Here is a list of compile switches, used to customize Radiance code
|
| 2 |
|
|
for specific machines and users:
|

|
|
|

1.6 |
-DALIGNT=(type) Alignment type, machine-dependent. Most RISC
|
| 5 |
greg |
1.1 |
architectures align on 8-word boundaries (double).
|
| 6 |
|
|
The default alignment type is int.
|
| 7 |
|
|
|

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

-DBSD Operating system has a strong Berkeley flavor, which
|
| 11 |
schorsch |
1.5 |
affects certain system calls, such as signal handling and
|
| 12 |
|
|
resource tracking.

-DSMLMEM The system has little RAM available, so size hash
|
| 15 |
|
|
tables and the like accordingly. Only allows for
|
| 16 |
|
|
small scene descriptions (32,256 primitives).
|
| 17 |
greg |
1.1 |
|
| 18 |
|
|
-DSMLFLT This setting tells Radiance to use short floats
|
| 19 |
greg |
1.2 |
(32 bits) throughout, which saves lots of memory
|
| 20 |
greg |
1.1 |
but can cause calculation inaccuracies in many
|
| 21 |
|
|
cases. Its use has been discontinued for this reason.
|
| 22 |
greg |
1.2 |
|
| 23 |
|
|
-DSHADCACHE=N The array size to use for caching occluders.
|
| 24 |
|
|
Setting this to 0 turns off this optimization.
|
| 25 |
|
|
Values greater than 20 use over 4 Kbytes per
|
| 26 |
|
|
light source, which can add up to a lot of
|
| 27 |
|
|
memory in scenes with many sources.

|
-DAVGREFL=R Set the average surface reflectance for the purpose
|
| 30 |
|
|
of indirect irradiance calculations to R, where
|
| 31 |
|
|
R is a real number in the range (0,1.0). The
|
| 32 |
greg |
1.6 |
default value is 0.50 (50%).
