This tool may be used to do standard optical ray tracing or daylight coefficient calculations for annual simulations, among other uses. + +Added tilde ('~') output option as part of the -o* specification of +rtrace. This permits ray trees to be parsed more easily in binary +output mode, as needed by rtcontrib. + +Implemented Russian roulette ray termination with -lr <= 0. +Made -lr -10 the default in rtcontrib. + +Made rtcontrib -f option search RAYPATH directories. + +Made it so -o option of rtcontrib can pipe -o output to a command. + +Added -if and -of options to total for binary i/o (following rcalc mold). + +Switched default options in rtrace to use Russian roulette. (Rpict and rvu +still use biased ray termination.) + +Added rtcontrib -r option to recover partial output. + +Added -u rendering option for pure Monte Carlo sampling. +(Got rid of -DMC compile option, which this makes superfluous.) + +Changed -t option of rlam to accept strings as well as single characters. + +Fixed bug in rcalc with -l option where it would sometimes go into an +infinite loop. + +Fixed truly ancient bug in bounding box computation for cones, which +could (and did) cause missing segments. + +Added -z option to normtiff to output LZW-compressed files. + +Last change to total causes it to produce results when it sees an empty +line on the input. This was not intentional, but I decided I like this +behavior so I documented it rather than changing it.
