1 Here is a list of compile switches, used to customize Radiance code
2 for specific machines and users:
4 -DALIGN=(type) Alignment type, machine-dependent. Most RISC
5 architectures align on 8-word boundaries (double).
6 The default alignment type is int.
8 -DSPEED=(MIPS) Millions of instructions per second for this
9 processor (approximate). This is used to decide
10 certain unimportant timing issues such as how many
11 rays to trace before checking input in rvu and
12 whether or not to optimize the color table in ximage
13 on 8-bit displays.
15 -DWFLUSH=(rays) Override for number of rays before flush in rvu.
17 -DBSD Operating system has a strong Berkeley flavor, meaning
18 that bcopy() and bzero() are present but maybe memcpy()
19 and memset() are not. (See common/standard.h for other
20 things this flag affects.) Also affects certain system
21 calls, such as signal handling and resource tracking.
23 -DSMLMEM The system has little RAM available, so size hash
24 tables and the like accordingly. Only allows for
25 small scene descriptions (32,256 primitives).
27 -DSMLFLT This setting tells Radiance to use short floats
28 (32 bits) throughout, which saves lots of memory
29 but can cause calculation inaccuracies in many
30 cases. Its use has been discontinued for this reason.
32 -DSHADCACHE=N The array size to use for caching occluders.
33 Setting this to 0 turns off this optimization.
34 Values greater than 20 use over 4 Kbytes per
35 light source, which can add up to a lot of
36 memory in scenes with many sources.
38 -DAVGREFL=R Set the average surface reflectance for the purpose
39 of indirect irradiance calculations to R, where
40 R is a real number in the range (0,1.0). The
41 default value is 0.50 (50%). This value indirectly
42 controls the maximum number of ambient bounces,
43 which can never be more than the log of the -ad
44 setting times the log of AVGREFL.
