will
-+
+cause an increase in specularity for low-lying light sources.
-+
+Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck
-+
+for pointing out this error.  The square root used for the two cosines
-+
+in the denominator of the normalization factor should not be present.
-+
+This was a serious mistake I made in the original model, which went
-+
+undiscovered (at least to my knowledge) for over a decade.  I think
-+
+Bruce Walter of Cornell may have known about it, but I never heard
-+
+the details of his discovery.
-+
-+
+Enabled the -p option for primary conversion without tone-mapping
-+
+in ra_bmp.  Also provides for XYZE input conversion to RGB.
-+
-+
+Fixed what I consider a bug in pvalue -o when taking XYZE files on input,
-+
+where it was inappropriately undoing the exposure value so that it always
-+
+reported radiance rather than XYZ values with Y in cd/m^2.
-+
-+
+Made it so ra_bmp only produces run-length encoded 8-bit output for
-+
+grayscale images that are tone-mapped.  This minimizes circumstances
-+
+under which output scanline order is reversed.
-+
-+
+Fixed bug in rcalc where it sometimes wasn't parsing the input format
-+
+correctly.
-+
-+
+=====================
-+
+Version 3.7
-+
-+
+Fixed bug in source occluder cache which caused consistency error
-+
+for distant sources and mist materials.  (Thanks to Mark Stock for
-+
+finding the problem.)
-+
-+
+Fixed serious bug in source drawing routines for rpict, where the edges
-+
+of light sources were appearing through obstructions.  (Thanks to Veronica
-+
+Sundstedt for pointing this out.)
-+
-+
+(The above were included in the 3.6.1 patch release.)
-+
-+
+Changed default temporary directory from /usr/tmp, which doesn't exist
-+
+on a lot of systems these days, to /tmp.
-+
-+
+Eliminated many unused files and programs from the distribution, including
-+
+the following programs that were being built but no longer used:
-+
+        oki20   - printer driver for OkiMate 20 printer (B&W)
-+
+        oki20c  - printer driver for OkiMate 20 color printer
-+
+        pcwarp  - intended as more general substitute for macbetcal,
-+
+                        but never quite worked
-+
+        ra_avs  - convert to & from AVS image format
-+
+        ra_bn   - convert to & from Barneyscann format
-+
+        ra_pr   - convert to & from 8-bit Sun rasterfile format
-+
+        ra_pr24 - convert to & from 24-bit Sun rasterfile format
-+
+        thf2rad - convert GDS "things file" to Radiance scene format
-+
+If anyone is still wanting any of the above programs, let us know and we'll
-+
+reinstate it.
-+
-+
+Fixed bug in pcond's acuity simulation for small view angles (less than
-+
+degrees horizontally or vertically).  Thanks to James Lee for figuring
-+
+this out.
-+
-+
+Added script to convert to/from ICT's Poskanzer Float Map, which I don't
-+
+care to support officially due to its machine-dependent byte order.
-+
-+
+Fixed bug that caused incorrect reporting of non-surface in set when
-+
+mixing meshes and instances.  (Thanks to Jack de Valpine for discovery.)
-+
-+
+Fixed innacuracy in calculation of diffuse transmission in the presence
-+
+of pure specular (Fresnel reflection) using "trans" material.  Thanks
-+
+to Christoph Reinhart for pointing out the error.
-+
-+
+Made internal change to tone-mapping library to use structure pointer
-+
+rather than stack, making code re-entrant and more up to modern standards.
