-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 |
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. |

< |
-DWFLUSH=(rays) Override for number of rays before flush in rview. |

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

-DBSD Operating system has a strong Berkeley flavor, meaning |
23 |
|
that bcopy() and bzero() are present but maybe memcpy() |
25 |
|
things this flag affects.) Also affects certain system |
26 |
|
calls, such as signal handling and resource tracking. |

-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). |

-DSMLMEM The system has little RAM available, so size hash |
29 |

tables and the like accordingly. Only allows for |
30 |

small scene descriptions (32,256 primitives). |

-DSMLFLT This setting tells Radiance to use short floats |
33 |
< |
(4-bytes) throughout, which saves lots of memory |
33 |
> |
(32 bits) throughout, which saves lots of memory |
34 |
|
but can cause calculation inaccuracies in many |
35 |
|
cases. Its use has been discontinued for this reason. |

-DSHADCACHE=N The array size to use for caching occluders. |
38 |
+ |
Setting this to 0 turns off this optimization. |
39 |
+ |
Values greater than 20 use over 4 Kbytes per |
40 |
+ |
light source, which can add up to a lot of |
41 |
+ |
memory in scenes with many sources. |
42 |

|
43 |

-DAVGREFL=R Set the average surface reflectance for the purpose |
44 |
+ |
of indirect irradiance calculations to R, where |
45 |
+ |
R is a real number in the range (0,1.0). The |
46 |
+ |
default value is 0.50 (50%). This value indirectly |
47 |
+ |
controls the maximum number of ambient bounces, |
48 |
+ |
which can never be more than the log of the -ad |
49 |
+ |
setting times the log of AVGREFL. |
