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 |
|
|
|

1.2 |
-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. |
28 |
greg |
1.3 |
|
29 |
|
|
-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%). |
