rholo - generate/view a RADIANCE holodeck |
| 28 |
|
.I Rholo |

|
is a program for generating and viewing holodeck files. |

.I rholo |

can compute views interactively, but unlike |

it reuses any and all information that was previously computed in |

A section is a 6-sided parallel prism given by an origin and three axis |
| 211 |
> |
A section is a parallelepiped given by an origin and three axis |
| 212 |
|
vectors (i.e., 12 floating point values in world coordinates). |
| 213 |
|
The axis vectors define the three edges attached to the origin vertex, |
| 214 |
|
and the other edges and vertices are determined by the parallel wall |
| 218 |
|
In object rendering mode, a section may instead contain a detailed |
| 219 |
|
object to be viewed from the outside. |
| 220 |
|
The grid dimensions for each axis may also be given by three additional |
| 221 |
< |
integer arguments following the prism axes. |
| 221 |
> |
integer arguments following the three axes. |
| 222 |
|
Otherwise, if the grid dimensions are left out or any are unspecified |
| 223 |
|
or zero, the "GRID" variable will be used to determine them from the |
| 224 |
|
section axis lengths. |

Technically, the "RIF" setting is not necessary, but the results are |

.I rholo |

on the above file to compute a hologram overnight in batch mode: |

This will report progress every hour to "elect.her". |

The next morning, we can look at the holodeck interactively: |

.IP "" .2i |

rholo -n 1 -o x11 elect.hdk & |

|
If the previous command were still running, the above command would |
| 560 |
|
fail because the permissions on the holodeck would not grant access. |
| 596 |
|
the file size limit and permit the holodeck |
| 597 |
|
to be clobbered by a command entered on the standard input: |
| 598 |
|
.IP "" .2i |

< |
rholo -n 1 -o x11 -i -f elect.hdk + DISK=0 |
