Here is a list of compile switches, used to customize Radiance code |
| 2 |
|
for specific machines and users: |
| 3 |
|
|
| 4 |
< |
-DMC If set, switches from default low-discrepency sequence |
| 5 |
< |
sampling to true (pseudorandom) Monte Carlo. Use if |
| 6 |
< |
the "brushed" appearance of specular highlights and |
| 7 |
< |
penumbras bothers you. |
| 8 |
< |
|
| 9 |
< |
-DALIGN=(type) Alignment type, machine-dependent. Most RISC |
| 4 |
> |
-DALIGNT=(type) Alignment type, machine-dependent. Most RISC |
| 5 |
|
architectures align on 8-word boundaries (double). |
| 6 |
|
The default alignment type is int. |
| 7 |
|
|
| 8 |
< |
-DSPEED=(MIPS) Millions of instructions per second for this |
| 14 |
< |
processor (approximate). This is used to decide |
| 15 |
< |
certain unimportant timing issues such as how many |
| 16 |
< |
rays to trace before checking input in rview and |
| 17 |
< |
whether or not to optimize the color table in ximage |
| 18 |
< |
on 8-bit displays. |
| 8 |
> |
-DWFLUSH=(rays) Override for number of rays before flush in rvu. |
| 9 |
|
|
| 10 |
< |
-DWFLUSH=(rays) Override for number of rays before flush in rview. |

-DBSD Operating system has a strong Berkeley flavor, which |
| 11 |
> |
affects certain system calls, such as signal handling and |
| 12 |
> |
resource tracking. |
| 13 |
|
|
| 14 |
< |
-DBSD Operating system has a strong Berkeley flavor, meaning |
| 15 |
< |
that bcopy() and bzero() are present but maybe memcpy() |
| 16 |
< |
and memset() are not. (See common/standard.h for other |
| 25 |
< |
things this flag affects.) Also affects certain system |
| 26 |
< |
calls, such as signal handling and resource tracking. |
| 14 |
> |
-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 |
|
|
| 28 |
– |
-DBIGMEM The system has lots of RAM available, so size hash |
| 29 |
– |
tables and the like accordingly. Also provides for |
| 30 |
– |
larger overall scene descriptions (33,553,920 primitives |
| 31 |
– |
rather than 32,256). |
| 32 |
– |
|
| 18 |
|
-DSMLFLT This setting tells Radiance to use short floats |
| 19 |
< |
(4-bytes) throughout, which saves lots of memory |
| 19 |
> |
(32 bits) throughout, which saves lots of memory |
| 20 |
|
but can cause calculation inaccuracies in many |
| 21 |
|
cases. Its use has been discontinued for this reason. |
| 22 |
+ |
|
| 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 |
+ |
|
| 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 |
+ |
default value is 0.50 (50%). |
