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 |
|
|
| 13 |
– |
-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 rvu and |
| 17 |
– |
whether or not to optimize the color table in ximage |
| 18 |
– |
on 8-bit displays. |
| 19 |
– |
|
| 8 |
|
-DWFLUSH=(rays) Override for number of rays before flush in rvu. |
| 9 |

-DBSD Operating system has a strong Berkeley flavor, meaning |
| 11 |
< |
that bcopy() and bzero() are present but maybe memcpy() |
| 12 |
< |
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. |

|
-DSMLMEM The system has little RAM available, so size hash |
| 15 |
|
tables and the like accordingly. Only allows for |
| 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%). |
