-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. |
| 19 |

< |
-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). |
| 28 |

-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. |
