[ViewVC] Annotation of: radiance/ray/doc/notes/compile_switches

Here is a list of compile switches, used to customize Radiance code
for specific machines and users:

-DALIGNT=(type) Alignment type, machine-dependent.  Most RISC
                architectures align on 8-word boundaries (double).
                The default alignment type is int.

-DWFLUSH=(rays) Override for number of rays before flush in rvu.

-DBSD           Operating system has a strong Berkeley flavor, which
                affects certain system calls, such as signal handling and
                resource tracking.

-DSMLMEM        The system has little RAM available, so size hash
                tables and the like accordingly.  Only allows for
                small scene descriptions (32,256 primitives).

-DSMLFLT        This setting tells Radiance to use short floats
                (32 bits) throughout, which saves lots of memory
                but can cause calculation inaccuracies in many
                cases.  Its use has been discontinued for this reason.

-DSHADCACHE=N   The array size to use for caching occluders.
                Setting this to 0 turns off this optimization.
                Values greater than 20 use over 4 Kbytes per
                light source, which can add up to a lot of
                memory in scenes with many sources.

-DAVGREFL=R     Set the average surface reflectance for the purpose
                of indirect irradiance calculations to R, where
                R is a real number in the range (0,1.0).  The
                default value is 0.50 (50%).
